The transceiver switches OFF automatically if no keys or 
controls are pressed or adjusted for the selected duration.  
One minute before the transceiver switches OFF, warning 
beeps sound for a few seconds and “APO” blinks.

You can select the APO time from OFF (disable), 30, 60, 
90, 120, or 180 minutes.

  APO continues to count even while the transceiver is scanning.

  The APO timer starts counting down the time when no key 

presses, no control adjustments, and no PC control command 
sequences are detected.

◆

  The APO warning beep sounds even if Menu No. 24 (BP) 

{page 55} is set to “OFF” or the volume level is 0.

Since the transceiver uses a microprocessor to control 
various functions of the transceiver, the CPU clock 
oscillator’s harmonics or image may appear on some 
spots of the reception frequencies.  In this case, turn the 
Beat Shift function ON.

S-meter Squelch causes the squelch to open only when 
a signal with a strength greater than or the same as the 
S-meter setting is received.  This function relieves you 
from constantly resetting the squelch when receiving 
weak stations you have no interest in.
