Rugged Radios GMR45 User manual

GMR45
USER MANUAL

2
The GMR45 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 which comprise the GMRS channels of the GMR45.
Serious penalties may result from unlicensed use of GMRS channels, in violation of FCC rules,
as stipulated in the Communications Act’s Sections 501 and 502 (amended). You will be
issued a call sign by the FCC that should be used for station identification 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.

• Do not attempt to configure your radio while driving.
• This radio is designed for a 13.8V DC power supply. Do not use a 24V battery to
power on the radio.
• Do not place the transceiver in excessively dusty, humid or wet areas, nor unstable
surfaces.
• Please keep it away from interference devices (Such as TVs, generators, etc.)
• Do not expose the radio to long periods of direct sunlight or place it close to heating
appliances.
• If an abnormal odor or smoke is detected coming from the radio, turn off the power
immediately and contact your dealer.
• Do not transmit with high power for extended periods or the radio may overheat.

1. Install the mounting bracket in the vehicle using the supplied self-tapping screws and
flat washers.
INITIAL INSTALLATION
Mobile Installation: To install the radio select a safe and convenient location inside your vehicle
that minimizes 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.
MOBILE INSTALLATION

8
INITIAL INSTALLATION
• Determine the appropriate angle of the radio using the 3 screw hole positions on the side of the mounting bracket.
• Double check that all screws are tightened to prevent vehicle vibration from loosening the bracket or radio.
2. Position the radio, then insert and tighten the supplied hex/Phillips screws.
MOBILE INSTALLATION (CONT.)

INITIAL INSTALLATION
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 sufficient current capacity. If the
current to the radio is insufficient 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. Confirm 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.

3. Connect the DC power cable to the radio’s power supply connector. Press the
connectors firmly together until the locking tab clicks.

REPLACING FUSES
If the fuse blows, determine the cause then correct the problem. After the problem is
resolved replace the fuse. If newly installed fuses continue to blow, disconnect the power
cable and contact Rugged Radios for assistance. Only use fuses of the specified type and
rating otherwise the radio could be damaged.
Note: If you use the radio for a long period when the vehicle battery is not fully charged
or when the engine is OFF, the battery may become discharged and will not have sufficient
reserves to start the vehicle. Avoid using the radio in these conditions.

ANTENNA CONNECTION
Before operating, install an efficient well-tuned antenna. The success of your installation
will depend largely on the type of antenna and its correct installation. The radio can give
excellent results if the antenna system and its installation are given careful attention. Use a
50Ω impedance antenna and low-loss coaxial feed-line that has a characteristic impedance
of 50Ω, to match the radio input impedance. Coupling the antenna to the radio via feed-lines
having a impedance other than 50Ω reduces the efficiency of the antenna system and can
cause interference to nearby broadcast TV receivers, radio receivers and other electronic
equipment.
Note: Transmitting without first connecting an antenna or other matched load may damage
the radio.
Always connect the antenna to the radio before transmitting. All fixed stations should be
equipped with a lightning arrester to reduce the risk of fire, electric shock and radio damage.

INSTALLING THE ANTENNA
For the best range, only the Rugged Radios GMRS POINT5 antenna should be used. Specific
installation requirements vary between vehicles. Use the following guidelines to install the
antenna. Where you locate your antenna does make a difference!
Important: Mount antenna up high and do not coil-up excess cable.
1. Avoid metal surfaces covered by fiberglass or vinyl that may affect radio range.
2. Mount the antenna as high on the vehicle as possible. The higher the better.
3. If possible, mount the antenna in the center of whatever surface you choose.
4. Be sure the mounting location is clean and dry before installing the antenna.
5. Route the antenna cable through an accessible entry point, such as a door or trunk
opening.
6. When routing the antenna cable inside the vehicle, keep the cable away from noise
sources, such as the ignition system, gauges, etc.
7. Exercise care to prevent cable damage. Make use of existing gaskets, grommets and
weather stripping to protect the cable along its route.

ACCESSORY CONNECTIONS
5-PIN CABLE
