3M Electronic Monitoring offers the new Dual
Comm RF Monitoring System – a multi-clientmonitoring unit that is capable of monitoring
up to 50 client transmitters within the
monitored perimeter. The RF (E4) Receiver
unit also has the capability to manage the
various program schemes, event
configurations, and schedules assigned to
each client.
RF (E4) Receivers are dual communication
units – able to communicate with the central
monitoring computer via landline and/or via
cellular communication. Users can specify
either communication type, or can use both
methods together for redundancy.
The RF (E4) Receiver unit installation is easy, simple, and quick; all one needs is to plug in
the power adapter (and the phone cord when landline communication is being used). The
LCD screen and buttons enable a simple, intuitive installation process, and afterwards, they
enable easy status monitoring.
The unit can start tracking the offender as soon as it is installed (utilizing the default
parameters).

The installation process is completed after the monitoring center’s Data Communication
Computer (DCC) downloads the unit’s parameters (such as curfew schedule, transmitter ID,
call-back phone numbers, settings, etc.) into the RF (E4) Receiver unit's memory, thereby
setting the unit to active monitoring mode. The RF (E4) Receiver internally connects the
backup battery and starts tracking the offender.

Monitoring multiple transmitters
The 3M™ Dual Comm RF Monitoring Receiver is capable of receiving transmissions from
any 3M Electronic Monitoring transmitter. It's ability to communicate with all types of 3M
transmitter enables maximum equipment handling flexibility. The 3M™ Dual Comm RF
Monitoring receiver can store up to 50 offender curfew schedules, and concurrently
monitor up to 50 offenders. The basic unit is supplied with a software license for
monitoring 1 offender; additional monitored offenders are supported depending on the
license purchased.
3.5” color LCD with 5 buttons
The 3M™ Dual Comm RF Monitoring Receiver is
equipped with a 3.5” color LCD and 5 buttons. The
LCD screen and the buttons are used to display
and interact with the Receiver unit’s User
Interface, which includes:
Displaying date and time (synchronized to
each offender's schedule)
Displaying status information (such as cellular
reception indications)
