INSTALLATION
Safety and convenience are the primary consideration for mounting any
piece of mobile equipment. All controls must readily available to the opera-
tor without interfering with the movements necessary for safe operation of
the veicle. Set the proper position in the car to install the transceiver using
the supplied supporting bracket or eventually the slide bracket. Tighten the
retaining screws. The fixing bracket must be close to metallic parts.
POWER SUPPLY
Be sure the transceiver is off. In the direct-voltage power supply, is very
important to observe the polarity even if the unit is protected against the
accidental inversion:
Red = positive pole (+)
Black = negative pole (-)
The same colors are present on the battery and in the fuse box of the car.
Correctly connect the cable terminal to the battery.
ATTENTION: To obtain best performances we recommend to install the ra-
dio in a place with enough air circulation.
INSTALLING AN ANTENNA
1. Place the antenna as high as possible.
2. The longer is the antenna, the better will be the performance.
3. If possible, mount the antenna in the center of whatever surface you
choose.
4. Keep antenna cable away from noise sources, such as the ignition switch,
gauges, etc.
5. Make sure you have a solid metal-to-metal ground connection.
6. Prevent cable damage during antenna installation.
WARNING: To avoid damage, never operate your CB radio without connec-
ting a proper antenna. A periodical control of the cable and of the S.W.R. is
recommended.
REPLACING FUSE
If you replace the fuse for DC power Cord, use F 2A 250V type. The parame-
ters and the symbol of the fuse are indicated in the following label.
F2A 250V +
