Symptom:  

Error 779 is being displayed on my PM5.  

Resolution:

This error code is a result of damaged pins inside the RJ45 jack, usually caused by inserting a non-RJ45 plug into this port.

There are two ways to fix this:  

  1. Replace the monitor. If this monitor is being used for racing, we recommend that you replace it.
  2. If this monitor is being used for home use, you can separate the pins inside the RJ45 jacks or continue using the monitor even though the error persists.
