HOW TO ENABLE     >>>> VERY IMPORTANT <<<<
To enable each KeyRinger, double click the blue button. Five short beeps will indicate that the KeyRinger is enabled. KeyRingers are shipped from the factory with the circuitry disabled to guarantee that your batteries will be fresh.

WHERE TO USE
The KeyRinger is used for locating missing objects such as keys, eyeglass cases, television remotes, purses and other commonly misplaced items. To protect an item, simply attach a KeyRinger. If the item that you are attaching a KeyRinger to has a hard flat surface, attach the KeyRinger using one of the included pieces of double-sided foam tape. If you want to keep one of your KeyRingers handy at all times, you can keep it in your pocket, purse, desk drawer, car or attached to your refrigerator using the included stick-on magnet. To use the stick-on magnet or double-sided foam tape, peel off the protective backing and press one side onto the back of the KeyRinger and the other side onto the item.

To find a misplaced item, simply use the KeyRinger that you have not misplaced to find the KeyRinger attached to the item that you have misplaced. For example, if your keys are missing, the KeyRinger attached to the television remote can be used to locate your keys; and if the television remote is missing the KeyRinger attached to your keys can be used to locate the remote. If you find yourself frequently misplacing both KeyRingers at the same time, you can purchase additional KeyRingers and keep at least one in a safe place such as attached to your refrigerator using the stick-on magnet.

HOW TO OPERATE
To use a KeyRinger, double click (quickly press twice) the blue find button and you should immediately hear five short beeps. For maximum range, aim the sound deflector on the face of the Key Ringer in the direction that you are searching being careful not to block the sound deflector with you hand or fingers. The KeyRinger that you are searching for will beep and flash for 15 seconds.

If you do not find the missing KeyRinger on the first attempt, press the button again. For convenience, the button only has to be single clicked if pressed again within 15 seconds. In noisy locations it may be necessary to activate the KeyRinger two or three times before the misplaced KeyRinger responds. When the misplaced KeyRinger responds, it does so by flashing a red light and generating an alternating tone for about 15 seconds. To stop the alarm sooner, press the find button on the flashing KeyRinger.

FLASHLIGHT
The KeyRinger can be used as a flashlight to locate small items in the dark such as a keyhole. To use the KeyRinger as a flashlight, press the find button. Do NOT double click the button. Doing so will activate the search tones as well as the flashlight. To prevent the battery from being drained in the event that the button is accidentally held down, the light automatically turns off after 25 seconds. To continue using the flashlight after 25 seconds, release the button and press again.

TEMPORARY DEACTIVATION
When two or more KeyRingers are within range, the KeyRingers that you are NOT searching for will most likely respond as well. To simplify your search, you can temporarily deactivate the extra KeyRingers. To silence a KeyRinger for three minutes, double click it as previously described and then continue to hold down the button for an additional one to two seconds until a short double beep is heard. After the short double beep, immediately release the button and the KeyRinger will not respond for three minutes or until its button is again pressed.

LONG-TERM DEACTIVATION
To deactivate your KeyRinger, hold the button down (do not double click) for approximately 30 seconds. While you hold the button down, the light will stay on for 25 seconds, go off for 5 seconds and then go on again, at which time you must immediately release the button. To re-enable your KeyRinger, repeat the same procedure or simply double click the blue find button.

CONTINUOUSLY FLICKERING LIGHT
It may be desirable to have the KeyRinger flicker whenever you make the slightest sound, especially a hissing sound. The flickering light makes the KeyRinger very easy to find in the bottom of a purse or when dropped on the ground at night. To enable the flickering, hold the button down (do not double click) for approximately 40 seconds. While you hold the button down, the light will stay on for 25 seconds, go off for 5 seconds, go on for 2 seconds, go off again, and then go on again, at which time you must immediately release the button. The flickering light will not significantly shorten the battery life. To disable the flickering, repeat the same procedure.

BATTERIES
Each KeyRinger uses two batteries that should last approximately twelve months. The battery life will be shortened, however, if the KeyRinger is kept in a noisy location such as near loud machinery or near a loud air conditioning vent for extended periods.

The batteries should be replaced when the KeyRinger produces soft low-pitched tones instead of the normally generated tones, or when the unit fails completely. To replace the batteries, separate the top and bottom halves of the KeyRinger by twisting a medium to large size screwdriver in the slot located at the flat end of the case.

