DESCRIPTION

The Ericsson Inc. LPE-200 Portable Radios are rugged,

high-quality, high-performance FM two-way communications unit. It is available in either Scan or System versions. These are Ericsson’s smallest and most sophisticated high-specification portable radios, designed to meet worldwide requirements. They utilize custom designed integrated circuits to set new standards for size and weight for a high power, high specification two way radio. These radios are synthesized and can be programmed to operate on both EDACS® trunked or conventional communications systems. Features include:

Compact Size

Designed small and light with rounded edges to fit comfortably in your hand, while providing specifications and performance superior to larger, heavier radios.

Light Weight, Rugged Constructions

Features a molded case made of a polycarbonate blend surrounding a metal casting. This construction provides a lightweight yet durable housing designed to withstand years of rugged use.

High System/Group Capacity

Both the Scan and the System versions can manage up to 800 different EDACS system/group combinations

with up to 200 conventional channels. EDACS systems/groups can be configured in many different ways to meet specific user needs.

Dual Mode Capability

Conventional operation by simply selecting a pre- programmed conventional system.

Transmit Indicator

A red LED indicator on the top of the radio indicates when the radio is transmitting.

Display

System and group information, status icons and menu operation is supported by the 3-line, 12-character, alphanumeric back lit Liquid Crystal Display (LCD).

Top-Mounted Rotary Knobs

The rugged rotary knobs are designed for ease of operation by allowing tactile access to groups, systems, conventional channels, as well as volume and power control. Knobs are designed with metal protective sleeves which help prevent bent and broken knobs due to impact.

Keypad

The back lit keypad allows the user to access the many radio functions. The 6-button SCAN provides easy access to preprogrammed telephone and individual radio ID’s, while the 15-button System keypad expands this capability, allowing direct entry of these numbers. The LPE-200 radios have a keypad with translucent keys. A detailed description of the keypads and their additional function is found in the OPERATION section.

Emergency ID And Alarm

The user can alert the dispatcher to an emergency by pressing a recessed red button located on the top of the radio which sends user ID and an emergency signal.

Universal Device Connector (UDC)

The UDC provides the PC programmer and optional accessories access to the radio for ease and versatility of radio functionality.

Variable Power Control

PC Programmable from 0.5 to 3 watts

Weatherproof

Radios operate reliably under adverse conditions. These portable radios meet military standards MIL- 810C, D and E specifications for temperature and pressure extremes, solar radiation, driven rain, humidity, salt fog, blowing dust, shock and vibration.

Vibration

Meets EIA, U.S. Forest Service and MIL-810 environmental and vibration-stability requirements.

Personality Programming

Can easily be hooked up to a personal computer in the field, to allow system and radio parameters to be flexibly programmed as requirements change, without changing parts or opening the radio case.
