3 BASIC OPERATION Setting the squelch level The squelch circuit mutes the received audio signal, depending on the signal strength. 1. Rotate [VOL] to turn OFF the transceiver. 2. Set [Rotary Selector] to any channel other than Channel 16. 3. While holding down [PTT] and [Lower], rotate [VOL] to turn ON the transceiver and enter the squelch level adjustment mode. 4. Push [Upper] to increase the squelch level, or push [Lower] to decrease the squelch level. LLThe adjustable range is between 0 (open) to 9 (tight). •• A beep sounds after pushing [Upper] or [Lower]. An error beep sounds when the adjustable range is exceeded. 5. Rotate [VOL] to turn OFF the transceiver, then turn it ON again to restart normal operation. Selecting the output power level If the transceiver has [High/Low] assigned to it, the transmit output power level can be selected, depending on the presetting. When the battery voltage drops to a low level, and the status indicator status is "Low Battery 2," the output power automatically switches to "Low 1." (p. 2-3) zz Push [High/Low] to select the transmit output power level. •• A beep sounds when "Low 1" is selected. •• Two beeps sound when "Low 2" is selected. •• Three beeps sound when "High" is selected. 3-6
