Environment

PCU 7700 MIP

Cause

RAM memory may need to be cleared.

Resolution

To clear RAM memory on the MIP card:

  1. Disconnect Power (failure to do so will permanently damage the device)
  2. Determine how many RAM chips are on the MIP card
  3. Each RAM chip has a corresponding Capacitor. C4, C5 and C6 ( you can have up to 3 RAM chips)
  4. Short across each capacitor 1 at a time
  5. Reconnect power
