2.3 BEFORE TURNING THE AMPLIFIER ON
From the Main Menu, the status of the amplifier is displayed and shows if the amplifier is ready for operation.
Status legends, when lit, such as the INTK (INTERLOCK), usually signify OK conditions and that the transmitter is
ready to be turned ON.
Check that all of the following conditions are met:
1. EXCITER or Channel Processor is Ready.
• Usually in the application of AC, the Exciter goes through its warm-up sequence. Ensure that it
has done so.
2. POWER METERING is at Zero.
• On the LCD (see Main Menu display in
Figure 7), the PWR should be at 000% and the STATUS
should be TX IS OFF, NORMALLY.
3. MXi CONTROLLER is ready.
• If there were prior faults, clear them by pushing the RESET button.
4. INTERLOCKS are closed or OK.
• Interlocks and Status are OK.
