GENERAL OPERATING INSTRUCTIONS
This section covers general operating procedures applicable to all base station configurations. Set
Up and Operating details for specific transceivers can be found in the previous paragraphs.
3.5.1
Preparation for Use
To prepare the transceiver for use (Refer to Figures 1-2, 3-2 and Table 3-2).
(1)
Location for Transmit/Receive Operation.
The VHF frequency band is essentially line of site communication. When selecting an
antenna location there should be no obstacles between the communicating radio sites.
Objects greater than two metres will reflect the RF signal and foliage greatly attenuates
signal strength.
WARNING
Do not make physical contact with antenna when
transmitter is on. This unit can produce up to 30
Watts of power (depending on configuration) when
operated in High Power Mode.
(2)
Install Microphone in Microphone (PTT) connector.
(3)
Ensure that transceiver POWER ON/OFF switch is set to OFF.
(4)
Install AC line cord in AC chassis connector on rear panel and/or install External DC
Cable in External DC chassis connector on rear panel as required.
(5)
Connect antenna connector to rear panel chassis BNC connector.
(6)
For Remote Operation Connect Land Line to DB-9 connector provided on rear of
Base Station.
NOTE
90-6R or 91-DE Series Base Stations are capable of simultaneous local and remote
operation. No switch is provided for exclusive remote or local mode operation.
Refer to previous section and appropriate Operating Instructions for remote use
with a remote DC or tone controller. The following operating procedures are
intended specifically for Local Operation.
(7)
Ensure that the microphone connector is connected to the MIC/PTT connector of
the transceiver.
(8)
Set the SQUELCH control in the fully counter-clockwise (CCW) position.
(9)
