For your safety

QUALIFIED SERVICE
Only qualified personnel may install or repair phone equipment.

ACCESSORIES AND BATTERIES
Use only approved accessories and batteries. Do not connect incompatible prod­ucts.

CONNECTING TO OTHER DEVICES
When connecting to any other device, read its user’s guide for detailed safety in­structions. Do not connect incompatible products.

ESD protection

Nokia requires that product service points have sufficient ESD protec­tion (against static electricity) when servicing products.

Any product of which the covers are removed must be handled with
ESD protection. The SIM card can be replaced without ESD protection
if the product is otherwise ready for use.

To replace the covers ESD protection must be applied.

All electronic parts of the product are susceptible to ESD. Resistors,
too, can be damaged by static electricity discharge.

All ESD sensitive parts must be packed in metallized protective bags
during shipping and handling outside any ESD Protected Area (EPA).

Every repair action involving opening the product or handling the
product components must be done under ESD protection.

ESD protected spare part packages MUST NOT be opened/closed out
of an ESD Protected Area.

For more information and local requirements about ESD protection
and ESD Protected Area, contact your local Nokia After Market Ser­vices representative.

Battery information

Note that a new battery's full performance is achieved only after two or three com­plete charge and discharge cycles!

The battery can be charged and discharged hundreds of times but it will eventually
wear out. When the operating time (talk-time and standby time) is noticeably
shorter than normal, it is time to buy a new battery.

Use only batteries approved by the phone manufacturer and recharge the battery
only with the chargers approved by the manufacturer. Unplug the charger when
not in use. Do not leave the battery connected to a charger for longer than a week,
since overcharging may shorten its lifetime. If left unused a fully charged battery
will discharge itself over time.

Temperature extremes can affect the ability of your battery to charge.

For good operation times with Ni-Cd/NiMh batteries, discharge the battery from
time to time by leaving the product switched on until it turns itself off (or by using
the battery discharge facility of any approved accessory available for the product).
Do not attempt to discharge the battery by any other means.

Use the battery only for its intended purpose.

Never use any charger or battery which is damaged.

Do not short-circuit the battery. Accidental short-circuiting can occur when a me­tallic object (coin, clip or pen) causes direct connection of the + and - terminals
of the battery (metal strips on the battery) for example when you carry a spare bat­tery in your pocket or purse. Short- circuiting the terminals may damage the bat­tery or the connecting object.

Leaving the battery in hot or cold places, such as in a closed car in summer or win­ter conditions, will reduce the capacity and lifetime of the battery. Always try to
keep the battery between 15°C and 25°C (59°F and 77°F). A phone with a hot or
cold battery may temporarily not work, even when the battery is fully charged. Bat­teries' performance is particularly limited in temperatures well below freezing.

Do not dispose of batteries in a fire!

Dispose of batteries according to local regulations (e.g. recycling). Do not dispose
as household waste.

Care and maintenance

The product is a product of superior design and craftsmanship and should be treat­ed with care. The suggestions below will help you to fulfil any warranty obligations
and to enjoy this product for many years.

Keep the phone and all its parts and accessories out of the reach of small children.

Keep the phone dry. Precipitation, humidity and all types of liquids or moisture can
contain minerals that will corrode electronic circuits.

Do not use or store the phone in dusty, dirty areas. Its moving parts can be dam­aged.

Do not store the phone in hot areas. High temperatures can shorten the life of
electronic devices, damage batteries, and warp or melt certain plastics.

Do not store the phone in cold areas. When it warms up (to its normal tempera­ture), moisture can form inside, which may damage electronic circuit boards.

Do not drop, knock or shake the phone. Rough handling can break internal circuit
boards.

Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the
phone.

Do not paint the phone. Paint can clog the moving parts and prevent proper oper­ation.

Use only the supplied or an approved replacement antenna. Unauthorised anten­nas, modifications or attachments could damage the phone and may violate regu­lations governing radio devices.

All of the above suggestions apply equally to the product, battery, charger or any
accessory.

Phoenix User’s Guide

Introduction

This section briefly describes how to install the Phoenix software and includes some
basic information on how to use the program. For more detailed information, please refer
to the Phoenix Help files. Each feature in Phoenix has its own Help function, which can
be activated while running the program.

