3.4 OPERATING INSTRUCTIONS
NOTE
Refer to appropriate Operating Instructions for
use with Remote Audio Monitoring Unit.
NOTE
The following operating procedures are intended
specifically for Local Operation.
(1)
Set the SQUELCH control in the fully counter-clockwise (CCW) position.
(2) Set the VOLUME control in the 12 o'clock centre position.
(3) Set the POWER ON/OFF switch to "ON".
(4) Verify that the FUSE BLOWN red LED is OFF.
(5) Verify that the POWER ON green LED is ON.
(6) Proceed to operate in the receive mode, paragraph 3.4.1 as required.
3.4.1 Receiver Operation (Local Mode)
To operate the receiver in the receive mode, proceed as follows:
(1)
Verify that the correct operating frequency is indicated on the front panel. Refer to
Section 2 for Channel/Frequency selection.
(2) Adjust the SQUELCH control to suit local reception conditions. When the SQUELCH
control is rotated in the counter-clockwise direction, the SQUELCH indicator green LED
will switch to ON, indicating that the squelch circuit is connecting the demodulated audio
output to the VOLUME control.
Further adjustment of the SQUELCH control determines the squelch setting.
IMPORTANT NOTE
The dual conversion receiver’s squelch knob must be rotated significantly more clockwise
(4 o’clock position) to obtain the same squelch setting (3uV) as a single conversion
receiver’s squelch knob set to the 12 o’clock (straight up) position.
If the dual conversion receiver’s squelch knob is set to the 12 o’clock position, signals
with a level greater than 0.5uV will open the squelch. At most airports this will not be an
adequate level of squelch.
