amplifier pass all on board diagnostics, it the LED on the pushbutton will illuminate green or
red dependant on previous operating state. Refer to Table 5-1 for ON/OFF push button

There are two methods to shutting down the unit using the On/Off push button. The first
method is to press and hold the push button for five seconds. The second method is to push the
button and the operator will be prompted “Shut down now?” Yes or No. Use the arrow keys to
make a selection and press enter to confirm. To prevent, accidental loss of carrier, if the
amplifier is in transmit mode, the amplifier will query the user on the front panel, if the
intention is to shut down the amplifier.
