Technical Documentation
Introduction
General
This service software is prepared for the NHN–2N and NHN–3N phones.
The software can be used to control the phone according to the user’s wish
merely by entering commands via the keyboard of a PC/AT connected to the
phone. It is equally usable for the simple expedient of programming user identification data as for a full–scale tuning of the phone.
This section references NMT service software version 1.5. To receive a free upgrade, send the disk back to Nokia Mobile Phones.
Software Structure
The software is divided into five main menus: File, service, dealer, options and
help.
Declarations about these menus can be accessed by pressing ALT – F1 when
menu item is highlighted. If any menu item is not highlighted ALT – F1 gives
general information about the program. Help is also available when a dialog
box is opened.

Note: A number of PC’s of an older generation use the Intel, National Semiconductor, or
United Microelectronics IC 8250 as the serial port UART. This is a comparatively
inefficient circuit for current purposes and does not necessarily support the
M2BUS adapter at 9600 baud. The newer UART’s NS16450 and NS16550AF of
National Semiconductor offer solutions for these problems.

Installation
Mechanical Connections
Caution: Ensure that you have switched off the PC and the printer before
making connections !
Caution: Do not connect the PKD–1 to the serial port. This could damage
the PKD–1 !
The software controls the phone via a separate adapter connected to the serial
port of the PC and to the telephone’s M2BUS (SCN–3).
Attach the dongle PKD–1 to the parallel port 1 (25–pin female D–connector) of
the PC. When connecting PKD–1 to the parallel port be sure that you insert
computer side of the PKD–1 to the PC (male side). If you use a printer on parallel port 1 place the PKD–1 between the PC and your printer cable.
The PKD–1 should not affect devices working with it. If some errors occur (errors in printing are possible) please try printing without the PKD–1. If printing is
OK without the PKD–1 please contact your dealer. We will offer you a new
PKD–1 in exchange for your old one.

Installing the Software on PC Hard Disk
The program is delivered on a diskette and is copy protected with a dongle
PKD–1. It must be present in parallel port when using Pclocals software.
The program can also be installed on the hard disk, which is recommendable to
obtain a maximum data access rate.
Don’t lose your original diskette to enable upgrading the program !
If you are plan to use PCL Start service software, you must install it before
installing Pclocals, see PCL Start installation instructions.
To install the new Pclocals program, follow steps below:
1. insert the new Pclocals diskette
into drive A: of your computer
2. log into drive A:
3. start INSTALL.BAT and
install Pclocals to drive C:

File Menu
1 Open
Gives you choice to open any default channel file.
2 Save
Saves the previously edited channel defaults as ”default.set”. If file ”default.set”
is not defined, the program uses default channels.
3 Save as
Same as previous, but the file name can be specified.
4 Edit
This is a dialog box where you can set default channels. Channel values are
used while tuning and testing. In addition separate RSSI values are used in
RSSI and AGC tunings. If you are satisfied with ordinary channels that depend
on the phone country version, you do not have to set default channels. See
section 6–3 Tuning instructions to check where the default channels are used.
NHN–3N
5 Change dir
Changes the default directory.
6 Dos shell
You can leave the program temporarily to perform a DOS command or run
another program. Type exit to return.
7 Exit
This command terminates the program.

Battery Save/Sleep Mode Allowed
Note: These are only modified from MCU functions keys:
The Battery Save Allowed option enables activation of the NMT network bat-
tery preserving function. When activated, it sets the phone into a low–consumption mode for a period determined by the NMT exchange.
The Sleep Mode Allowed option enables activation of the NMT network sleep
mode function. When activated, the phone uses slower channel scanning when
it is in an area where the field strength is bad.
Own Number
The Own Number is the number shown in short code memory location 11. You
can change contents of the short code memory location 11 directly from the
phone user interface too. Area code and subscriber number are entered here.
Own number length is 6 digits.
Lock Code
The phone’s lock code is programmed here.
NHN–3N
Basic Band 1 First
This number defines the first channel searched for the call. In the Nordic countries the value 1 applies.
Basic Band 1 Last
This number defines the last channel from which the calling channel is
searched. The value for the Nordic countries is 304.
2 Short–code Memory
A total of 10 short–code memory locations can be used on the phone. The contents of a memory location can be edited and copied from a phone to another
using the Pclocals software. In addition to reading from the phone and writing
into it, the program allows saving the contents of the short–code memory as
files. Reading of GSM and NMT450.scm files is supported. The short code
memory can also be cleared here.
Number field length is 24 digits.

mode is normal when using the phone in the NMT network. The local mode is
needed to place the phone in the desired mode for maintenance. It is also used
at the production stage. Phone subscriber data writing demands local mode
too. Local mode is always initialized when tuning or testing is selected.