Setting up Phoenix

1 Download the latest release. Please contact your regional Customer Care Solu-

tions contact for information on where to download the latest release.

2 Install Phoenix by executing the Phoenix installation package and follow the

instructions on the screen.

Note: In some products, the setup may require you to reboot the computer. In either case, the setup
will register Phoenix components. This process can take several minutes.

3 Download the latest data packages for the products you will be using.

By default, the program files are stored under C:\Program Files\Nokia\Phoenix

The Phoenix program has been built using component architecture. This means that the
actual program is very small and most of the program’s functionality is divided into
dynamically loaded modules (DLLs).

The data packages will create product-specific directories under the installation direc­tory.

Installing Phoenix

1 Before you start installing the program, check that:

• the dongle is attached to parallel port. Contact your supervisor in order to obtain
a suitable dongle.

• you have administrator rights (Windows NT or Windows 2000). This is required in
order to be able to install Phoenix.

2 The installation checks that the latest supported dongle driver version is

installed. The dongle driver is installed if there is no previous installation of the
dongle driver or if the installed dongle driver is older than the latest supported
version.

3 Reboot your PC before using Phoenix, if you are requested to do so.

Uninstalling Phoenix

Uninstalling another Phoenix version:

Page 6  2004 Nokia Corporation. Issue 2 07/2004

Company Confidential RH-21

Nokia Customer Care Service Software Instructions

1 Make sure that the dongle is attached.

2 Go to Control Panel and select Add/Remove Programs.

3 Select TSS4 Phoenix Release xx.yy.zzz for uninstallation and click Add/Remove.

4 Click OK to remove the application.

You may be required to reboot your PC after uninstallation.

Note: If you have different product packages installed, the components are uninstalled only if they are
not included in other product packages.

Data Packages

Data Packages (DP) is a name for a helpful feature in the Phoenix software. This feature
provides a flexible way of distributing and installing Phoenix and its data files.

All product-specific data is separated from the program code and installed separately.
This means that the installation is performed in at least two steps.

Each product has its own DP. The FPS-8 flashing equipment also has its own package.

Starting a session

Concepts

In the Phoenix context, Product means the cellular phone attached to a PC. More specif­ically, it is a particular type of phone.

Connection means the type of cable used to attach the phone to the port to which the
other end of the cable is attached.

Selecting a connection

The connection defines the cable and the communications port that will be used when
connecting to the phone.

1 Active connections are listed in the toolbar’s Connection drop-down menu. You

should make sure that the connection is correct before using the software.
Change it, if necessary.

In case the connection is the wrong one, you need to create a new one.

2 Select Settings from the drop-down menu.

3 Select Add in the Connection List Dialog and fill in the relevant fields in the Con-

nection setup dialog.

Selecting a product

Many of Phoenix’s features are product-specific. It is, therefore, mandatory to choose the

Issue 2 07/2004  2004 Nokia Corporation. Page 7

RH-21 Company Confidential
Service Software Instructions Nokia Customer Care

product you will be working on at the beginning of the session.

1 Select File - Scan Product (or hold the Ctrl key down and press R). Phoenix will

scan the connected product and load additional menus which are designed for
the product. If the product is not supported, then an error message will be dis­played and a different Phoenix data package may be required.

2 If you want to manually choose the product or if the phone is dead, select File -

Choose Product. You will be presented with a list of available products.

After the product selection, you will see an additional menu item on the main menu. If
you take a look at the available menu items, you will see that their number has
increased.

Phoenix environment

You can configure the program’s main toolbar and the product or tool-specific options to
your liking.

You can control which toolbars are visible by selecting View and Toolbars from the drop-
down menu. The visible toolbars are marked with a check.

The rest of the options are product- or tool-specific. The tool-specific options are set
using the associated toolbar.

Using components

When working with Phoenix, each task generally has its own component that will per­form the task. The first thing, therefore, is to open the desired component.

Opening a component means that you open a tool window within Phoenix.

Nokia Customer Care Troubleshooting

Troubleshooting

The first thing to do when a problem is encountered is to carry out a thorough visual
check of the module. Make sure that:

• there are no mechanical damages

• the solder joints are OK

Note: Before changing anything, ALL SUPPLY VOLTAGES AND THE SYSTEM CLOCK / SLEEP
CLOCK should be checked.

