• IF THE DEVICE CAN BE INSTALLED IN A VEHICLE, CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED
WITH ELECTRONIC ENGINE MANAGEMENT SYSTEMS AND ANTI-SKID BRAKING SYSTEMS. UNDER CERTAIN FAULT
CONDITIONS, EMITTED RF ENERGY CAN AFFECT THEIR OPERATION. IF NECESSARY, CONSULT THE VEHICLE DEALER/
MANUFACTURER TO DETERMINE THE IMMUNITY OF VEHICLE ELECTRONIC SYSTEMS TO RF ENERGY.
• THE PRODUCT MUST NOT BE OPERATED IN AREAS LIKELY TO CONTAIN POTENTIALLY EXPLOSIVE ATMOSPHERES,
FOR EXAMPLE, PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC.
• OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLULAR TELEPHONES, MAY INTERFERE
WITH THE FUNCTIONALITY OF INADEQUATELY PROTECTED MEDICAL DEVICES. CONSULT A PHYSICIAN OR THE
MANUFACTURER OF THE MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS. OTHER ELECTRONIC EQUIPMENT MAY
ALSO BE SUBJECT TO INTERFERENCE.
• BEFORE MAKING ANY TEST CONNECTIONS, MAKE SURE YOU HAVE SWITCHED OFF ALL EQUIPMENT.

Cautions
• Servicing and alignment must be undertaken by qualified personnel only.
• Ensure all work is carried out at an anti-static workstation and that an anti-static wrist strap is worn.
• Ensure solder, wire, or foreign matter does not enter the telephone as damage may result.
• Use only approved components as specified in the parts list.
• Ensure all components, modules, screws and insulators are correctly re-fitted after servicing and
alignment.
• Ensure all cables and wires are repositioned correctly.
• Never test a mobile phone WCDMA transmitter with full Tx power, if there is no possibility to perform the
measurements in a good performance RF-shielded room. Even low power WCDMA transmitters may disturb
nearby WCDMA networks and cause problems to 3G cellular phone communication in a wide area.
• During testing never activate the GSM or WCDMA transmitter without a proper antenna load, otherwise
GSM or WCDMA PA may be damaged.

Care and maintenance

Care and maintenance
This product is 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.

ESD protection

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

Battery information
Note: 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 Li-Ion 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.

Backlight LED components are inside the display
module. Backlight failure can also be in the
connector or in the backlight power source in the
main engine of the phone.
This means that in case the display is working
(image OK), the backlight is faulty.

Visual defects (pixel)

Pixel defects can be checked by controlling the
display with Phoenix. Use both colours, black and
white, on a full screen.
The display may have some random pixel defects
that are acceptable for this type of display. The
criteria when pixel defects are regarded as a display
failure, resulting in a replacement of the display, are
presented the following table.

Two single dot defects that are within 5 mm of each other should be
interpreted as combined dot defect.

Steps
1. Verify with a working display that the fault is not on the display module itself.
The display module cannot be repaired.
2. Check that the cellular engine is working normally.
i

To check the functionality, connect the phone to a docking station.

StartPhoenix service software.

iii Read the phone information to check that also the application engine is functioning normally (you
should be able to read the APE ID).
3. Proceed to the display fault troubleshooting flowchart.
Use the Display Test tool in Phoenix to find the detailed fault mode.

ALS functionality check

Steps
1. Connect phone to Phoenix and set the phone (e.g. on the table) so that the amount of ambient light seen
by ALS is as stable as possible.
2. Start Phoenix
3. Choose File -> Scan product
4. Choose Testing -> Display Test
5. Open the Lights tab, check Ambient Light Sensor check box, click Read, cover the sensor and click Read
again. When covered, Luminance reading should be less than after clicking Read without covering the
sensor.
6. If component doesn’t give any reading or reading doesn’t change when sensor is/is not covered, replace
the part.

Note: After replacing the ALS. If calibration values of the new sensor are lost or for some other
reason, ALS re-tuning is required (see instructions later in this document).
When doing the ALS calibration procedure, it is required to have a reference phone, which includes
calibrated ALS. ALS re-tuning instructions show why the reference phone is needed.

