1.2.5 Crystal Filter Board Assembly P/N 923069-1 (Option 1)
The Crystal Filter is a 25 kHz bandpass filter which provides additional selectivity during receive
operation. The filter provides 5 dB (MAX) attenuation of RF signals ± 7.5 kHz from the receive
frequency and 20 dB (MIN) attenuation of RF signals ± 50.0 kHz from the receive carrier
frequency. This item is interchangeable in the field. Refer to Paragraph 2.2.5 for replacement
instructions. If no crystal filter option is ordered, jumper board assembly P/N 923074-1 is
installed. P/N 923069-2 will provide 40dB attenuation of RF signals ± 50.0 kHz from the receive
carrier frequency with a 7 dB loss in sensitivity as opposed to a 4 dB loss for the 20 dB filter.
1.3 MODES OF OPERATION
1.3.1 Local/Remote Operation
The Single Channel receiver can be operated in Local or Remote modes.
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, receive audio is routed to the internal
loudspeaker and phone jack located on the front panel.
2. REMOTE OPERATION - In Remote operation, receive audio functions are routed over
land lines to the 600 ohm remote inputs. Receive audio is routed to the internal
loudspeaker and is adjustable by the volume control.
1.3.2 AC and DC Operation
The unit can be operated by external 120/220 VAC or external 13.7 Vdc (24 Vdc Optional).
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
Table 1.2 for details.
DC OPERATION - The unit can be operated from an external DC supply within the range
of 11.5 Vdc to 15.0 Vdc. Note: If optional Module A6 is ordered the unit can be operated
within the supply range of 21.7 to 30.0 Vdc.
