Turning OFF the DVRS
Deactivating the DVRS via the MSU Control Head
To deactivate the DVR via the MSU control head:
•
Press the
DVRS
button to ent
er the ‘DVR Control Mode’, then press the
MODE
button until
VR OFF
is displayed and either press the
SEL
button or wait for the
screen timeout (6 seconds).
OR
•
Select a ‘DVR Disabled’ TG / Mode / Zone on the MSU
OR

Power down the MSU if radio operation is no longer required.
Deactivating the DVRS via Call Alert sent by Dispatch
Dispatcher can send a Call Alert (Page) to a specific MSU ID, which in turn causes DVR
mode change in the following order:
OFF-SYS-LOC-OFF
.
The MSU can be programmed to support one of the following configurations:
a. Call Alert / Remote Activation Disabled
– the MSU does not respond to any Call
Alert requests
b. Call Alert Enabled
– the MSU responds to Call Alerts addressed to its ID and
does NOT initiate DVRS mode change
c. Remote Activation Enabled
– the MSU will acknowledge Call Alerts addressed to
its ID and will initiate DVR mode change provided the source ID of the Call Alert
is pr
ogrammed in the “DVR Remote Activation IDs” table.
If “Generate Status on DVR Mode Change” is enabled for a given DVRS Profile (in the
APX MSU) , the MSU will send back a mode change status to indicate the current DVRS
mode (OFF, SYSTEM, LOCAL). Only the dispatcher console can interpret those status
messages:
DVR MODE
STATUS VALUE
OFF
1
LOCAL
2
SYSTEM
3
Dispatcher can’t force a Non-Primary DVR to become a Primary and can’t activate a
DVR when a ‘VR Disabled’ mode is selected on the control head.
