Turning OFF the DVRS

Deactivating the DVRS via the MSU Control Head

Do the following:

Execute single presses of the VRS Menu Item (Softkey) until OFF Mode is displayed
OR

Select a 'DVR Disabled' TG / Mode / Zone
OR

Power down the MSU if radio operation is no longer required.

Deactivating the DVRS via Call Alert sent by Dispatch

There are two methods for Dispatcher initiated DVRS mode change depending on the
MSU and DVRS programming.
If remote mode change is enabled in the MSU & System Console, the DVRS mode can
be switched remotely when the Dispatcher sends a Call Alert (Page) to a specific MSU
(using the MSU ID). The use of this feature assumes that the Call Alert (Page) function
is disabled in all other subscriber units and reserved for Dispatcher use only in order to
prevent random switching of the DVRS mode during unit-to-unit Call Alert. Switching
OFF an active DVRS may compromise the safety of the PSU users currently relying on
radio communications through this DVRS.
The recommended method is to have the remote mode change disabled in the MSU and
the DVRS can then be programmed with the console Unit ID (or range of IDs) and only
pages of those unit IDs when received by the MSU will cause DVRS mode toggle. This
way the call alert feature can be used in the rest of the system subscriber units without
any danger of unintentionally switching a DVRS mode.
In both cases, Dispatcher sends a Call Alert (Page) to a specific MSU ID, which in turn
causes DVR mode change in the following order: OFF-SYS-LOC-OFF with each
received Page.
The DVRS sends status updates to the Fixed Network Equipment System for each
mode change (P25 Trunking systems only!).
The status updates are sent in the following format:
Status 1 = OFF mode
Status 2 = LOCAL mode
Status 3 = SYSTEM mode
Dispatcher cannot force a Non-Primary DVR to become a Primary and cannot activate a
DVR when a 'VR Disabled' mode is selected on the control head.