ALS retuning

Steps
1.

Connect reference phone to Phoenix and set the phone (e.g. on the table) so that the amount of ambient
light seen by ALS is as stabile as possible.

Start Phoenix.

Choose File→Scan Product.

4.

Choose Tuning -> Ambient Light Sensor Calibration. You should see the following window

Read AD-count values for Channel 0 and Channel 1 by click Read button and write them down.

Repeat 1-5 for the phone to be calibrated and make sure the phone to be calibrated is located in the
same place as reference phone was when luminance reading was taken.

Calculate co-efficient from reference phone and phone to be calibrated AD-count values by division: Coefficient = AD-count(reference phone) / AD-count(phone to be calibrated), write down the calculated coefficient values.

-> Iterate by changing Channel 0 and Channel 1 (reference level) values (remove cross from ‘Use default
values only’). After writing some value to Channel 0 and Channel 1 (reference value), calibrate button
must be pressed. Stop iterating when Co-efficient is equal to Co-efficient calculated in bullet 7. Note that
decimal numbers should be used in the iteration in order to achieve enough precision (e.g. 200.2455)

After having same Co-efficient value in “Co-efficient” textbox as the calculated value, make sure that
ambient light values (read using Testing → Display Test → “Luminance” textbox) are almost the same
in reference phone and calibrated phone. Remember that illuminance readings for reference and
calibrated phones must be done in the same ambient light conditions. If illuminance values differs a lot
(difference max. +- 10%), repeat whole ALS re-tuning procedure.

10. To end the calibration, click Close.

Camera module troubleshooting
Introduction to camera troubleshooting
Bad conditions often cause bad pictures. Therefore, the camera operation has to be checked in constant
conditions or by using a second, known-to-be-good Nokia device as reference. Image quality is hard to
measure quantitatively, and the difference between a good and a bad picture can be small. Some training
or experience may be needed to detect what is actually wrong.
When checking for possible errors in camera functionality, knowing what error is suspected significantly
helps the testing by narrowing down the amount of test cases. The following types of image quality problems
are common:
• Dust (black spots)
• Lack of sharpness
• Bit errors

Camera troubleshooting

Taking and evaluating test pictures
When taking a test picture, remember the following:
• Avoid bright fluorescent light, 50/60Hz electrical network or high artificial illumination levels
• If the phone is hot, let it rest for a while before taking the picture
• Make sure the optical system is clean
• Use highest possible resolution
• Make sure the light is sufficient (bright office lightning)
• Do not take the picture towards a light source
• Hold the phone as still as possible when taking the picture
• If camera has auto focus: Pictures should be taken both at infinity ~>2m and at macro distance ~10-15 cm
in order to verify auto focus functionality
When evaluating a test picture, remember the following:
• The center of the picture is sharper than the edges
• The image may be blurred, though it does not show in the viewfinder
• Analyse the picture from your PC monitor, full colour setting is recommended
• If possible, compare with a picture of the same motive taken with a similar Nokia device
• If camera has auto focus: Remember that the white focussing frame which appears when the camera
button is pressed halfway down, must turn green for auto focus lock. If the frame turns red, the camera
is not focussed!

Audio troubleshooting
Audio troubleshooting test instructions
Differential external earpiece and internal earpiece outputs can be measured either with a single-ended or
a differential probe.
When measuring with a single-ended probe each output is measured against the ground.
Internal handsfree output is measured using a current probe, if a special low-pass filter designed for
measuring a digital amplifier is not available. Note also that when using a current probe, the input signal
frequency must be set to 2kHz.
The input signal for each loop test can be either single-ended or differential.

Required equipment
The following equipment is needed for the tests:
• Oscilloscope
• Function generator (sine waveform)
• Phoenix service software
• Battery voltage 3.7V

Test procedure
Audio can be tested using the Phoenix audio routings option. These different audio loop paths can be
activated:
• Mic2P to Internal earpiece
• Mic2P microphone to Internal handsfree speaker
Each audio loop sets routing from the specified input to the specified output enabling a quick in-out test.
Loop path gains are fixed and they cannot be changed using Phoenix. Correct pins and signals for each test
are presented in a table in the following section.

