RITRON MOBILE RADIO
INSTALLATION GUIDE
Pub. No. 01454928 REV. E 02—02
PREPARATION
Important: THE RITRON MOBILE CAN BE OPERATED ONLY IN
NEGATIVE GROUND ELECTRICAL SYSTEMS! A negative ground system
has the negative (—) battery terminal connected to the vehicle motor block. If
you cannot find this connection, consult the vehicle owner's manual to
determine the ground system type. Most late model U.S. and foreign made
cars and small trucks use a negative ground electrical system. However, some
older cars and newer large trucks use a positive ground system.

MOUNTING LOCATIONS
Before you begin installation, inspect the vehicle and decide how and where
to mount the antenna, radio and microphone. Plan wire and cable runs to
provide maximum protection from pinching and crushing.
•
ANTENNA
Permanent Mount: The best place to mount the antenna is in the center of
a large, flat conductive surface, such as the vehicle's roof. A large trunk lid
also provides a good antenna location. If you use the trunk lid, connect
grounding straps between the trunk lid and vehicle chassis. See the
antenna installation instructions for complete directions.
Glass Mount: Position a glass-mounted antenna as high as possible in the
center of the rear window or windshield. Consult the antenna installation
guide for further instructions.
Magnet Mount: The magnet mounted antenna should be attached to the
center of the vehicle's roof or trunk lid. If you use the trunk lid, connect
grounding straps between the lid and vehicle chassis! Refer to the antenna
installation sheet for details.
•
RADIO MOUNTING BRACKET
The radio mounting bracket permits attaching the mobile to a variety of
surfaces, and requires a flat mounting surface (6" x 2" minimum) with
adequate clearance for inserting the radio. Be certain the mounting surface
can support the radio's weight. Leave enough space around the radio for
air flow cooling, and make sure the user can easily reach and view the
mobile's operating controls and access rear panel connections. The
mounting bracket and radio must not impair vehicle operation. Although the
bracket can be fixed to a plastic dashboard, the mounting screws should
penetrate into the dashboard's supporting metal frame.
•
MICROPHONE HANG-UP CLIP
The microphone clip may be attached to any metal or plastic surface strong
enough to withstand continued microphone use; a hang-up clip to ground
connection is not required.
