5 INTRODUCTION
The P7200 series radios are dual-band multi-mode portable radios. The P7200 series radio is available
without a front mounted keypad (P7230 Select model -
Figure 5-1), with a 6-buttoned front mounted
keypad (P7250 Scan model -
Figure 5-2) and with a DTMF front mounted keypad (P7270 System model -
Figure 5-3). The dual-band (700/800 MHz) P7200 portable radio delivers end-to-end encrypted digital
voice and IP data communications. It is designed to support multiple operating modes including:
OpenSky
®
Trunked mode (OTP)
EDACS
®
or ProVoice
Trunked mode
P25 Trunked mode
P25 Digital Conventional mode
Conventional Analog mode
The P7200 portables can include all of these modes or just one. Additional modes of operation can be
added with software updates.
The P7200 supports a full range of advanced digital trunking features, including voice group calls,
priority scanning, emergency calls, late call entry, and dynamic reconfiguration. It performs autonomous
roaming for wide area applications. High quality voice coding and robust audio components assure
speech clarity.
In the trunked modes, the user selects a communications “operating” system (i.e., OpenSky, EDACS,
ProVoice, or P25) and group. While communicating in a trunked mode, channel selection is transparent to
the user and is controlled via digital communication with the system controller (e.g. base station in an
OpenSky system or a CSD in an EDACS system). This provides advanced programmable features and
fast access to communication channels.
In Conventional Analog mode, the user selects a channel and communicates directly on that channel. In
this mode, a system refers to a set of channels. A channel is a transmit/receive radio frequency pair.
The exact operation of the radio will depend on the operating mode, the radio’s programming, and the
particular radio system. Most features described in this manual can be enabled through programming.
Consult your System Administrator for the particular features programmed into your P7200.
For further detail about features and operation refer to the appropriate maintenance manual or contact
your System Administrator.