Phoenix audio loop tests and test results
The results presented in this table apply when no accessory is connected and battery voltage is set to 3.7V.
Earpiece, internal microphone and speaker are in place during measurement. Applying a headset accessory
during measurement causes a significant drop in measured quantities.
The gain values presented in the table apply for a differential output vs. single-ended/differential input.

Acoustics troubleshooting

Introduction to acoustics troubleshooting
Acoustics design ensures that the sound is detected correctly with a microphone and properly radiated to
the outside of the device by the speaker. The acoustics of the phone include three basic systems: earpiece,
integrated handsfree (IHF) and dual microphone (for noise cancelling).
The sound reproduced from the earpiece eradiates through a single hole on the front cover (A-cover). The
sound reproduced from the IHF speaker radiates from the sound hole located on the back side on the top
part of the phone. The inlets for the 2 microphones are found in the bottom and next to the capture key,
respectively.

BB Troubleshooting and Manual Tuning Guide
For a correct functionality of the phone, all sound holes must be always open. When the phone is used, care
must be taken not to close any of those holes with a hand or fingers. The phone should be dry and clean,
and no objects must be located in such a way that they close any of the holes.

RF troubleshooting

General RF troubleshooting
Introduction to RF troubleshooting

Most RF semiconductors are static discharge sensitive
ESD protection must be applied during repair (ground straps and ESD soldering irons).

Pre-baking
These parts are moisture sensitive and must be pre-baked prior to soldering:
• VAPAUS RFIC (N7500)
• TX FEM (N7520)
• WCDMA PA (N7540)
• Aura DC/DC converter (N7560)

Discrete components
In addition to the key components, there are a number of discrete components (resistors, inductors and
capacitors) for which troubleshooting is done mainly by visual inspection.
Capacitors: check for short circuits.
Resistors: check value with an ohm meter.
Note: In-circuit measurements should be evaluated carefully.

Measuring equipment
All measurements should be done using:
• Module jig MJ-204
• Flash adapter FS-98
• Control unit CU-4/Interface adapter SS-46
• An oscilloscope for low frequency and DC measurements. Recommended probe: 10:1, 10MOhm/8pF.
• A radio communication tester including RF generator and spectrum analyser, for example Rohde & Schwarz
CMU200. (Alternatively a spectrum analyser and a RF generator can be used. However, some tests in this
guide are not possible to perform if this solution is chosen).
Note: A mobile phone WCDMA transmitter should never be tested with full TX power (only if it is
possible to perform the measurement in a good RF-shielded room). Even low power WCDMA
transmitters may disturb nearby WCDMA networks and cause problems to 3G cellular phone
communication in a wide area.
Note: All measurements with an RF coupler should be performed in an RF-shielded environment
because nearby base stations can disturb sensitive receiver measurements. If there is no possibility
to use RF shielded environment, testing at frequencies of nearby base stations should be avoided.

Level of repair
The scope of this guideline is to verify functionality of the cellular RF block without removing RF shield.
Instructions for finding the faulty component are provided in some cases, but the whole RF block still needs
to be replaced even when a single component is faulty.

Auto tuning
Introduction to auto tuning
This phone can be tuned automatically.
Auto tune is designed to align the phone's RF part easier and faster. It performs calibrations, tunings and
measurements of RX and TX. The results are displayed and logged in a result file, if initiated.

Receiver troubleshooting
Introduction to receiver (RX) troubleshooting
RX can be tested by making a phone call or in local mode. For the local mode testing, use Phoenix service
software.
The main RX troubleshooting measurement is RSSI reading. This test measures the signal strength of the
received signal. For GSM RSSI measurements, see section GSM RX chain activation for manual measurements/
GSM RSSI measurement (page 4–9) . For a similar test in WCDMA mode, see section WCDMA RSSI
measurement (page 4–12).
The RX path for GSM and WCDMA are using the same filters in some bands. Please refer to RM-470 RF
components reference (page 4–26) for details.

