■ receive frequency
■ Rx subaudible signalling value (leave as “None”)
■ squelch setting
■ bandwidth.
6. Open the key settings form and select the required function for each
function key.
For example:
■ FN1 = Preset Channel (same as transmitter)
■ FN2 = Preset Channel (same as transmitter)
■ FN3 = Preset Channel (same as transmitter)
■ FN4 = Monitor / Squelch override
7. Program the receiver.
7.3.6 Receiver Audio Level Adjustment
Unbalanced Line 1. Connect the unbalanced output from the CTU to the audio input
port on the test set and set up the test set to measure the audio level.
2. Set the RF signal generator to the correct RF frequency, modulated
with a 1kHz audio tone at 60% of full system deviation.
3. Set the RF output level to -70dBm.
4. Verify that the receiver gate opens and the busy LED turns on.
5. Adjust RV502 (UNBAL OUT) on the rear panel to set the
unbalanced output to the required level (typically 1Vp-p).
Balanced Line 1. Connect the line output from the CTU to the audio input port on
the test set and set up the test set to measure the audio level.
2. Turn the CTU 600 ohm switch on.
3. Set the RF signal generator to the correct RF frequency modulated
with a 1kHz audio tone at 60% of full system deviation.
4. Set the RF output level to -70dBm.
5. Verify that the receiver gate opens and the busy LED turns on.
6. Adjust RV503 (BAL OUT) on the rear panel to set the balanced
output to the required level (typically -10dBm).
