Battery Reset Switch (SW1)
Normally, the operation of the Low Voltage Disconnect assembly is fully
automatic. The only exception is when replacing a discharged battery with a
charged battery
if AC power has not returned
. In this case, it is necessary to
press the battery reset switch,
SW1
on the Battery Control Board, after
installing the new battery. (See Figure 11.) Use a pen or other pointed object
to press the switch.

4.5 Antenna System
Antenna Installation
The antenna manufacturer’s installation instructions should be followed for
proper operation of the antenna. Using the proper mounting hardware and
bracket ensures a secure mounting arrangement with no pattern distortion or
detuning of the antenna.
Regardless of the antenna make, mount the antenna in the clear, as far away as
possible from obstructions such as buildings, metal objects and dense foliage.
Choose a location that provides a clear path in the direction of the associated
station.
NOTE:
Strong fields near the antenna can interfere with the operation of
low-level circuits and change the values of the data being received.
For this reason, the antenna should be mounted at least 3 meters (10
feet) from the radio and other electronic equipment.
Feedline Installation
A low-loss feedline is recommended for use with the radio. Section 3.2,
Antenna and Feedline Selection
, beginning on page 10 provides suggestions
for choosing the correct feedline for your installation. Whatever cable is used,
it should be kept as short as possible to keep signal losses to a minimum.
When installing the feedline, take care not to kink, twist or stretch the cable.
After installation, fasten the cable securely to the antenna tower or other
supporting structure.
