Going on-air
Important:
Before going on the air, if you want the safety interlocks to operate properly, the shorting
jumpers installed in “Turning on the transmitter” on page 11-3 , Step 3 should be removed.
When the commissioning tests are successfully completed, connect the studio audio to the
transmitter's audio input terminals, connect the RF output to its antenna system, and complete any
emission tests that are required.
1. Turn off the power using the ac disconnect switch, if one is being used, or else at the ac
source.
2. Connect the transmitter's RF output to an antenna system (or verify that the current
connection is intact).
3. Turn the transmitter’s ac power back on.
4. Use the transmitter controls and graphic user interface to begin transmitter operations. For
detailed instructions, refer to the XR6/XR3 Operating and Maintenance Guide.
WARNING:
If a jumper is placed between interlock inputs TB1-1/TB1-2 on the
remote interface pwb, safety features controlled by the external
interlocks will be disabled. A fail safe method of alerting personnel to
this fact should be implemented. Voltages which are dangerous to life
will be present on the RF output stages and the antenna system if the
transmitter is turned on.
