AUTOMATIC POWER OFF (APO) Automatic Power Off is a background function that monitors whether or not any operations have been performed (keys pressed, Tuning control turned, etc.), and turns the transceiver power OFF if it has not been in use. 1 Enter Menu mode and access Menu 516 (APO). S-METER SQUELCH S-meter Squelch causes the squelch to open only when a signal with the same or greater strength than the Smeter setting is received. This function relieves you from constantly resetting the squelch when receiving weak stations that you have no interest in. 1 Enter Menu mode and access Menu 105. 2 Set the APO time limit to 30, 60, 90, 120, 180 minutes, or OFF. • After the time limit passes with no operations (default is OFF), APO turns the transceiver power OFF. However, 1 minute before the power turns OFF, "APO" appears on the display and blinks, and a warning tone sounds. 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 on which band you have selected. • The squelch will open only at the level you have selected (for example, level 9). Note: If any settings are changed during while APO is ON, the timer resets. When you stop changing the settings, the timer begins counting again from 0. SWITCHING FM/AM MODE This transceiver is also capable of receiving (not transmitting) in AM on band A. The default mode on the 118 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. ■ Squelch Hang-up Time When using S-meter Squelch, you may want to adjust the time interval between when the received signals drop 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, or OFF. 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. AIP helps eliminate interference and reduce audio distortion caused by inter modulation. You can use this function only 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. OTHER OP-4
