I can hear an alarm coming from the docking station or terminal.

An alarm indicates that the docking station or terminal has detected a short between the positive and ground of its RF connections (Satellite and GPS).  The short could either be in the unit itself, along the cables, or in the antenna.

If you hear the alarm, remove power immediately to avoid causing more damage to the setup.

To locate which component of the setup is causing the fault, please follow the steps below.  Remember to only apply power briefly and immediately remove power when an alarm is heard.

Check if the short is within the unit:

1. Disconnect the satellite and GPS cable from the unit.
2. Switch the unit on.
3. If the alarm goes away, then the short is along the cable and the antenna path. Proceed to next step 3.
   1. If the alarm is still present, then the short is within the unit. To fix this fault, we require for the unit to be returned to Beam for service.

Check if the short is within the cables:

1. Switch off the unit, connect the satellite and GPS cable to the terminal, disconnect the antenna.
2. Switch on the unit, if the alarm has disappeared, then it is possible there is a short in the antenna. Replace the cable when necessary.
   1. If the alarm is still present, then the short is possibly within the antenna. Proceed to step 5.

Check if the short is within the antenna:

1. Switch off the unit.
2. With the cables connected to the unit, connect the other end of the cables to the antenna.
3. Switch on the unit, if the alarm came back, then the short is within the antenna. Replace the antenna when necessary.
