P25 Digital Vehicular Repeater System
Motorola Solutions offers an MSI Certified APX compatible, third party, P25 Digital Vehicular Repeater
System (DVRS) that provides low-cost portable radio coverage in areas where only mobile radio
coverage is available and portable radio coverage is either intermittent or non-existent.
NOTICE:
Portable subscriber units enabled in the system for Radio Authentication shall be able
to authenticate regardless of whether they are communicating directly on the system or by
using a DVRS.
DVRS can also work with SmartConnect to use broadband coverage for the in-vehicle mobile. Portable
radios communicate through the in-vehicle mobile to the system through the LTE, Satellite or Wi-Fi
connection. This extends the system coverage when you are away from the vehicle.

Conventional Talkgroup and Radio Scan Enhancements
Enhancements have been made to the Conventional Talkgroup at the system to improve the Scan
feature operation significantly when multiple agencies are using a single conventional radio frequency
channel.
These enhancements allow you to use Selective Squelch to operate on only the subset of talkgroups
that are relevant to the users rather than all talkgroups on the channel.
The enhancements support the following Scan mode:
• Mixed Vote Scan.
• Standard Conventional Scan.
• Priority Operation.
Up to 30 different talkgroups can be supported using conventional channels. A maximum of four
talkgroups can be supported when Vote Scan channels are being used.
Smart PTT is supported with this enhancement as Smart PTT prevents you from transmitting while
other users are on the channel.
NOTICE:
User Selectable Talkgroups are not compatible with this Conventional Talkgroup
Enhancement.

What Your Dealer/System Administrator Can Tell You
If the radio is to be operated in extreme temperatures (less than -30 °C or more than +60 °C), check
with your system administrator for the correct radio settings.
You can consult your dealer or system administrator about the following:
• Is your radio programmed with any preset conventional channels?
• Which buttons have been programmed to access other features?
• What optional accessories may suit your needs?
NOTICE:
Specifications may vary for different radio models. Contact your system administrator
for more information.
