FCC NOTICE
The GMR25 operates on GMRS (General Mobile Radio Service) frequencies, which require a Federal
Communications Commission (FCC) license. You must be licensed prior to operating on channels 1-7,
15-22 or RP15-22, and RUGGED which comprise the GMRS channels of the GMR25. Serious penalties
may result from unlicensed use of GMRS channels, in violation of FCC rules, as stipulated in the Commu-
nications Act’s Sections 501 and 502 (amended). You will be issued a call sign by the FCC that should be
used for station identication when operating your radio on GMRS channels. You should also cooperate
by engaging in permissible transmissions only, avoiding channel interference with other GMRS users, and
being prudent with the length of your transmission time
To obtain a license or ask questions about the license application, contact the FCC at 1-888-CALL FCC or
go to the FCC’s website: http:// www.fcc.gov and request form 605.

Initial Installation
Mobile Installation
To install the radio select a safe and convenient location inside your vehicle that min-
imizes danger to your passengers and yourself while the vehicle is in motion. Consider
installing the unit at an appropriate position so that knees or legs will not strike it during
sudden braking of your vehicle. Try to pick a well ventilated location that is shielded from
direct sunlight.
CAUTION: Extreme care should be exercised when drilling into dash to avoid damage to
under dash components.
1. Install the mounting bracket in the vehicle using the supplied self-tapping screws and
at washers.
2. Position the radio, then insert and tighten the supplied hex/Phillips screws.
■ Double check that all screws are tightened to prevent vehicle vibration from
loosening the bracket or radio.

■ Determine the appropriate angle of the radio, using the 3 screw hole
positions On the side of the mounting bracket.
DC Power Cable Connection
The vehicle battery must have a nominal rating of 12V. Never connect the radio to a 24V battery.
Be sure to use a 12V vehicle battery that has sufcient current capacity. If the current to the radio
is insufcient the display may darken during transmission or transmitting output power may drop
dramatically.
1. Route the DC power cable supplied with the radio directly to the vehicle’s battery terminals
using the shortest path from the radio. We suggest you do not use the cigarette lighter socket
as some cigarette lighter sockets introduce an unacceptable voltage drop. The entire length of
the cable must be dressed so it is isolated from heat, moisture and the engine secondary (high
voltage) ignition system/cables.
2. Conrm the correct polarity of the connections, then attach the power cable to the battery
terminals: Red connects to the positive (+) terminal and black connects to the negative (-)
terminal.
