SECTION 1 - GENERAL INFORMATION
INTRODUCTION
Figure 1.1 The SRP8010, SRP8020/21 and SRP8030/31 Portable Radios
The SRP8000 Series is an advanced portable radio for use in hand-held and body-worn
applications. It provides two main types of signalling operation:
Conventional operation (SRP8010, SRP8020 and SRP8030) offering CTCSS and DTMF signalling
and channel scanning.
Trunked operation (SRP8021 and SRP8031) supporting operation on MPT1327 based trunking
systems.
There are five variants of the SRP8000 Series radio:
Basic SRP8010 With PTT switch, On/Off/Volume control knob, channel change key, one other
programmable key* and four LEDs to indicate the channel in use.
* When one channel only is programmed, two programmable keys are
available.
Simple SRP8020 With PTT and Alarm switches, On/Off/Volume control knob, two other keys, an
LCD display and four keys associated with the display.
SRP8021 A trunked version of the SRP8020.
Complex SRP8030 The same controls as the Simple variant with an additional 12-key numeric
keypad.
SRP8031 A trunked version of the SRP8030.
All variants have a single interface for use with external ancillaries and tools. A coaxial RF connector
is provided for the antenna connection.
Operation of the SRP8000 Series is controlled by settings of the various software parameters.
These operating parameters are stored as data in Flash EPROM and these data may be programmed into
the radio using an external data programmer, allowing the SRP8000 Series to be customized to the
requirements of a particular user.
The SRP8000 Series can use customization data in a user memory plug (UMP), update its
customization data from a UMP, or copy its customization data to a UMP,
The radio is powered from a rechargeable battery unit which attaches to, and forms part of, the
equipment. The battery may either be removed for charging, or be charged whilst still attached to the
equipment, allowing the radio to remain in operation.
