Find One Find All™ Keyfinder
RadioShack
Congratulations on the purchase of your FOFA™ keyfinder. Your FOFA is a keyfinder system
that can be expanded up to 36 unique FOFA units. You attach them to objects that are easily
lost. If you can find one FOFA, you can find them all!
OVERVIEW
Each FOFA unit can find any other FOFA unit in a range up to 30 feet. FOFA keyfinders are
sold in pairs. Each FOFA unit belongs to a Set that you define. You can have up to 6 unique
Sets of 6 FOFA Items for a total of 36 unique FOFA units. Your FOFA units come with plastic
stickers for customizing the buttons of each FOFA.
USING FOFA FOR THE FIRST TIME
Before you can begin using your FOFA, you must install the batteries and set each unit.
INSTALLING OR REPLACING THE BATTERY
Each FOFA needs one CR2032 battery (supplied). When the FOFA stops working properly,
replace the battery. Follow these steps to install/replace the battery:
1. Pull out the battery tray and take out the old battery (if present).
2. Place the new battery on the tray with + face up.
3. Push in the battery tray.
4. When the FOFA beeps and the LED begins to flash, you will need to set FOFA’s Identity
(See “Setting FOFA”). If you don’t set it in time before the flashing stops, you can re-enter the
set-up mode by pressing any key on the keypad (Also see “Setting FOFA”).
CAUTIONS:
1. Use only fresh batteries of required size and recommended type.
2. If you do not want to use the FOFA for a month or more, remove the battery.
WARNING: Dispose of the old battery promptly and properly. Do not burn or bury it.
QUICK SETUP
Many first-time FOFA owners set their first FOFA pair to Set 1, Item 1 and Set 1, Item 2
respectively. To do this, immediately after installing the battery, press “1”, then ”1” again on the
first FOFA and press “1”, then “2” on the second FOFA For more details, see “Setting FOFA”.
IMPORTANT: FOFA’s only locate other FOFA’s within their Set number; (the first number you
enter when setting) however, you can easily re-program your FOFA to find units in other sets at
any time. .
SETTING FOFA
You can set FOFA to your desired Set (Set 1, Set 2…Set 6) and Item (up to 6 items). Follow
these steps to set FOFA:
1. If you have just installed the battery, FOFA goes into setup mode immediately without having
to press any keys (I.e. proceed to Step 2). To enter Setup mode at any other time, press
and hold the 1 and 3 keys at the same time until the FOFA unit has beeped and flashed 4
times. The LED will begin flashing slowly.
2. Press one number key on the FOFA unit to define the Set number. The LED will begin
flashing quickly.
3. Press another number key on the FOFA unit to define the Item number. The LED stops
flashing.
4. The new identity setting is then read back to you by the FOFA unit. The first series of beeps
indicates the Set number. After a brief pause, the next series of beeps indicates the Item
number. Setting is complete!
CHECK SET AND ITEM NUMBER OF ONE FOFA
To verify the identity (Set number and Item number) of each FOFA, follow these steps:
1. Press and hold the 5 and 6 keys at the same time
2. A high pitched beep and short flash is followed by the identification beeps. The first series
of beeps corresponds to the Set number. After a brief pause, the next series of beeps
corresponds to the Item number.
3. No further steps are necessary to exit the identify mode.
ATTACHING FOFA
You can attach one FOFA to easily lost objects using either the provided key ring or double
sided tape.
OPERATION
To find a lost object, locate one of your other FOFA units and press the key that
corresponds to the FOFA on the lost object. The FOFA you are holding will begin to flash
slowly. If you are within range of the FOFA attached to the lost object, you will begin to
hear it beep and see the LED flash. (Note: If you hear 4 quick beeps, you have pressed
the key corresponding to the FOFA unit your are holding.)
If you press and hold the number corresponding to the FOFA you are holding, after the 4
quick beeps, the light from the bright LED can be used to assist in finding keyholes.
NOTES:
For best results, hold the FOFA unit with the LED pointing away from you.
Move around while searching for an object. This can improve the clarity of the radio
frequency signal.
Keep the FOFA far away from the large metal objects and other radio source that might
reduce the transmitter range.
To avoid confusion, use only one FOFA to search for the lost object.
Quiet other sounds so that you can more easily identify the direction of the beep sound from
the object you are looking for.
SUGGESTED USES
Each member in a family can have his or her own Set number.
Assign objects of the same type (i.e. TV remotes or cordless phones) to the same Set
number.
Set # Item # Suggested Use
1 1 Dad’s Keys
1 2 Dad’s Wallet
2 1 Mom’s keys
2 2 Mom’s purse
3 1-6 All remotes
4 1 Medical appliance (i.e. nebulizer, glucometer, etc.)
CARE and MAINTENANCE
Keep the FOFA dry; if it gets wet, wipe it dry immediately. Use and store the FOFA only in
normal temperature environments. Handle the FOFA carefully; do not drop it. Keep the FOFA
away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new.
TROUBLESHOOTING
1. If you cannot find a FOFA unit, trying replacing the batteries of the unit you are using or
consider using another FOFA unit that might have a stronger battery.
2. If you cannot find a FOFA unit, you may want to experiment changing the Set number of the
unit you are using to locate the lost item. FOFA’s only locate other FOFA’s within their Set
number. To change the Set number, see “Setting FOFA”.
3. If you receive 4 rapid beep tones when pressing a button on a FOFA unit and the LED does
not begin to flash, you have just pressed the button corresponding to that FOFA. Press the
correct button corresponding to the FOFA item number of the misplaced object.
4. If a FOFA beeps whenever any key is pressed on another FOFA, the FOFA unit has not
been set. See “Setting FOFA”.
5. If the FOFA unit appears to be dead, try removing and re-installing the battery. If the unit
still does not respond, you will need to replace the battery. Remember to reset the Set and
Item number. See “Setting FOFA”