After the flat end of the case partially opens, insert the screwdriver into the opening and work it around inside the end of the case until the two halves separate. To prevent cosmetic damage to the case, do not open the case from the sides.

To guarantee that KeyRinger operates properly when the new batteries are installed, hold the blue double-click button down for about ten seconds before snapping the case together with the new batteries. Press the button with one finger and support the circuit board with an opposing finger.

Install two new lithium batteries (CR2032), carefully observing the polarity of each battery.

The battery near the rounded end of the case must be installed (+) side UP and the battery near the flat end must be installed (+) side DOWN. The batteries, also, can be installed correctly by observing the diagram inside the case.

Replacement batteries can be purchased at most computer and electronic retail stores or through the KeyRinger web site www.keyringer.com at a substantial discount.

Warnings: Do not attempt to recharge, disassemble or dispose of in a fire. Dispose of the used batteries promptly and keep away from children.

SAFETY PRECAUTIONS
Do not hold a KeyRinger close to your ears or anyone else's ears. The sound generated by the KeyRinger is loud enough to be painful if held too close to one's ear.

So that you will not be startled, be aware that the KeyRinger will occasionally false alarm due to sounds present in the area.

If you have any questions about your new KeyRinger, please contact our customer service department by phone at 510-339-8200 or by e-mail at service@keyringer.com. You can also visit our web site at www.keyringer.com.

What items can I locate with the KeyRinger?

The KeyRinger can be attached to and be used to locate almost any item. Typical items include, keys, TV remote, purse, eyeglass case, and cell phones. However, you can be creative and attach the KeyRinger to such items as an emergency flashlight or that tape measure that you’re always searching for.

How far away will a KeyRinger respond?

A KeyRinger will respond up to 300 feet away under ideal conditions. Obstructions and noise will reduce the range. In general, if you are close enough to a KeyRinger to hear it responding (beeping and flashing), it will respond when called using another KeyRinger.

Do I need to know how to whistle or clap my hands a certain way to use the KeyRinger?

No, you do not have to whistle a certain tone or clap your hands in a precise pattern as you have to with some other key finding devices. The problem with devices that respond to a clap or whistle is that when they don’t respond you don’t know whether you clapped or whistled incorrectly, or the device is not in the vicinity. With the KeyRinger, you simply click the find button on the other KeyRinger to generate a precise tone sequence. Because the KeyRinger, not you, makes the sounds needed to alert the other KeyRinger, anybody, young or old, can reliably use the KeyRinger.

Will the KeyRinger ever false alarm?

Yes, but extremely infrequently compared to devices that respond to whistling or clapping. The clap or whistle type devices have to accept a wide range of sounds to accommodate variations in different people’s claps or whistles. But because they have to respond to such a broad range of sounds, they respond (false alarm) to various random sounds as well. The KeyRinger, on the other hand, is listening for the precise microprocessor-controlled tone sequence generated by the another KeyRinger. Because the KeyRinger can reject all other sounds, it is far less susceptible to false alarms. When the KeyRinger does false alarm, however, it is usually as the result of a hissing type sound such as that produced by a loud exhaust or air conditioning fan, or the water running in a sink.

How does the KeyRinger work?

The KeyRinger is constantly listening for the four-beep tone sequence that is produced when the find button on another KeyRinger is double-clicked. After the misplaced KeyRinger hears the beginning of the first tone, the microprocessor in the KeyRinger turns on and the sounds that follow are carefully analyzed. If the microprocessor in the misplaced KeyRinger determines that that what it heard were the four tones from another KeyRinger, it begins to beep and flash. If the microprocessor in the KeyRinger determines that the sounds it heard were not the four tones from another KeyRinger, the KeyRinger remains silent and the microprocessor shuts down until another sound is heard. Note that the microprocessor in the KeyRinger shuts down in the absence of any sounds to extend the KeyRinger’s battery life.

Why do I have to double-click the KeyRinger sometimes but not other times?

Whenever you first use the KeyRinger you must double-click the find button. If it were only necessary to single click the find button, the KeyRinger could accidentally activate while in your pocket when you sit down, for example. For convenience, however, if you press the find button again within fifteen seconds of a previously activation, you only have to single-click the find button.

