5. Set all circuit breakers and switches, including the local incoming AC line
breaker, to the OFF position. Place an appropriate AC power line protector
(surge suppressor) across the AC line that supplies the transmitter.
6. Connect the transmitters AC power line cable to an appropriate fused AC
receptacle.
7. Using an ‘N‘-Type connector, connect the transmitting antenna cable to the
transmitter's RF OUT connector located in the upper middle of the cabinet's
rear panel.
*Connect the optional remote control computer to the transmitter using the data
connector located on the rear of the transmitter cabinet. The computer should
have the supplied software installed and operating on the computer.
1.5 Operation:
Assuming the installation instructions of Section 1.4 have been completed and the
transmitter is receiving an IF input from the modulator, proceed with the following
steps to place the transmitter in operation.
The modulator should be pre-aligned for a Video Input of 1vpp and Audio Input of
0dBm. Verify that the audio and video sources are set to these levels. Adjustment
of the aural level and/or video level controls should only be done using the
maintenance section of this manual by a trained service technician with the proper
test equipment.
The transmitter has been factory aligned for 100 watts visual and 5 watts aural (25
watts average power), with AGC, when the AGC switch is ON. Transmitter power
adjustment using the controls accessed through the front panel should be only
performed according to the maintenance section of this manual and by properly
trained maintenance personnel with the recommended test equipment.
Turn on the two power switches located at the rear of the transmitter. The
transmitter will power up in the configuration selected when power was last applied.
The unit is shipped in a default power off configuration, and requires commands
from the Control Board for full turn-on. In the Standby state, power is only supplied
to the up-converter.
Turn the rear panel AC main power switch to ON, then using the Operate/Standby
switch, turn the transmitter to Operate; power is now applied to all sections of the
transmitter.
