1.3 MODES OF OPERATION
1.3.1 Local/Remote Operation
NOTE: Local operation is not disabled when operating in Remote mode and Remote operation is
not disabled when operating in Local mode. The two operating modes operate in parallel.
1. LOCAL OPERATION - In local operation, voice audio, and keying (PTT) functions are
routed from the microphone (not supplied) to the transceiver. Receive audio is routed to
the internal loudspeaker and phone jack located on the front panel.
2. REMOTE OPERATION - In Remote operation, transmit audio, keying (PTT), and receive
audio functions are routed over land lines to the 600 ohm remote inputs. Internal jumpers
can be set for ±DC, ground, or tone transmitter keying, and to provide a DC squelch
signal and RF Output Power signal depending on the remote control board installed.
Receive audio is routed to the internal loudspeaker and is adjustable by the volume
control. Transmit audio is also routed to the internal loudspeaker at an internally
adjustable preset level (see conference audio).
1.3.1.1 Conference Audio (Optional)
NOTE: This feature is only provided upon special order. The component (R7) discussed below is
left unpopulated on standard configuration radios.
Conference Audio provides the operator with Tx voice on the transceiver speaker when the
transmitter is remotely keyed from another location. The audio level of the transmit audio is
internally adjustable from 0.0W to 0.5W of audio output. The adjustment is performed via rotation
of the potentiometer R7 (see Figure 2.5 for location), which is accessible from the top of the
transceiver after removing the top dust cover of the unit.
NOTE: The transmit audio level can be increased by rotating potentiometer R7 clockwise and
decreased by counter clockwise rotation. If further adjustment of conference audio is required, the
top cover of the transceiver module must be removed to gain access to potentiometer R63,
located on the Audio Interface Module, A3 (see Figure 2.5 for location).
1.3.2 AC and DC Operation
The unit can be operated by external 120 VAC or external 28 VDC (13.7 VDC for Low power
configurations). The AC power supply can also be set to allow operation on 240 VAC.
1. AC OPERATION - During AC operation, the unit can charge and trickle charge external
batteries via the external connectors mounted on the rear panel of the unit. Refer to
section 3 for remote connector pin details regarding DC operation.
DC OPERATION - The unit can be operated from an external DC supply within the range
of 21.6 Vdc to 30 Vdc for 15 watt and 25 watt configurations and within the range of 11.5
Vdc to 15.0 Vdc for Low power configurations.
1.4 TECHNICAL SUMMARY
A summary of electrical, operational, mechanical and physical characteristics of the Single
Channel Transceivers are provided in Tables 1.2.