Why do I sometimes have to press the find button more than once before the KeyRinger responds?

In quiet locations, you usually only have to click or double-click the find button on a KeyRinger once to cause the missing KeyRinger to respond. In noisy locations, it is sometimes necessary to click or double-click the find button two or three times (each click within ten seconds of the previous click) before the missing KeyRinger responds. When a KeyRinger hears the four-beep tone sequence and then quiet, it responds immediately. When a KeyRinger hears the tone sequence but fails to observe a quiet period immediately afterwards, it waits until it hears the four-beep tone sequence again within ten seconds. When in a noisy environment, the requirement that the four-beep tone sequence be heard twice within ten seconds greatly reduces instances of false alarms.

Why does the red light on the KeyRinger keep flashing?

The light can be set to constantly flicker so that the KeyRinger can be easily located, for example, when you drop it outside at night or need to quickly find it in the bottom of a purse. Sometimes the KeyRinger may accidentally go into flicker mode. To turn off the flickering, refer to CONTINUOUSLY FLICKERING LIGHT in the KeyRinger instructions for direction on how to disable the flickering.

How long do the batteries in the KeyRinger last?

The batteries in the KeyRinger will last approximately 12 months under normal conditions. If a KeyRinger is stored in a noisy location, the battery life will be shortened.

Where can I purchase replacement batteries for the KeyRinger?

Each KeyRinger uses two 2032 lithium batteries. The batteries can be purchased at most retail computer or electronics stores. Replacement batteries can also be purchased at a substantial discount in packs of eight through the KeyRinger web site. To order batteries, simply click on Order Now and provide the requested information. To replace the batteries refer to BATTERIES in KeyRinger Instructions.

How do I use the KeyRinger as a flashlight?

To use the KeyRinger as a flashlight, simply hold down the find button. Do not double-click the button; doing so will activate the four-beep tone sequence instead of the light. Refer to FLASHLIGHT in the KeyRinger Instructions for a more detailed description on how to use the KeyRinger as a flashlight.

Why do double-sided adhesive strips and a stick-on-magnet come with the KeyRingers?

The double-sided foam adhesive strips are provided to attach KeyRingers to items such as your TV remote. The stick-on magnet should be applied to the back of a KeyRinger if you want to keep it handy by magnetically sticking it on your refrigerator or office filing cabinet. Refer to WHERE TO USE in the KeyRinger Instructions for details on how to apply the adhesive strips or magnet.

Can I use more than two KeyRingers at one time?

Yes, you can use KeyRingers to protect as many items as you want. All KeyRingers currently being sold are identical, thus multiple sets of KeyRingers will all work with each other. (Note, in September 2004, the frequency of the sound generated by the KeyRinger was lowered to allow it to be heard more easily by older individuals. All KeyRingers purchased before September 2004, will respond to each other, and all KeyRinges purchased since September 2004, will respond to each other. KeyRingers purchased before and after September 2004 will NOT respond to each other.) If there is more than one KeyRinger in the vicinity where you are searching, multiple KeyRingers may respond, complicating your search. To resolve this potential problem, a KeyRinger can be deactivated (will not respond) for three minutes at a time by double-clicking the find button and holding it down for an additional second until a short double-beep is heard. Refer to TEMPORARY DEACTIVATION in the KeyRinger Instructions for further details.

Can I buy an additional single KeyRinger?

No, we do not sell single KeyRingers at this time.

What do I do if I misplace both KeyRingers from the set?

Unfortunately, we do not have a magic answer. You could borrow someone else’s KeyRinger to find yours, or you could purchase an additional pair. If you do have to purchase another pair of KeyRingers, you can always use them to protect additional items.

Does the KeyRinger come with a warranty?

KeyRingers come with a 30-day money-back guarantee. KeyRingers are also warranted against defects for ninety days from date of purchase. Refer to LIMITED WARRANTY in the KeyRinger Instructions for further details.

What do I do if I have questions or problems with the KeyRinger?

If you have problems, you should refer to the KeyRinger Instructions, specifically the section entitled BATTERIES. If you cannot resolve the problem yourself after reading the instructions, you can contact Sierra Systems either by telephone at 510-339-8200 or by sending an e-mail to support@keyringer.com with your questions or description of the problem.
