- Page 2 of 2 -
The readings on each of the individual UHF Amplifier Trays may not be the same. Refer to the Test Data Sheet for your
Transmitter and compare the final readings from the Factory on the Test Data Sheet with the readings on each of the Trays
after the Set Up. They should be very close to the same. If a reading is way off, refer to the Phasing and Power Adjustment
Procedure for the UHF Amplifier Trays in the Detailed Alignment Procedure before trying to adjust.
If a dummy load is connected to the Transmitter, switch the Transmitter to Standby and switch Off the Main AC Circuit
Breakers found on the AC Distribution Panels in each Cabinet. Remove the dummy load and make all connections needed to
connect the Transmitter to the Antenna for your System. Switch the Main AC Circuit Breakers On and the Operate/Standby
Switch to Operate. Adjust the Exciter Power Adjust pot to attain 100% Combined Output.
If the Transmitter is already connected to the Antenna, check that the Combined Output is 100%. If needed, adjust the Power
Adjust Pot located on the UHF Exciter for 100% in the Combined Output position.
This completes the Transmitter Set-Up and Operation Procedure for the 835A Transmitter. The Transmitter can now be
Operated normally. For Normal operation the Exciter should be in Operate and the Auto/Manual Switch should be in Auto.
If a problem occurred during the Set-Up and Operation Procedure refer to the Detailed Alignment Procedure of the Transmitter
for more information.
