2.3.1.3. INTK Status LED
Interlock inputs that affect the RF amplifier are all closed and OK. The amplifier Ext1 interlock is the last in the chain
and will only be closed if all the other previous interlocks are also true (these include Vswr, Thermal, TxSw).
 Lit when transmitter is ON and all interlocks are closed (i.e., OK).
 Not lit when the transmitter is either OFF or one of the interlocks are opened.
If the transmitter has indeed been set to ON and the front panel ON LED is lit, an error is present.
The operator should then check the INTK submenu to determine the source of the problem.
2.3.1.4. PSOK Status LED
Power Supply OK status, the 50V power supply to the RF amplifier is currently ON and is operating properly.
 Lit when the Power Supply is ON. The P/S voltage, current and status are all OK.
