Appendix 1
Foreword
This section of the service manual (Appendix) contains specific details for
the NHN–6NF handportable telephone used on the NMT900 network.
The appendix comprises three chapters as follows: Chapter 1, Foreword
(this chapter); Chapter 2, Transceiver NHN–6NF, containing an exploded
view of the NHN–6NF variant (including a list of assembly parts) plus
component parts lists covering the system module and the display
module; and Chapter 3, Quick Guide, which aims to provide all user
information that service personnel are likely to require during servicing

Transceiver NHN–6NF
Functional Description
The transceiver electronics consist of UI module PCB and RF/system PCB.
UI module is connected to system module with a connector. System and rf
submodules are interconnected with PCB wiring. Unit can be connected to
accessories with a bottom system connector, which includes charging and
accessory control.
RF block is designed for a hand portable phone, which operates in NMT900
systems. Purpose of the RF module is to receive and demodulate radio frequency signal from the base station and to transmit a modulated RF signal
to the base station.
