OWNER'S MANUAL FOR THE F-20 (FRS W/532 CODES)
Instructions for optional charger
Install NI-Cad (nickel cadmium) batteries observing their polarity. Plug the 18-396 charger into
any 110/115 V wall socket. Plug the
rubber plug marked "CHG". Charge
hours for Ni-MH.. When using a drop-in charger (models 18-383 or 18-385) follow the setup
instructions then simply set the radio in the charger stand and observe that the LED on the
charger is lit. The radio should be turned off while charging.
DO NOT attempt to charge any type of Alkaline batteries in this radio.
The F-20 comes standard with a belt clip. Attach it to the radio back by sliding the top of the clip
up over the two rectangular bosses on the back of the radio until it snaps into place. To detach
the belt clip, press the lever inside the top of the clip away from the radio body and slide the clip
toward the bottom of the radio.
1.
Install fresh alkaline or fully charged Ni-Cad or Ni-MH batteries.
2.
Turn the unit on by turning the ON/OFF/VOLUME clockwise until a click is heard.
3.
Use the ON/OFF/VOLUME control to adjust the volume. To test the volume setting, press
and hold the "MON" button so static noise can be heard. The noise can be used as a
reference level for volume setting.
4.
To talk press the PTT (push to talk) button on the left side of the radio and talk in a normal
voice into the front of the radio about three inches away from your mouth.
To listen release the PTT button.
This part of the operation of the radio is completely automatic and not adjustable. When the radio
has not transmitted or received a signal for several seconds it will begin to cycle from a sleep
mode to fully on. This occurs several times a minute. If a signal is received or you cause the radio
to transmit, the radio will become fully awake. This cycling from sleep to fully on increases the
battery life more than 50%. An icon in the upper right of the display flashing "SAVE" will verify
this.
The best range between portable FRS radios is achieved when they are operating in open terrain
outside of buildings and vehicles. Anyone using a portable unit inside a vehicle will experience a
significant loss of range.
To enable the KEYBOARD LOCK press and hold the "ENTER" button for 2 seconds. The display
will contain a key symbol (9). PTT, MON and CALL buttons will still be active. The "ENTER"
button will also activate the backlight for 5 seconds. When radio is in lock mode and any other
keys are pressed a tone will be heard. To disable the KEYBOARD LOCK, press and hold the
"ENTER" button for about 2 seconds.
