programmed to sound “DVR Active”
Tones in the MSU Speaker. This

MSU Mic call
Repeat in LOC
Mode
Enable /
Disable
check box
When the DVRS is in the LOCAL
mode, this setting determines if
MSU Mic calls are repeated by the
DVRS to the Local PSUs (when
Enabled) or not (when Disabled).
This option is related to ‘MSU
System PTT in Local Mode’ option
in the MSU CPS which enables
MSU Mic call repeat to system
while DVRS is in LOCAL mode.
Typically in LOCAL mode Mic calls
are repeated only to Local PSUs by
disabling ‘MSU System PTT in
Local Mode’ and enabling ‘MSU
Mic Call Local Repeat in LOC
Mode’ option.
Warning:
if both options are
disabled, functionality of the MSU
microphone in LOCAL mode will be
disabled
In single DVRS user applications
this option could be used to
disable local repeat and prevent
audio feedback from MSU Mic
and LPSU when the user is
inside the vehicle.
If ‘MSU System PTT in Local
Mode’ option in MSU is enabled,
MIC audio is transmitted to
system.

check box.
When the DVRS is in the SYSTEM
mode, this setting determines if
MSU Mic calls are repeated by the
DVRS to the Local PSUs.
When disabled (unchecked) the
DVRS does not transmit Mic audio
to the LPSUs when the MSU Mic is
PTT-ed and the DVRS is in the
SYSTEM mode.
When enabled (checked), MSU Mic
call audio is transmitted by both the
MSU and the DVR when the DVR
is
in SYSTEM Mode. This is default
option for DVR.
In single DVR user applications
this option could be used to
disable local repeat and prevent
audio feedback from MSU Mic
and LPSU when the user is
inside the vehicle.
DVR Activation

Enable /
Disable
check box.
Enables / Disables the DVR
activation by changing the selected
MSU Mode. If disabled and the
DVR is in OFF mode, changing the
MSU selection to a new mode
programmed for SYSTEM or
LOCAL will not cause any change
to the DVR mode (DVR stays
OFF). If enabled and the MSU
mode is changed to a new one
programmed for SYSTEM or
LOCAL then the DVR will switch
from OFF to SYSTEM or LOCAL
respectively.
