Analog Output

The headphone source is the analog output of the

receiver. If the receiver is set to Frequency Diversity,

the output signal will consist of the combined audio from

channel 1 and channel 2.

Pre-Tonekey Squelch

The headphone source is taken from a point in the signal

path before processing by Squelch or Frequency Diversity.

This mode is useful for isolating noise or interference that

may be occurring on one of the channels.

To select the headphone source from the receiver menu: Audio > Phones

1. Use the control wheel to select Analog Output or Pre-Tonekey Squelch

2. Press Enter to save changes.

3. Press the monitor volume knob to select the audio from channel 1 or channel 2.

Use the monitor jack located on the front panel of the receiver to monitor the audio output. The signal can be monitored

at two points in the receiver audio chain. Use the Analog Output for normal listening or use Pre-Tonekey Squelch for

troubleshooting. Use the monitor knob to adjust the level.

Note: Mute the RF output by turning the control

wheel past the -30 dB setting.
