  • Red LED is flashing on the Transmitter front display.

  • Channel Number may be or may not be displayed on the Transmitter front display, located in the lower right hand corner of the screen.

    • Channel Number displayed: indicates the Transmitter is currently broadcasting.

    • Channel Number is NOT displayed: indicates the Transmitter is not currently broadcasting.

  • 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 communicating with the GPS Receiver, but is not receiving a time update from the GPS satellites.

Analyze

  1. Is the GPS Receiver inside? If it’s mounted to a window or mounted where signal has to go through the roof, the GPS Receiver may need to be relocated outdoors. A GPS Receiver located indoors may not allow for an adequate signal. Low-E glass windows are coated with a transparent metal layer that reflects infrared heat rays; which can also reflect the GPS signal.

  2. Check the GPS Receiver mounting location. Verify its mounting did not slip or change and it has a clear view of the sky. Resolve any obstructions.

  3. There may be local interference affecting GPS signal reception. Try moving the location of the GPS Receiver to improve reception. Weather conditions, solar flares, time of day, and exact satellite position may also effect signal reception; however, these conditions are normally of a short duration.

  4. Poor connections of the GPS cables or a faulty GPS Receiver can cause the unit not to pick up a signal. If steps 1 and 2 do not resolve the issue, replace the GPS Receiver and its extension cables.

  5. If the Transmitter has low output power, it may not be able to pull the time update. Check voltage at the Transmitter.

Solution

  1. Move the GPS Receiver into a better location; outdoors with a clear view of the sky.

  2. Replace the GPS Receiver and its extension cables.

  3. After replacing all GPS components and still no parentheses, the Transmitter may need to be replaced.

    If none of the above steps resolved the issue, the import on the Transmitter may be bad and need replacing.