Transmitter troubleshooting
Introduction to transmitter (TX) troubleshooting
Please note the following before performing transmitter tests:
• TX troubleshooting requires TX operation.
• Do not transmit on frequencies that are in use!
• The transmitter can be controlled in local mode for diagnostic purposes.
• The most useful Phoenix tool for GSM transmitter testing is “RF Control”; in WCDMA transmitter testing
the best tool is “TX Control”.
• Remember that re-tuning is not a fix! Phones are tuned correctly in production.
• The RX path for GSM and WCDMA are using the same filters in some bands. Please refer to RM-470 RF
components reference (page 4–26) for details.
Note: Never activate the GSM or WCDMA transmitter without a proper antenna load. Always connect
a 50Ω load to the RF connector (antenna, RF-measurement equipment or at least a 2W dummy load);
otherwise the GSM or WCDMA Power amplifier (PA) may be damaged.

Antenna
Antenna overview
The phone has one antenna module. The antenna module is covering GSM and WCDMA bands along with GPS
and BT. The antenna module consists of a antenna carrier and an LDS antenna, where the antenna pattern
is directly deposited on the antenna carrier.
The antenna module also acts as IHF chamber, and contains a speaker and an earpiece. The main antenna
has one feed pad for GSM and WCDMA, one feed pad for GPS, one feed pad for BT, one antenna switch pad
and two ground pads. All six pads connect to C-springs mounted on the AV-flex.

Main antenna functionality
The antenna module is functioning normally when all six contact pads take proper contact to the C-springs
on the AV-flex, and the and the antenna pattern is electrically intact.
The main antenna functionality must also be checked by measuring the transmitted power with RF coupler
at GSM900 channel 124.

Antenna troubleshooting

Antenna contacts, visual check
The antenna module has one feed pad for GSM and WCDMA, one feed pad for GPS, one feed pad for BT, one
antenna switch pad and two ground pads. Check that all pads take proper contact to the C-clips on the AVflex.

Antenna matching components and antenna switch related components, visual
check
There is one filtering component on GSM/WCDMA feed, two matching components on GPS feed and two
matching components on BT feed. There are also 20 antenna switch related components located at the
antenna switch connection and next to the antenna switch.
All matching and antenna switch related components are soldered on the AV-flex. Check visually that all
components are properly soldered on the AV-flex. In the case of damage you need to replace the AV-flex.

Energy management
Battery and charging

BL-6Q battery
The phone is powered by a 3-pole BL-6Q 960 mAh battery (Li-Ion). The three poles of the battery are named
VBAT, BSI and GND, where the BSI line is used to recognize the battery capacity. This is done by means of an
internal battery pull down resistor.

Figure 34 Battery pin order

The battery temperature is estimated by measuring separate battery temperature NTC via the BTEMP line of
EM ASIC (N2200). This resistor is located on the main PWB, at a place where the phone temperature is closest
to the battery temperature.

Battery connector
The battery connector is a blade connector. It has three blades;
• BSI (Battery size indicator)
• GND (Ground)
• VBAT (Battery voltage)
The BSI line is used to recognize the battery capacity by a battery internal pull down resistor.

Figure 35 Blade battery connector

Charging
This phone is charged through the smaller Nokia standard interface (2.0 mm plug). The wider standard
charger plug (3.5 mm) can be used together with a CA-44 charger adapter.

Issue 1

Page 5 –9

RM-470
System Module

Figure 36 Small (right) and wide (left) charger plugs

The phone can also be charged via USB using CA-101.
Charging is controlled by EM ASIC (N2200), and external components are needed to protect the baseband
module against EMC, reverse polarity and transient frequency deviation.

Charging a dead battery
Charging of a dead battery has to be carried out via an approved NOKIA charger. If the phone is charged via
USB, CA-101 must be used.

Normal and extreme voltages
Energy management is mainly carried out in the EM ASIC (N2200). that contains a number of regulators. In
addition there are also some external regulators.
In the table below normal and extreme voltages are shown when a BL-6Q battery is used.

Power key and system power-up
When the battery is placed in the phone, the power key circuits are energized. When the power key is pressed,
the system boots up (if an adequate battery voltage is present).
Power down can be initiated by pressing the power key again and the system is powered down with the aid
of SW. The power key is connected to EM ASIC (N2200) via the PWRONX signal.

