IMPORTANT!
This manual described the DVR models that are interfaced to the APX Series Mobile
Radios via P25 Interface. The MSU configured for DVRS operation can support up
to two Control Heads.
The P25 DVRS allows Portable Subscriber Units (
PSU
) to be used in areas where only
Mobile Subscriber Unit (
MSU
) coverage is available and portable radio coverage is either
intermittent or completely absent. Installed in the trunk of a car, fire truck, armored vehicle,
ambulance, the P25 DVRS extends radio communications to the PSU users who are
outside of the vehicle, inside a nearby building or in any marginal portable radio coverage
areas. The DVRS extends voice (analog or digital, clear or encrypted) communications
and supports key Trunking system features. The DVRS can be configured to provide
various advanced options to the users.
