Speak into the microphone and adjust the MICgain control so that the meter deflection does notexceed the ALC zone on voice peaks.Note:Adjustment using the ALC meter provides greateraccuracy than if you try and use the power meter foradjustment. Never adjust for ALC deflection abovethe ALC zone, as this will cause distortion of thetransmitted audio signal.ALC zoneNotes:1. Do not exceed the ALC zone on voice peaks.2.When using high gain microphones or pre-amplified microphones you might have difficultyin obtaining proper ALC meter readings, or youmight receive reports of audio distonion. To pre-vent this type of problem you should set the frontpanel MIC gain control to center and reduce thegain of the internal microphone gain contro}, byrotating the control clockwise, until the properALC reading is obtained. The adjustment of this__ control is described in Section 6-6-6,6. Turn on the PROC switch if required. (Please referto Section 4-3-6)7. Release the PTT switch, or place the standbyswitch to REC.
