1. OPERATIONAL OVERVIEW
1.2.3Adjusting volume of loudspeaker
The VOLUME control adjusts the volume of the loudspeaker.
1.2.4Adjusting squelch
The SQUELCH control adjusts the squelch threshold level. Adjust it so that white noise heard in the loudspeaker just fades out. Perform this operation when no traffic is being received. AUTO squelch automatically reduces white noise. Usually select the AUTO position. Avoid turning the squelch too far clockwise — you may miss a long distance communication.
Note: To obtain correct scan watch/dual watch response, adjust the SQUELCH control precisely.
1.2.5Transmitting
Press the PTT
Remarks on transmitting
•Before transmitting, think about the subjects which have to be communicated and, if necessary, prepare written notes to avoid unnecessary interruptions and ensure that no valuable time is wasted on a busy channel.
•Listen before commencing to transmit to make certain that the channel is not already in use.
