GMRS/FRS RADIO 21-1904
June 11, 2003
INTRODUCTION
Your GMRS/FRS radio is a portable, easy-to-use, two-way radio that you can carry almost
anywhere. Use it to contact family and friends at shopping malls, amusement parks, sports events,
or at the beach to, or for making vital communications in a neighborhood watch.
Your radio has 22 GMRS/FRS channels, 38 CTCSS codes and 10 NOAA weather channels. If
someone else is using the same channel as you selected but you do not want to hear that person,
select another channel or use the CTCSS feature. You can talk with a person who has a
GMRS/FRS radio if both radios are tuned to the same channel and CTCSS code.
Your radio has auto-squelch, which means you will not hear anything on a channel unless
someone is transmitting nearby the same channel. You can turn off auto-squelch to hear weaker
and more distant transmissions.
Also, if the radio is idle for 30, 60 or 90 minutes, it will automatically shut off. It can be wakened
up when you press any key.
You can connect an optional speaker/microphone and earphone, charger (not supplied) to the radio.
In addition, the belt clip on the back of the radio makes you take it very conveniently, you can
carry it almost anywhere.

authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal
Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for
hand-held wireless devices.
CAUTION:
To maintain compliance with the FCC’s RF exposure guidelines, you should hold the transmitter
and antenna at least 2 inch (5 centimeters) from your face and speak in normal voice, with the
antenna pointed up and away from the face. If you wear the handset on your body while using the
headset accessory, only the supplied belt clip for this product can be used, and when transmitting,
take it out of the belt to ensure that the antenna is at least 1 inch (2.5 centimeters) from you body.
Only the supplied antenna can be used, any unauthorized antennas, modifications, or attachments
could damage the transmitter and may violate FCC regulations.
