Operating Manual

5.Adjust the compression level of the Speech Processor via the Menu Item “109 TGEN PROCLVL” so that the meter needle deflects to not more than “10 dB” on the COMP meter scale. See Box at the right for details of the setting.

6.To switch the Speech Processor off, press the [PROC] button once more. The “MIC EQ” and “PROC” icons will turn off, confirming that the Speech processor is turned off.

Advice:

Excessive advancement of the compression gain will result in a degradation of the transmitted signal’s signal-to-noise ratio, thereby reducing intelligibility at the other end of the circuit.

The Transmit Monitor is very helpful way of verifying proper adjustment of the compression level. Pressing the [MONI] button then adjusting the [MONI] knob for a comfortable listening level while you are transmitting, you will be able to hear the difference in sound quality as you make adjustments.

You may set the RF power output via the Menu item “111 TGEN TX PWR”, whether or not the Speech Processor is engaged.

You may adjust the Parametric Microphone Equalizer when the speech processor is engaged, using Menu Items “100” through “108”. See page ?? for details.

When the optional DMU-2000 Data Management Unit is connected, you may observe the effect of your compression level adjustments by viewing the wave-form on the “Oscilloscope” page.

Advice: Press the [SELECT] knob to toggle the Menu item display between “109 TGEN” and “PROCLVL”.

4.Press the PTT switch on the microphone, and speak into the microphone in a normal voice level. Rotate the [CLAR/VFO-B] knob so that the meter deflects to not more than “10 dB” on the COMP meter scale.
