Model: XR Series Transmitter with an Internal or External Antenna

Symptoms

All or some of the below symptoms may be present.

  • Red LED is flashing on the Transmitter front display.

  • Green LED may or may not be illuminated. When the green LED is illuminated, the Transmitter is currently broadcasting (broadcast mode). When the green LED is NOT illuminated, the Transmitter is not broadcasting (standby mode).

  • Transmitter front display does NOT display its GPS communication symbol connection symbol.png, this indicates it's not communicating with the GPS Receiver.

  • Clocks may be displaying a visual signal loss indicator due to they have not received a time update for three days; Analog Clock second hand is stepping and a Digital Clock/Timer colon is flashing.

Problem

Transmitter is not receiving a time update.

Analyze

  1. From the switch panel on the back of the Transmitter, verify switch #1 is set to GPS and switch #2 is set to Local.

  2. Reseat all GPS and cable connections, check to make sure they are not wet or corroded, and look for damage to the cable.

  3. Is there is a GPS extension cable in use? Identity if it's a factory supplied cable or is not factory supplied. If it's not factory supplied, is it longer than 200 ft. and/or is the pin out correct? Step 3 will identify if the extension cable is an issue.

  4. If the GPS communication symbol is not displayed and extension cables are in use, take the GPS Receiver from its location and plug it directly into the back of the Transmitter.

    If the GPS communication symbol appears, the extension cables are the cause of the issue and are required to be replaced. If the GPS communication symbol is not displayed, replace the GPS Receiver as the first step.

  5. If after replacing the GPS Receiver and/or cable and the GPS communication symbol is NOT displayed, the import on the Transmitter may be bad, which will require the Transmitter to be replaced.

  6. Poor power output at the Transmitter can also be the cause of the Transmitter not being able to pull the time update. Complete the steps in Extremely weak or no signal

  7. From the Transmitter front display screen, verify the GPS communication symbol is present, which indicate it's communicating with the GPS Receiver. If the symbol is present, watch for parentheses Three_Parenth.png coming towards the GPS communication symbol which indicates the GPS Receiver unit is receiving a time update from the GPS satellites. If the parentheses are not displayed, complete the steps in Red LED flashing and Transmitter GPS communication symbol displayed, but no parentheses

Solution

  1. If the GPS communication symbol is displayed when direct to the Transmitter, replace the GPS extension cables.

  2. If no GPS communication symbol is displayed when direct to the Transmitter, replace the GPS Receiver.

  3. After replacing all GPS components and the GPS communication symbol is not displayed and the power supply is good, the Transmitter may need to be replaced.
