Model: XR Transmitter

Symptoms

All or some of the below symptoms may be present.

  • Red LED is flashing on the Transmitter front display.

  • Transmitter Diagnostic Menu displays VWSR Errors -indicates there is a problem with either the external antenna or the antenna cabling.

  • 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 might have an antenna or antenna cable issue, or the antenna might be located to close to something in its environment that is causing signal return on the line.

Analyze

Transmitter with an internal antenna:

  1. Verify the antenna is not cross threaded and is down tight to the top of the Transmitter.

  2. Verify the location of the Transmitter does not place the antenna close to metal or wiring that may interfere with the dispersal of the signal or signal return back to the Transmitter.

  3. Verify the location of the Transmitter does not place the antenna close to equipment that may interfere with the dispersal of the signal or signal return back to the Transmitter.

Transmitter with an 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.

  1. Verify the LMR 400 Coaxial Cable connections are secure both at the Transmitter and at the Omni Directional Antenna.

  2. Visually inspect the LMR 400 Coaxial Cable from the back of the Transmitter out to the Omni Directional Antenna - look for any damage (cuts, kinks compressions). If cable is damaged, replace the cable.

  3. Visually inspect the Omni Directional Antenna for a bent radiator (top of the antenna that looks like a trombone slide that wider at the top and tapers at the antenna base). There should be three radials attached to the antenna base at 30 degree angles. Make sure all three radials are attached and securely fastened. Replace any damaged or missing components.

  4. Verify a GelWrap splice closure is in use to protect connection from outdoor elements. Open and inspect the connection to ensure it's secure and has not been not compromised by moisture or corrosion. Dry connection if it’s wet.

  5. Verify the LMR 400 Coaxial Cable is routed and secured with a UV Resistant cable tied to the outside of the antenna mast. Be sure it is NOT routed to the inside of the mast, which may cause the connection to become wet due to condensation from ongoing seasonal climate changes.

  6. Inspect the area where the antenna is installed, make sure the antenna head is well above the roof line and not near obstacles on the roof that could cause the signal to return on the line.

  7. Verify the antenna has 15 ft. of clearance from other antennas and any metal.

Solution

  1. Correct all issues with installation of the antenna.

  2. Internal antenna: relocate the Transmitter into an area where it is clear of any obstacles.

  3. External Antenna: relocate the antenna to an area where it's clear from any obstacles. Replace questionable looking antenna components and cabling.

  4. If after all corrections are performed and the error won’t clear, the Transmitter may need to be replaced.