Baseband Troubleshooting

General testing information

There are three different modes for testing and/or repairing the phone. The mode can be
selected with suitable resistors connected to BSI- and BTEMP- lines as illustrated in the
following table:

Table 1: Phone operating mode

Mode BSI- resistor

Nor-

68k 75k

BTEMP
resistor

Remarks

mal

Local 560_(<1k_) Whatever

Test > 1k 560_(<1k_) Recommended for baseband testing. Same as

local mode, but making a phone call is possi­ble.

If the corresponding resistors are connected, the MCU software automatically enters into
the local or test mode when the supply voltage is connected to the phone.

The power can be switched on by:

1 Pressing the power key.

2 Connecting the local/test mode resistors to the BSI/BTEMP lines and connecting

the battery voltage to the phone.

3 Connecting a charger.

4 Using the phone’s internal functions (real-time clock alarm).

In the local and test mode, the baseband can be controlled through MBUS or FBUS (FBUS
is recommended) connections using Phoenix service software.

Troubleshooting

Note: Most of the baseband repair actions require removing the baseband shield. The shield must not
be removed unless separately authorized by the program.

Note: The phone’s ESN has to re-written to the UEM, if the UEM is replaced. This can be done only in
Central Service.

1 The UEM acts as a HW master during start up

• Vbatt limits: 2.1V for internal state machine, 3V triggering whole startup

• Regulator sequencing

• HW "core" regulators "on": Vio, Vcore, VR3, Vflash1

• These regulators supply the processors, memory chip interfaces and clock source
in RF

• Reset releasing delay

Page 6  2004 Nokia Corporation. Issue 2 07/2004

Nokia Customer Care Troubleshooting

• Supply voltages stabilize to their UEM HW default values

• RFCLK grows to full swing

• The core is ready to run but waiting for the PURX release

• Reset releasing

• The UPP releases the SLEEPX up to the "non sleep" state to prevent the UEM
switching the regulators "OFF"

2 MCU starts running the Bootstrap Code

• written in stone/ UPP internal ROM

• the program checks if there is any reason for the FDL mode (Flash Down Load)

• If there is an executable code in FLASH and there is no reason for FDL, the MCU
starts running the MCU program from FLASH

3 MCU runs the FLASH MCU code

• the phone initialization, user interfaces, internal blocks, etc.

• Core regulator voltage setting for required DSP speed

• Initializes the DSP and concerning HW

• Releases DSP reset -> DSP starts running

Note: In the following figure, the RF_Clk frequency appears to be lower than 19.44MHz because of a
too low oscilloscope sampling frequency (2kS/s).

Phone does not start up normally or does not stay on

Note: In the case of power-up faults, it is not possible to force the phone on by disabling the watchdog.
Instead, measurements should be taken immediately when the power key is pressed or when the bat­tery voltage is connected to the phone (local / test mode).

The easiest way to check if the software is running when the phone takes an abnormal
amount of current is to measure the cbusclk and Vcore.

The Dbus clock (programmable 9.72MHz) is not automatically visible in the test and local
modes.

Flash Programming does not work

Flash programming procedure

1 The phone communicates with the prommer via the production test pattern,

using the following signals:

• FBUSTX (serial data to phone)

• FBUSRX (serial data from phone)

• MBUS (serial clock for FBUSRX)

• VPP (External flashing voltage for speed up flashing)

• The BSI line is also used when initializing flashing (battery connec- tor)

2 When the phone is powered (VBAT>3V), the MBUS and FBUSTX lines are pulled

up internally by the phone.

3 The prommer sends a command to the UEM, using FBUSRX, to enter the Flash-

mode. During the sending of this command, the prommer keeps the BSI line high
and MBUS is used as a serial clock.

4 When the Flash-mode command is acknowledged, UEM enters the Flash-mode

and releases reset (PURX) to MCU.

5 After reset is released, UPP checks if there is a request for the Bootstrap code

(that resides in the UPP ROM).

6 The request for Bootstrap is the MBUS pulled down by the prommer (if the boot-

strap is not requested, the bootstrap code jumps to FLASH SW).

