Operating Features - Kenwood TK-885 Service Manual

4. INSTALLATION PLANNING – CONTROL STATIONS
4-1. Antenna system
Control station. The antenna system selection depends
on many factors and is beyond the scope of this manual.
Your KENWOOD dealer can help you select an antenna sys-
tem that will best serve your particular needs.
4-2. Radio location
Select a convenient location for your control station radio
which is as close as practical to the antenna cable entry
point. Secondly, use your system's power supply (which
supplies the voltage and current required for your system).
Make sure sufficient air can flow around the radio and power
supply to allow adequate cooling.
SERVICE
This radio is designed for easy servicing. Refer to the
schematic diagrams, printed circuit board views, and align-
ment procedures contained in this manual.
Note
When you modify your radio as described in system set-
up, take the following precaution.
The rating of pin 7 (SB) of the accessory connector cable
(KCT-19) on the rear of the radio is 13.6V (0.75A). Insert a 1A
fuse if you use the SB pin for external equipment.
