Operating Modes
It 's designed to support multiple operating modes including:
. MPT Trunked Mode
. DMR/PDT Trunked Mode
. DMR/PDT Digital Conventional Mode
. Conventional Analog Mode
The PD70X/PD70XG portables can include all of these modes.
The PD70X/PD70XG supports a full range of advanced digital trunking features, including talk 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., DMR,PDT,MPT
) 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. 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.
A channel is a transmit/receive radio frequency pair.
The exact operation of the radio will depend on the operating mode, the radio is programming, and the
particular radio system. Most features described in this manual can be enabled through programming.
Then refer to the corresponding section(s) within this manual for feature and operation information.