Modes of operation
Mode

Description

NO_SUPPLY

(Dead) mode means that the main battery is not present or its voltage is too low (below
EM ASIC master reset threshold) and that the back-up battery voltage is too low.

BACK_UP

The main battery is not present or its voltage is too low but back-up battery voltage is
adequate and the 32 kHz oscillator is running (RTC is on).

PWR_OFF

In this mode (warm), the main battery is present and its voltage is over EM ASIC master
reset threshold. All regulators are disabled, PurX is on low state, the RTC is on and the
oscillator is on. PWR_OFF (cold) mode is almost the same as PWR_OFF (warm), but the
RTC and the oscillator are off.

RESET

RESET mode is a synonym for start-up sequence. RESET mode uses 32kHz clock to count
the REST mode delay (typically 16ms).

SLEEP

SLEEP mode is entered only from PWR_ON mode with the aid of SW when the system’s
activity is low.

FLASHING

FLASHING mode is for SW downloading.

Clocking scheme
In BB5.44, two main clocks are provided to the system: 38.4MHz RF clock produced by VCTCXO in the RF section
and 32.768kHz sleep clock produced by EM ASIC N2200 with an external crystal.
32 k Sleep Clock is always powered on after startup. Sleep clock is used by RAPU for low-power operation.
SMPS Clk is 2.4MHz clock line from RAPU to EM ASIC N2200. In deep sleep mode, when VCTCXO is off, this signal
is set to '0'-state.
CLK600. The clock source is an internal RC oscillator in EM ASIC N2200 (during the power-up sequence) or
RAPU SMPS Clk.
Bluetooth and WLAN have a separate 38.4MHz TCXO clock oscillator.

SIM interface
The phone has a SIM (Subscriber Identification Module) interface including a SIM connector. The connector
is only accessible when the battery is removed.
The SIM interface consists of an internal interface between RAPU and EM ASIC (N2200), and an external
interface between EM ASIC and SIM contacts.

Figure 38 SIM interface

The EM ASIC handles the detection of the SIM card. The detection method is based on the BSI line. Because of
the location of the SIM connector, removing the battery causes a quick power down of the SIM interface.
The SIM interface supports both 1.8V and 3.0V SIM cards. The SIM interface voltage is first 1.8 V when the SIM
card is inserted, and if the card does not response to the ATR (Answer to Request), a 3V interface voltage is
used.

MicroSD card interface
The microSD card interface has one internal interface between RAPU and EM ASIC and one external interface
between EM ASIC and the microSD card. The microSD card connector is mounted on a separate PWB, the Micro
PWB.

I2C bus, port 0. The camera is supplied by separate voltage regulators enabled by the camera software
(GENIOs).
Control signals to and from the camera flash driver are connected directly to RAPU (GENIOs).

Bluetooth interface
Bluetooth provides a fully digital link for communication between a master unit (the phone) and one or more
slave units (e.g. a wireless headset). Data and control interface for a low power RF module is provided by the
BTHFM module.
Bluetooth is physically integrated with FM radio in the BTHFM module ASIC, but from a functional point of
view they have nothing in common

Figure 48 Bluetooth interface

The BTHFM module is powered by VBAT and the regulated voltage VIO. For audio applications the Bluetooth
has a PCM data bus. In addition an UART (universal asynchronous receiver/transmitter) is used for data
communication and controls.
Bluetooth shares the antenna with WLAN.

RF description
Receiver (RX)
An analogue signal is received by the phone's antenna. The signal is converted to a digital signal and is then
transferred further to the baseband (e.g. to the earpiece).
The receiver functions are implemented in the RF ASIC.
Signals with different frequencies take different paths, therefore being handled by different components.
The principle of GSM and WCDMA is the same.

System Module

Transmitter (TX)
The digital baseband signal (e.g. from the microphone) is converted to an analogue signal, which is then
amplified and transmitted from the antenna. The frequency of this signal can be tuned to match the bandwith
of the system in use (e.g. GSM900).
The transmitter functions are implemented in the RF ASIC.
Even though the GSM and WCDMA signals are sent via different components, the principle of the transmission
is the same.
