Look for the letter “L” (Loop Lock Failure) behind the time on the Transmitter front display.
Verify antenna connections and placement.
Internal Antenna: verify antenna connection is not cross threaded and the base of the antenna is flat and secured to the top of the Transmitter case. Verify the antenna is straight up vertically and is not touching anything or extremely close to any metal.
External Antenna: verify connections and inspect external antenna. Verify the antenna and cables running to it are in good shape, cables aren’t bent or kinked, and antenna is not mounted with the head of the antenna near other objects on the roof. Detailed inspection steps provided below.
If power to the Transmitter power supply is bad, resolve the issue.
If the UPS (surge protector/battery backup) is defective, bypass it until the UPS can be replaced.
If power to the Transmitter power supply is good, replace the power supply as your first step.
If there is an “L” behind the time, power cycle the Transmitter, watch it for at least 5 minutes to see if the “L” returns to the screen. If the "L" returns, the Transmitter will need to replaced. If the "L" does not return, advise facility staff to check on it periodically, watching for the “L”. Check the signal and determine how far its reaches.
Internal antenna: relocate Transmitter if antenna issues.
External antenna: replace damaged antennas or antenna cables. Relocate the antenna if there might be antenna issues.
If you have checked all the previous steps and there is still have no signal or it only reaches out less than 100 feet, the Transmitter, antenna or antenna cable may be required to be replaced.
