DVRS Installation & Programming Guide – PART II
Description
Typically set to 0.38kHz (12.5kHz
channel spacing) or 0.75kHz (25kHz
channel spacing.
PL Squelch Tail Elimination Delay. Must
be set to match the portable setting.
Typical setting is 150ms.
Enables or Disables the Automated VR
Activation (AVRA) Option.
If AVRA is Enabled then this field can
be set to one of the following:
 Once the DVR is ON it can
'Disable'
not be switched OFF via the AVRA
trigger. It can only be switched OFF
from the O5 / O3 / M5 Control Head.
 If the AVRA trigger is de-
'Enable'
asserted, the DVR automatically
switches OFF.
 The DVR is switched OFF
'Toggle'
every second time the AVRA trigger is
de-asserted.
This field must be set to Enabled when
the AVRA trigger is wired up to a VIP
I/P on the O5 / M5 or DEK.
This option enables or disables the
'beep' heard on the MSU speaker upon
DVRS mode change when triggered by
AVRA.
Defines the DVR ON/OFF trigger
polarity when an external switch is
wired to pin 1 of the DB15 connector on
the DVR Auxiliary cable (7W083X06-
01).
When the DC supply voltage drops 0.5V
above the programmed threshold, a
'BATTERY LOW' warning will be
displayed. If the DVR is operating in
Analog Mode it will send warning tones
to the portables over the air. If the
voltage drops below the programmed
level, the DVR is disabled and
'BATTERY LOW' alternates with
ERROR' on the O5 / M5 display and the
VR Transmitter is inhibited.
When the battery voltage reaches 0.8 V
above the programmed level the alarm
condition is reset and the DVR resumes
normal operation.

Notes
Affects Analog Mode only.
Depends on the selected
Channel Spacing – refer to the
Frequency Band Setup
Affects Analog Mode only.
If this field is programmed too
short the squelch tail will not be
fully eliminated. If it is
programmed too long, the
portable may unmute
unnecessarily.
Only applicable if AVRA is
Enabled.
The 'Enable' setting is typically
used when the AVRA trigger is
a Portable charger. Removing
the portable from the charger
switches the DVR ON (System
Mode). Placing the Portable
back in the charger switches
the DVR OFF.
The 'Toggle' setting is typically
used when the AVRA trigger is
a car door switch. Closing the
door the first time does not
deactivate the DVR.
The same 'beep' is heard when
the DVRS mode is changed by
pressing the VRS button on the
control head.
Applicable when the DVR
ON/OFF activation trigger is
wired to the DVR Auxiliary
cable. Not applicable when the
DVR ON/OFF trigger is wired to
the mobile radio CH VIP.
Typical setting is 10V.
