amplifier.
3.7.3 TEMP. FAULT Indicator
Lights at an internal temperature exceeding 80º C with the amplifier
turning off DC bias voltage to the main amplifiers’ modules. DC bias

WARNING!
In the event of ANY power failure, whenever possible and practical, it is
advisable to reset the ON/OFF switch on the front panel to the “OFF”
position before you reconnect AC power to the power amplifier. This is to
prevent any possible electrical damage to the amplifier, due to the initial
power surge, once power is restored.
Turn off the RF power amplifier by first lowering or removing the RF Input drive
level and then placing the ON/OFF switch in the ‘OFF’ position.
