13. Troubleshooting
This chapter describes the more common operational issues with possible solutions.
Contact technical support if your situation is not described and you need further
assistance.
WARNING
The high*voltage output and cable sheath may be at 300V AC or
450V DC. Be extremely careful when troubleshooting an energized
transmitter.
Issue Possible solution
The cable sheath has
no signal.
• Verify that the transmitter is in Active mode.
• Verify that the programmed setting was not changed.
• Verify that the output is designated for the correct
line (East or West).
• Turn the rear power switch off and carefully check
the rear panel connections.
• Verify that the external relays for the signal protection
and ground control unit are energized.
• Inspect the cable splice box to see if there is a signal
on both sides of the splices. If not found, the problem
might be in the splice area.
The hand-held display
unit is blank.
• Touch the screen to resume. After three minutes of

• Verify that the rear power switch is turned on.
• Verify that the input cord is fully connected.
• Verify that the AC or DC power source is working.