7 If the Bootstrap code is requested, UPP enters the Flash-mode and sets FbusTX to

'0' as an acknowledgement to the prommer. This is an indication that UPP can
run, at least, the fixed Bootstrap code – although it is not able to run the FLASH
code. UPP then sends an UPP-ID to the prommer via the FBUSTX line.

8 After the prommer has received the UPP-ID, it sends a corresponding Secondary

Boot Code to the phone via FBUSRX. The Secondary Boot Code, when run in UPP,
requests UPP to send information to the prommer about the flash type and other
HW-related parameters about the device to be flashed.

9 The prommer then sends the Algorithm Code corresponding to the HW parame-

ters, and this algorithm, when run in UPP, takes over handling the MCUSW trans­fer to Flash.

10 12 volts can be supplied to Vpp (by the prommer) to speed up flashing.

11 The FLASH Program includes a package of MCU and DSP software and all default

parameters for the phone. The tuning values will be added/rewritten during the

Charging

Note: The charging voltage and current can be checked by connecting the phone to the service soft­ware and reading the ad- converter values of the vchar and ichar.

If charging fails when the ACP-9 or the LCH-9 is used, but works with ACP-7, ACP-8, and
LCH-8, check that the charge control pin of the system connector is connected to the
ground.

Audio failures

In case of audio failures, there are three possibilities to check the audio lines.

1 Make a phone call against tester and check audios.

2 If the earpiece/XMIC fails: Feed a 1Khz signal to the XMIC line and measure the

signal from the earpiece line. The Audio test box JBA-8 is needed. The Audio loop
(Audio test/Ext In Hp Out) must be switched on by the Phoenix service software.
This loop will connect audios only through the UEM. In this case, the UPP is not
used.

If the internal microphone/XEAR fails: Feed the tone to the microphone and measure the
signal from the XEAR line. The Audio test box JBA-8 is needed. The Audio loop (Audio
test/Hp In Ext Out) must be switched on by the Phoenix service software. This loop will
connect audios only through the UEM. In this case, the UPP is not used.

3 Run the audio-loop self-test with Phoenix (BB Self Tests/

ST_EAR_DATA_LOOP_TEST). This loop will test the ear-data/mic-data lines

between the UPP and the UEM.

Accessory detection

1 Start the phone in the normal mode when checking for accessory detection.

2 The Ad-converter value of the hookint-line can be checked with the Xmic switch

on an MJ-8 test jig. Changes normally from high to low when no accessory is
connected.

3 When the headset HDC-5 is connected, the hookint-value should be between

600 and 800.

• No sound: Try using a known good SALT speaker instead. If there is still no sound,
change the UEM (D200)

• Weak sound: Use the Audio test in Phoenix to set the SALT speaker parameters
(frequency, strength). If it does not affect the sound level, change the SALT
speaker.

Vibra does not work

Check spring connectors and C307 and C308.

• No vibration: Try using a known good vibra instead. If there is still no vibration,
change the UEM (D200)

• Weak vibration: Use the Vibra test in Phoenix to set the vibra’s parameters (fre­quency, duty cycle). If it does not affect the magnitude of the vibration, change
the vibra.

Keyboard does not work

Check that there is no dirt between the dome sheet and the PWB. If the keyboard still
does not operate normally, try to use the Keyboard test in Phoenix to see if the pressed
key is identified. If it is not identified, change the UPP (D400).

Receiver Troubleshooting

General Instructions for RX troubleshooting

Start the Phoenix software and use it to start the required RX mode of the mobile phone.
The troubleshooting flowchart is divided into three steps: (1) general checking, (2) local
checking, and (3) RX-chain checking. Always use an RF cable connected from an external
RF connector to the analyzer via (RF power) attenuator. This is important to protect the
analyzer against excessive RF power and to prevent leakage of undesired RF power into
the cellular frequencies.

1 Start the Phoenix software and select the TX mode under Testing (AMPS, DAMPS,

or TDMA1900).

2 It is useful to select the mid channel (383 for AMPS/DAMPS or 1000 for

TDMA1900) and the power level 2.

Note: Before changing ASICs or filters, all solderings and missing components must be checked visu­ally. After any possible component changes, the phone must be tuned with the Phoenix autotune SW.
