Programming The Psus For Dvrs Operation - Futurecom Mobexcom P25 Installation & Programming Manual

If the DVR is in the SYSTEM or LOCAL Mode and the MSU User presses the SCAN
button on the Control Head he /she hears an invalid button press tone and the SCAN
function does not become active.
If the DVR is OFF or Disabled, the MSU User can press the SCAN button and activate
the SCAN function.
Once the MSU is in SCAN:

If the DVR Mode is changed from OFF to SYSTEM or LOCAL, the SCAN is
suspended.

If the DVR Mode is changed back to OFF, the SCAN resumes.
If the MSU is programmed to allow both SCAN and DVR to be activated at the same
time, the following rules apply:

If the MSU lands on a mode which is compatible with the selected DVR channel
then outbound calls are repeated to the Local PSUs.

If the MSU lands on a mode which is not compatible with the selected DVR
channel then the DVR is disabled and the outbound call is not repeated to the
Local PSU.

Inbound call from the Local PSU returns the MSU to the originally selected mode
regardless of the SCAN programming in the MSU.
NOTE:
When SCAN and DVR operation are allowed (by MSU programming), the strapping of
DVR channels to MSU modes must be disabled.
