163BASIC OPERATION3 Squelch attenuatorThe transceiver has an RF attenuator related to the squelchlevel setting. Approx. 10 dB attenuation is obtained at maxi-mum setting.The squelch attenuator allows you to set a minimum signallevel needed to open the squelch. The attenuator function canbe deactivated in initial set mode.➥ Rotate [SQL] clockwise past the 12 o’clock position to ac-tivate the squelch attenuator.• Attenuation level can be adjusted up to 10 dB (approx.) between12 o’clock and fully clockwise position.• When setting the squelch from the microphone, a level greaterthan ‘19’ activates the squelch attenuator.NOTE: The squelch attenuator functions even when themonitor function is in use. Thus set [SQL] control within 10to 12 o’clock position is recommended when using themonitor function.D Squelch attenuator settingq Turn the transceiver power OFF.wWhile pushing [SET•LOCK], turn the power ON to enter ini-tial set mode.ePush [SET•LOCK] or [S.MW•MW] to select “ATT” (squelchattenuator) item.r Rotate [DIAL] to toggle the function ON and OFF.• Select “OF” to deactivate the squelch attenuator function.t Push [PWR] to exit initial set mode.[PWR][SET•LOCK]USING INITIAL SET MODESquelch isopen.SquelchattenuatorSquelchthresholdShallow DeepNoise squelch
