To check the buttons and the switches, perform the following tests:
1. Turn radio on.
2. After the self test is complete, press the monitor button (side
button 3, SB3) five times in succession, within 10 seconds. After
the fifth press, a tone is emitted to indicate that the RF test mode
has been entered.
3. Exit the RF test mode and enter the control head test mode by
pressing and holding SB3 for more than three seconds. Upon
entering the control head test mode, a tone is emitted and the
green LED begins flashing. The green LED continues to flash until
the control head test mode is exited.
NOTE: Return to the RF test mode by pressing and
holding SB3 for more than three seconds. Then
re-enter the control head test mode by pressing
and holding SB3 for more than three seconds.
4. Test each switch (toggle, rotary, or button-actuated) by changing
the position of the switch. A tone is emitted to indicate a “good
test” each time a switch position is changed.
NOTE: Pressing and releasing a button-actuated
switch are both considered switch-position
changes.
NOTE: No tone when a switch position is changed
indicates a test failure. Test the on/off volume
potentiometer/switch by rotating the
potentiometer clockwise and counter
