5.3 Normal Operating Procedures
CAUTION! Before starting or operating the amplifier for the first time,
be sure that "Initial Power-On And Checkout" procedures described In
Chapter 3 have been performed.
5.3.1
LOCAL Mode Operation
For normal operation in LOCAL mode, proceed as follows:
a.
b.
c.
d.
e.
NOTE: If high voltage was ON when the unit was shut down (amplifier
was in the XMT state), high voltage will automatically be restored when
the HTD and BONS cycles are complete.
f.
g.
h.

Apply AC power. The power on self tests (POST) start.
Set the amplifier for LOCAL control mode. (Press the
LCL/RMT switch once if the RMT LED is ON.)
Verify that the amplifier FLT LED is not flashing. Refer to
5.6.7 any time the FLT LED flashes.
Verify that the amplifier STBY LED lights after the 3 minute
heater time delay.
Press the HV ON switch once, the amplifier XMT LED flashes
during the Beam On Sequence, and stays ON if BONS was
successful. The amplifier is now in the XMT mode.
Alternate method: press the HV ON switch once during HTD;
this causes the XMT LED to flash (XMIT select mode). BONS
and Transmission of RF will occur automatically at the
completion of HTD.
Ensure that a RF input is applied to RF input J3.
To change to the STBY state, press the HV ON switch once.
(The XMT LED will go off and the STBY LED will light.)
