Transceiver NPM-2NX
Introduction
The NPM-2NX is a dual band radio transceiver unit for GAIT (AMPS/TDMA800/
TDMA1900/GSM1900) networks. It is a true 3 V transceiver with internal antenna and
vibra.
Mechanical construction resembles Nokia 61XX series and the same accessories can be
used. External RF connector is included.
An integrated Infrared link is located on the top of the phone.
NPM-2NX has the connection for the small SIM (Subscribe Identity Module) card.
The PWB has one-sided SMD and there is no separate User Interface PWB but the key-
board connections are on the non-SMD side of the board.
