Service Software Instructions for NHA–2 and NHA–4
Introduction
General
The Service Software is specially designed to facilitate the servicing of fifth
generation cellular telephones.
The software can be used to control the phone according to the user’s requirements merely by entering commands via the keyboard / mouse of a PC connected to the phone.
This section refers to AMPS Service Software Version 1.00. NMP After Sales
will notify service personnel about future upgrades via Technical Bulletins. Software upgrades will be available from your local NMP outlet.
Required Servicing Equipment
– Computer: IBM PC / AT or compatible with one unused serial port (COM1 or
COM2*), one parallel port (LPT1), hard disk recommended.
– Operating System: DOS Version 3.3 or later
– 500 kB free memory under DOS
– Display: Any 80–character text display
– PC Locals program: LSA–3K (product code 0193697) for 3.5” disk or
LSA–3L (product code 0193698) for 5.25” disk.

*)
Note: A number of PC’s of an older generation use the Intel, National Semiconductor, or
Original, 33/96
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.

Service Software Instructions for NHA–2 and NHA–4
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 (DAU–4S and XCM–1).
Attach the protection key PKD–1 to parallel port one (25–pin female D–connector) of the PC. When connecting the PKD–1 to the parallel port be sure that you
insert the PC end of the PKD–1 to the PC (male side). If you use a printer on
parallel port one, place the PKD–1 between the PC and your printer cable.
The PKD–1 should not effect 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.

Using Menus
There are three visible components to service software: the menu bar at the
top, the window area in the middle, and the status line at the bottom of the
screen. Many menu items also offer dialog boxes. Although there are several
different ways to make a selection in service software, they access the same
commands and dialog boxes.
Menu Bar
The menu bar is the primary access to all the menu commands.
Here is how you choose menu commands using the keyboard:
Service Software Instructions for NHA–2 and NHA–4
– Press
the items on the menu bar.
– Use the ← → arrow keys to select the menu you wish to display and then
press
ter of the menu title. For example, when the menu bar is active, press F to
move to and display the File menu. At any time press
letter (e.g.
– Use the ↑
and press
menu command.
At this point service software either carries out the command, displays a dialog
box, or displays another menu.
There are two ways to choose commands with a mouse:
– Click the desired menu title to display the menu and click the desired com-
mand.
– Drag straight from the menu title down to the menu command. Release the
mouse button on the command you want. If you change your mind, just
drag off the menu; no command will be chosen.
Service software offers a number of quick ways to choose menu commands.
The click–drag method for mouse users is an example. From the keyboard, you
can use a number of keyboard shortcuts (or ’hotkeys’) to access the menu bar,
choose commands or work with dialog boxes. You need to hold down
pressing the highlighted letter when moving from input box to a group of buttons or boxes.

Windows
Some of the actions you see and do in Service Software happens in a window.
A window is a screen area that you can open, close, and move.
Most of the windows have these things in common:
– a title bar
– a close box
The following figure shows a typical window:

Dialog Boxes
Most of the menu commands lead to a dialog box. Dialog boxes offer a convenient way to view and set multiple options. They are typically used for making
settings or performing some action where the phone must be in a certain state
and all other actions must be denied. When you are making settings in a dialog
box, you work with five basic types of on–screen control:
– action buttons
– radio buttons
– check boxes
– input boxes
– list boxes
Dialog boxes also have similar features to windows; title bar and close box. Below is a sample box which lists some of these features:
