OTHER OP-AUTOMATIC POWER Off (APO)Automatic Power Off is a background function thatmonitors whether or not any operations have beenperformed (keys pressed, Tuning control turned, etc.),and turns the transceiver power OFF if it has not been inuse.1 Enter Menu mode and access Menu 516 (APO).2 Set the APO time limit to 30, 60, 90, 120, 180 minutes,or OFF.• After the time limit passes with no operations (default isOFF), APO turns the transceiver power OFF. However, 1minute before the power turns OFF, “APO” appears on thedisplay and blinks, and a warning tone sounds.Note: If any settings are changed during while APO is ON, thetimer resets. When you stop changing the settings, the timer beginscounting again from 0.SWITCHING fM/AM MODEThis transceiver is also capable of receiving (nottransmitting) in AM on band A. The default mode on the118 MHz band is AM while the default on the 144, 220,300, or 430/440 MHz band is FM.1 Enter Menu mode and access Menu 102.2 Set the mode to AM, FM, or NFM.Note: You cannot switch between FM and AM to receive on band B.ADVANCED INTERCEPT POINT (AIP)The VHF/UHF band is often crowded in urban areas. AIPhelps eliminate interference and reduce audio distortioncaused by inter modulation. You can use this functiononly while operating on the VHF/UHF band.1 Enter Menu mode and access Menu 103 (VHF.AIP)and/or Menu 104 (UHF.AIP).2 Set the AIP to ON or OFF.S-METER SqUELCHS-meter Squelch causes the squelch to open only whena signal with the same or greater strength than the S-meter setting is received. This function relieves you fromconstantly resetting the squelch when receiving weakstations that you have no interest in.1 Enter Menu mode and access Menu 105.2 Set the S-Meter squelch to ON or OFF.3 To select the desired S-meter setting, rotate the left(band A) or right (band B) SQL control depending onwhich band you have selected.• The squelch will open only at the level you have selected(for example, level 9).n Squelch Hang-up TimeWhen using S-meter Squelch, you may want to adjustthe time interval between when the received signalsdrop and when the squelch closes.1 Enter Menu mode and access Menu 106.2 Set the hang-up time to 125, 250 or 500 ms, orOFF.
