Issue 6.1  2021-07-13

5. Connect the dummy load’s interlock or, if necessary, simulate the closing of all 

external interlocks. This requires a short circuit between TB1-1 and TB1-2 and 

between TB1-3 and TB1-4 of the control/interface PWB. 

6. Ensure all networks connected to the transmitter’s RF output are properly covered.

7. In lieu of normal station programming, connect an analog audio generator, preset to 

1000 Hz at zero output (turned off), to XLR connector J12 on the control/interface 

PWB, or an AES signal generator to connector J10 or J11 on the control/interface 

PWB.

WARNING: 

If jumpers are placed between interlock terminals TB1-1/2 and TB1-3/4 

on the control/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.
