regulated equipment. Maxon subscribes to the same safety
standard for the use of its products. Proper operation of this
radio will result in user exposure far below the Occupa-

WARNING - DO NOT hold the radio in such a manner
that the antenna is next to, or touching, exposed parts of
the body, especially the face or eyes, while transmitting.
WARNING - DO NOT allow children to operate any
transmitter-equipped radio equipment.
CAUTION - DO NOT operate the radio near unshielded
electrical blasting caps or in an explosive atmosphere
unless it is a type specifically designed and qualified for
such use.
CAUTION - DO NOT press and hold the transmit switch
(P-T-T button) when not actually wishing to transmit.
NOTE: This radio operates in FCC regulated frequency
bands. All radios must be licensed by the FCC before use.
Because this radio contains a transmitter, Federal law
prohibits unauthorized use or adjustments of this radio.

Battery Charging and Care
The Ni-Cad battery pack must be fully charged (or new
Alkaline batteries inserted into the alkaline battery pack
shell) to obtain maximum performance from your radio.
A desktop charger is provided with the GMRS-21X radio.
You can charge the provided Ni-Cad battery pack while
attached to the radio in the front charging slot, or the
Ni-Cad battery alone in the rear charging slot. The charging
cycle is overnight (12-16 hours). While charging in either
slot a solid red LED will appear on the charger base.
NOTE: Charge only the provided Ni-Cad battery pack.
To receive maximum performance from your radio and
Ni-Cad battery, periodically discharge the pack completely
and then recharge it.
Antenna Installation
Fasten the antenna to the radio by turning the antenna
clockwise into the receptacle on top of the radio until
firmly seated. Do not overtighten.
Installing and Removing a Battery Pack
To load fresh Alkaline batteries into the alkaline battery
shell, slide the internal holding clip toward the end of the
shell and remove it. Load 4 new "AA" Alkaline batteries,
following the polarity diagram embossed in the shell base.
Realign the holding clip along the shell sides and reposi-
tion to hold the batteries securely.

Installing and Removing a Battery Pack, Continued
To install the Alkaline or Ni-Cad battery pack, hold the
radio face down in one hand; the battery pack (flat side
up) in the other. Orient the battery so that the 2 metal
battery contacts are toward the bottom of the pack. Locate
the tab at battery top and the slot at radio top panel. Turn
the battery pack over in your hand, and tilt the tab end
slightly downward to insert it into the slot. Lower opposite
end of battery toward radio and press firmly until a click
is heard and battery pack is firmly seated.
To remove either pack from the radio, hold the radio face
down in one hand and use the thumb of other hand to
press and hold the battery latch (at the battery pack base).
Use gentle upward pressure to raise the battery about 1/2"
from the radio back. Lift and pull the battery pack away
from the radio, being careful not to break or put pressure
on the battery pack tab.
Attaching and Removing the Belt Clip
The belt clip attaches to the upper right corner of the radio
back. To attach, position the belt clip so that the deep
slotted area faces the holder on radio back. Insert the
holder into the slot, and slide the belt clip upward. A click
will be heard, confirming the belt clip is firmly seated on
the holder. Open belt clip (by pressing top of clip) and
attach to belt, pocket or other convenient location.
To remove the belt clip, simply push and hold the release
button (located at the top of the belt clip) while sliding the
belt clip down off the holder on radio back.

Radio Maintenance/Service
Your GMRS-21X radio is designed to be maintenance free.
To keep your radio in good working condition:
Clean external surfaces with a clean cloth dampened

leaking into cracks and crevices. Do not submerge the
radio. Use a non-metallic brush to dislodge stubborn
particles, if necessary. Dry the surface thoroughly with
a soft, lint free cloth.
DO NOT use solvents or spirits for cleaning - they may
permanently damage the housing.
Clean the radio battery contacts with a lint free cloth to
remove dirt, grease, or other foreign material that may
impede good electrical contact.
DO NOT tamper with internal adjustments. Damage
to the equipment and/or improper operation may
result. There are no user serviceable items inside the
radio.
