RF Tuning Instructions

General

All tuning operations of the TME-1 are carried out using the WinTesla ser vice soft­ware.WinTesla interfaces with TME-1 via the FLA-26 service adapter.

For tuning the TME-1, use the same setup as for flashing the unit.

The tuning values of the phone are stored on the non-volatile memory of the RPM-3
GSM transceiver.. The contents of this memory can be read by the service software and
saved as a file. The program also enables writing the default tuning pa rameters, in which
case all tuning steps should be carried out.

During tuning, proceed as follows:

• Take care not to damage sensitive measuring instruments with exces sive RF
power. A spectrum analyzer may require an attenuator. TME-1 maximum out­put power may exceed 33 dBm (2 W) in GSM 900 band and 30 dBm (1 W) in
GSM1800 band.

• Carry out all tuning steps in the shortest possible time to avoid exces sive
heating of RF units.

• Perform all tuning steps in the order presented.

• Never try to mask a fault by tuning it out!

Required Equipment

• PC/AT computer with WinTesla service software; see separate section for
instructions on installation and use.

• Service accessories; see equipment setup lists.

• GSM radio telephone test station or separate measuring equipment as fol­lows:

- RF generator

- pulse power meter

- spectrum analyzer

- attenuator

Equipment Setup

Caution: Make sure that you have switched off the PC and the printer before mak­ing connections !

Issue 1 ãNokia Mobile Phones Ltd. Page 3

TME-1

Tuning and Flashing Instructions PAMS Technical Documentation

Caution: Do not connect the PKD-1 key to the serial port. You may damage your
PKD-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 PKD­1 between the PC and your printer cable.

Next see the following lists for correct equipment.

TME-1 SW Upgrade (flashing)

General

This quide gives instructions how to flash TME-1 and DTX-1.

DTX-1 and TME-1 has different kinds of memory circuits. Due to this the FPS-4 needs to
be configured before flashing. Both devices use different secondary boot code, and you
need to tell to FPS-4 manually which secondary boot code will be used.

NOTE! It is recommended that a second FPS-4 is configured and reserved for flashing of

the DTX-1.

Connections when flashing TME-1

• Connect the the DKT-6A between the FLA-7 and FLA-26.

• Connect the FLA-26 adapter on the TME-1 module.

• Connect the DTX-1 module on the FLA-26.

• Connect the PCS-1 power cable between the FLA-26 and FLA-7.

Be sure that the FPS-4 flash box is configured to flash the TME-1.

NOTE! When flashing the TME-1 module, the DTX-1 does not have to be connected!

Connections when flashing DTX-1

• Connect the DKT-6A cable from the FLA-7 to the connector labeled "TRUNK"
on the DTX-1.

• Connect the FLA-26 adapter on the TME-1 module.

• Connect the DTX-1 module on the FLA-26.

• Connect the PCS-1 power cable between the FLA-26 and FLA-7.

Be sure that the FPS-4 flash box is configured to flash the TME-1.

NOTE! When flashing the DTX-1 module, the TME-1 must be connected!

Before updating the modules it is recomended to save the customer specific settings
with the Nokia 22 Configurator software.

Installation program creates also three folders, RPM-3, DTX-1 and FPS-4 under WinTesla
folder.

Configuring FPS-4

Because of the DTX-1 and TME-1 has different kind of memory circuit, the FPS-4 need
to be configured before flashing. Both devices use different secondary boot code, and
you need to tell to FPS-4 manually which secondary boot code will be used.

The corresponding secondary boot code will be changed with the fps4.exe program.

Device Secondary boot code

TME-1 DCT3BT2.tia
DTX-1 DTX1SEC1.bin

• boot your PC to the DOS mode

• go to FPS4 directory

• if you want to flash DTX-1, write:

fps4 –Ls0DTX1SEC1.bin [ENTER]

• if you want to flash TME-1, write:

fps4 –Ls0DCT3BT2.tia [ENTER]

• restart your PC to Windows

• start WinTesla

• select the product to be flashed.

NOTE! It is recomended that a second FPS-4 is configured and reserved for flashing of
the DTX-1.

Getting started

If you want to flash the terminal, you need to select either TME-1 or DTX-1 (the one you
want to flash). In service use, both RPM-3 (TME-1) or DTX-1 can be selected, they both
contain same functions.

Flashing

First select the device that will be flashed: Product -> Open…
