Remote Activation of another DVR

Permanent Primary Activation

To force a DVR into Permanent Primary Status, press and hold the VRS button for 3
seconds, until "PERM MASTR ON" message appears on the Control Head display and
the Permanent Primary ON/OFF tone is heard in the MSU speaker. The Permanent
V R
Primary Icon will appear on the Control Head Display.
NOTE:
If another Permanent Primary is already present, the newly activated Permanent Primary
DVR will force the "old" Permanent Primary to assume Permanent Primary 'On Standby'
Status. If the Permanent Primary leaves the scene, the Permanent Primary 'On Standby'
takes over. If several Users try to simultaneously activate several DVRS as Permanent
Primaries, the DVRs will go through voting to ensure only one Permanent Primary DVR
is selected and all other DVRs are forced to become Permanent Primaries 'On Standby'.

Permanent Primary Deactivation

Manual change from Permanent Primary to Primary Status can be executed by pressing
and holding the VRS button for 3 seconds on the Control Head until:

The Permanent Primary ON/OFF tone is heard in the MSU speaker and the "PERM
MASTR OFF" message appears momentarily on the Control Head display.

The "Permanent Primary" icon changes to "Primary".

Multiple DVRS Operating on Different DVR Frequencies

If more than one DVRS are present at the same location at the same time and they are
set to operate on different DVR RF Frequencies, the DVRs may operate independently.
For example, DVRS A may be set to operate on DVR CH 1 (F1/F2) and TG X while
DVRS B may be set to DVR CH 2 (F3/F4) and TG Y.
Local PSU User can select DVR CH 1 and talk to TG X Users through DVRS A.
Local PSU User can select DVR CH 2 and talk to TG Y Users through DVRS B.
Both DVRS A and DVRS B will be Primaries i.e. each DVRS will be the Primary on its
selected DVR channel.

Legacy Mobexcom II Voting Compatibility Mode

If Voting Compatibility mode is enabled in the DVR, it can be deployed to operate
alongside Legacy Mobexcom II analog VRs. The voting compatibility mode is applicable
to analog DVRS mode only.
