Sunpentown Intl FM-8800D/8800S Adjusting volume of loudspeaker, Adjusting squelch, Transmitting

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 (Push-to-talk) switch on the handset or microphone to talk, and release it to listen for the response. The VHF section keyboard accepts no key input when the PTT switch is operated.

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.

1.2.6Selecting output power

After pressing the SHIFT key, each press of the 0 HI/LO key selects high or low output power. Also Hi or Lo appears on the screen depending on your selection.

The transmitter power is automatically set for low on the following channels:

International:	CH15, CH17, CH75, CH76
USA:	CH13, CH17, CH67, CH77; to operate USA channel 13 or 67 in
	high power, keep HI/LOW key pressed while talking into the
	handset.
