■ Automatic power-off
■ 200 programmable memorized channels, identied by editing name.
■ Programming different CTCSS, DCS, 2Tone, 5Tone in per channel, rejecting extra
calling from other radios.
■ Different bandwidth per channel, 25K for wide band, 20K for middle band, or
12.5K for narrow band.
■ Five programmable multi-functional keys, can set various shortcut operation ac
cording to different requirement.
03
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.
1. Install the mounting bracket in the vehicle using the supplied self-tapping screws and
at washers.
2. Position the radio, the 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.
04
■ Determine the appropriate angle of the radio, using the 3 screw hole
positions On the side of the mounting bracket.
DC Power Cable Connection
Note: Locate the power input connector as close to the radio as possible.
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 sufcient current capacity. If the current to the radio
is insufcient the display may darken during transmission or transmitting output power may drop
excessively.
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. Conrm 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.
05
3. Reconnect any writing removed from the negative terminal.
4. Connect the DC power cable to the radio’s power supply connector. Press the connectors rmly
together until the locking tab clicks.
Fixed Station Operation
In order to use this radio for xed station operation you will need a separate 13.8V DC
power supply (not included).
The recommended current capacity of your power supply is 12A.
1. Connect the DC power cable to the regulated DC power supply and ensure that the
polarities are correct. (Red: positive; Black: Negative).
Do not directly the radio to an AC outlet.
Ext. Power jack DC power cable
06
Use the supplied DC power cable to connect the radio to a regulated power
supply. Do not substitute a cable with smaller gauge wires.
2. Connect the radio’s DC power connector to the connector on the DC power cable.
3. Press the connectors rmly together until the locking tab clicks.
Note: Before connecting the DC power to the radio be sure to switch the radio and
the DC power supply OFF.
Do not plug the DC power supply into an AC outlet until you make all connections.

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 your Rugged Radios for assistance.
Only use fuses of the specied 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
sufcient reserves to start the vehicle. Avoid using the radio in these conditions.
08
Antenna Connection
Before operating, install an efcient 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 antenna
to the radio via feed-lines having a impedance other than 50Ω reduces the efciency of
the antenna system and can cause interference to nearby broadcast TV receivers, radio
receivers and other electronic equipment.
Rugged Radios Models/Option
• #DB-RM - Dual Band Mobile Antenna
• #WB-1/4W - UHF/VHF Wide Band 1/4 Wave Antenna (140-470mhz)
• #UNI-MAG - Universal NMO Antenna Mount
• #NMO-MT-U - 13’ NMO Cable Mount (3/8 Thread)
Note: Transmitting without rst connecting an antenna or other matched load may
damage the radio.
Always connect the antenna to the radio before transmitting. All xed stations should
be equipped with a lightning arrester to reduce the risk of re, electric shock and radio
damage.
09
Accessories Connections
External Speaker
If you plan to use an external speaker, choose a speaker with an impedance of 8Ω. The
external speaker jack accepts a 3.5mm mono (2-conductor) plug.
Note: External speaker output adopts double port BTL. Please be aware that the speaker
can’t connect to the ground otherwise the speaker will fault. The wrong connection
way is as below:

Microphone:
For voice communications, connect a microphone equipped insert into the modular socket
on the side of the main unit and tighten the screw. Attach the supplied microphone hanger
in an appropriate location using the screws includes included in the screw set
NOTE: If you plan on using a intercom, disconnect the hand microphone.
