battery pack provides a nominal 7.5 volts. Two different nickel cadmium battery packs offering high and extended capacities are available for use with the portable radios.

The top of the radio has a Volume, Channel/ Area/System select knob, Emergency/Home button, TX LED and a screw-on antenna mount connector. Located on the front is a 3-line 12 character per line dot matrix LCD with backlighting. A chip-on-glass filtered super twisted nematic LCD with a transflective rear film is used. A 36

mmspeaker and electret microphone are located above the LCD. Below the speaker is either a 6-button keypad for Scan operation or a 15-button keypad for System operation. A push-to-talk bar is located on the left side along with a Clear/Monitor button and option button. On the opposite side a UDC connector is located for plug-in accessories and PC programming.

One printed wire board assembly contains the transmitter/receiver, audio and logic circuitry. A separate printed wire board assembly (daughter board) contains the DSP Module. The radio board assembly is cradled in a zinc die casting which is used as a PA heat sink and for housing rigidity. A sheet metal shield completes the RF shielding.

The keypad and LCD assembly are separate from the main board and interconnect by a flex-circuit. This flex- circuit also interconnects the speaker, microphone and UDC assemblies. Top controls mount to another flex-circuit board that plugs into the main radio board assembly.

Radio circuitry is centered mainly on one radio board. This board is mounted in a metal housing with a metal shield covering the top of the board. This enclosure is penetrated only by a flex cable which ties the front, user interface part of the radio to the board and a 3-pin battery connector. Surface mount components populate both top and bottom of the radio board allowing a combination of both RF and
