Going On-Air
IMPORTANT!
Before going on the air, if you want the safety interlocks to operate properly, the
shorting jumpers installed in “Pre-Commissioning Tasks” on page 2.9.2 , Step 4 should be removed.
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 on the transmitter’s ac power.
4. Verify audio input levels using the AUI.
5. Use the local AUI to begin transmitter operations. For detailed instructions, refer to the GV20/GV15
Operating and Maintenance Manual.
 Set for desired power level.
 Press the RF On touch screen button.
 Select the desired exciter as main, if applicable.
WARNING! If a jumper is placed between the INTLK inputs [TB1-1 and 2 on
the remote interface PWB (A16) or pins 19 and 20 of the controller’s (A4)
REMOTE I/O-A connector (A2J5A)], 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.
