15BASIC OPERATION3 Receivingq Set the audio level.➥ Push [MONI•DTMF] to open the squelch.➥ Rotate [VOL] to adjust the audio level.➥ Push [MONI•DTMF] to close the squelch.w Set the squelch level.➥ Rotate [SQL] fully counterclockwise in advance, then ro-tate [SQL] clockwise until the noise just disappears.• When interference is received, rotate [SQL] clockwise againfor attenuator operation. (p. 16)e Set the operating frequency. (pgs. 11, 12)rWhen receiving a signal on the set frequency, squelchopens and the transceiver emits audio.• “BUSY” appears and the S/RFindicator shows the relativesignal strength for the re-ceived signal.✔CONVENIENT!The audio and squelch level can also be adjustedwith [ VOLY(TONE-1)]/[ VOLZ 0(TONE-2)] and[SQLY D(MUTE)]/[ SQLZ #(16KEY-L)], respectively.• “VOL” for audio or “SQL” for squelch appears during set. Monitor functionThis function is used to listen to weak signals without disturb-ing the squelch setting.➥ Push [MONI•DTMF] to open the squelch.• “BUSY” blinks.• Push [MONI•DTMF] again to cancel the function.➥ Push [MONI 1(BANK)] to open the squelch.• Push [MONI 1(BANK)] again to cancel the function.NOTE: When [SQL] adjustment is set too far clockwise,(12–17 o’clock position) the squelch attenuator is acti-vated. To monitor weak signals on the operating frequency,deactivate the squelch attenuator function.
