LBI-33056 INTRODUCTION The Aegis EDACS M-PA radio is a high quality microprocessor controlled synthesized portable two-way FM radio. The unit complements the Aegis EDACS trunked system by providing a small, rugged, easy to operate and easy to program portable radio for the UHF trunking environment. The radio also provides conventional communications in the UHF spectrum. M-PA operation is highlighted by its programming versatility.
LBI-33056 • Wide Area System Scan Capability - This feature, for multi-site applications, allows the radio to automatically roam from one system to another when the current control channel is lost or on a priority scan timer basis. In the event of a loss of the current system’s control channel. The radio can be programmed to automatically scan for control channels of up to six other systems. If a new control channel is found, the radio will switch to the new system and sound an alert tone.
LBI-33056 when the radio is used in a vehicular charger or repeater. • Emergency Signalling Feature - Pressing a single recessed button instantly sends an alert message on a preprogrammed channel. The radio ID number is transmitted and the unit is given top priority in the system. Emergency signalling can also be enabled by a lanyard connected to the UDC.

LBI-33056 BATTERY PACKS The battery pack connects to the bottom of the unit and delivers a nominal 7.5 Volts dc to the radio. A recessed on/off switch for the radio is located on the battery pack. An internal fuse located in the radio’s Battery Plate protects the radio and battery from excessive current draw. The battery packs are available in several different capacities and sizes.
LBI-33056 PROGRAMMING The radios personality is programmed using an IBM PC or compatible computer. A full-screen portable PC can be used for field programming. The Programming Manual and Software is TQ-3364. This package includes both 5-1/4 floppy and 3-1/2 inch disks. The programming software uses a series of screens and windows to guide you through a programming session. See TQ-3364 for further programming details. PC Programming Adapter TQ-3370 and Programming Cable TQ-3311 will also be required.
