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 1.11.2, Step 3 should be removed (if installed).
1. Turn RF off and remove the jumper from the Interlock connector on the rear panel.
2. Connect the transmitter's RF output to an antenna system (or verify that the current connection is
intact).
3. Re-install the jumper in the Interlock connector and turn RF on.
4. Verify audio input levels using the Front Panel UI.
5. Use the Front Panel UI to begin transmitter operations. For detailed instructions, refer to the VX
Operation and Maintenance Manual.
 Set for desired power level.
 Turn the RF on via the Front Panel UI.
WARNING! If a jumper is placed between the INTLK inputs on the rear
panel of the transmitter, 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.
