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.
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.
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
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.
Our policy is of continuous development; details of all technical modifications will be included with service
bulletins.

BB Troubleshooting and Manual Tuning Guide
User interface troubleshooting
Keyboard troubleshooting
Context
There are two possible failure modes in the keyboard module:
•
One or more keys are stuck, so that the key does not react when a keydome or a side key is pressed. This
kind of failure is caused by mechanical reasons (dirt, rust, mechanical damage, etc.)
•
Malfunction of several keys at the same time; this happens when one or more rows or columns in the key
matrix are failing (shortcut or open connection).
If the failure mode is not clear, start with the Keyboard test in Phoenix.
Image on the display not correctImage on the display can be corrupted or a part of
the image can be missing.
•
If a part of the image is missing, change the
display module.
•
If the image is otherwise corrupted, follow the
display fault troubleshooting flowchart.
Backlight dim or not working at allBacklight 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.

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.

5.Read AD-count values for Channel 0 by click Read button and write them down.
6.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.
7.Calculate co-efficient from reference phone and phone to be calibrated AD-count values by division: Co-
efficient = AD-count(reference phone) / AD-count(phone to be calibrated), write down the calculated coefficient values.
8.-> Iterate by changing Channel 0 (reference level) value (remove cross from ‘Use default values only’).
After writing some value to Channel 0 (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)
9.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.

GPS troubleshooting is broken down into two parts: general GPS failure troubleshooting and GPS basic checks
troubleshooting. The GPS failure troubleshooting flow can be followed and, where applicable, will feed into
the GPS basic checks troubleshooting flow.
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

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.
RM-632; RM-634; RM-699
BB Troubleshooting and Manual Tuning Guide
Measurement data
If a special low-pass filter designed for measuring digital amplifiers is unavailable, the measurement must be performed with a
current probe and the input signal frequency must be 2kHz.
Figure 14 Differential output waveform of the Ext_in_IHF_out out loop measurement when speaker is connected.
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 microphone.
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 inlet for the microphone is found in the bottom.
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.

Note: Local WLAN environment may affect test results, especially if there are many WLAN access
points nearby and any of them are using the same WLAN channel as SB-7. If the phone is able to see
and connect to local WLAN networks via its own inbuilt WLAN menu, then the phone is OK even if
the SB-7 can not be detected. Consider repeating the test where local networks do not interfere with
the lower strength signal of the SB-7 box.

Operating mode function.
WLAN layout and test points
The WLAN module has been optimised to achieve the smallest possible PWB area and adding test points will
compromise this layout efficiency. There is also an added risk that test point will compromise the WLAN
performance – the layout is quite sensitive and there have been EMC issues that were directly attributed to
use of test points.
The recommendation is to use no test points and use software tests in Phoenix to verify the operation of the
WLAN module. For reference, all test points provided on the schematic are summarised below.
The sequence of events during the start up of WLAN is:
1 PMEM is asserted high when Wlan module is first enabled by the Host.
2 WLAN module should respond by driving CLK REQ high to request the 38.4MHz clock.
3 Host engine turns on the 38.4MHz clock and then generates the SPI Clock to start the download of software
to the WLAN module.
Adding more test points in a product is not strictly necessary.
WLAN settings for Phoenix
Use the following to test WLAN using Phoenix:
1 Set phone into Local Mode .
2 From the File menu, select Scan Product and check that the correct product version is displayed
3 From the Testing menu, select Self Test. This opens up a Self Test dialogue box, as shown below.
Select the ST_WLAN_TEST check box as shown and then select Start button. The test turns on the WLAN, sets
up the SPI interface and then downloads the WLAN firmware into the WLAN module. During the download
the WLAN acknowledges the data blocks and so the self test is a good way to confirm that the WLAN module
is communicating with the Host. The result column will change to Passed after a few seconds if operating
properly.
RM-632; RM-634; RM-699
BB Troubleshooting and Manual Tuning Guide
In addition, a test of the WLAN to BT interface can be done by selecting the
ST_BT_WLAN_COEXISTENCE_TEST check box and selecting Start button.
This test verifies that the WLAN to BT co-existence interface signals are properly connected and there are no
open circuit or shorts on the four interface signals.
The co-existence interface comprises BT Txconfig, BT RF Active, BT Priority, and BT Frequency.
In summary these two Self tests provide a simple means of ensuring the Host engine is able to communicate
with the WLAN module and check the interface to BT. More detailed WLAN performance test is covered in
WLAN functional test section.
WLAN functional tests
On/Off test
From the testing toolbar select WLAN Configuration option. This opens the WLAN configuration dialogue
box below. Selecting the Power state option button (as indicated), the WLAN can be turned ON and OFF:
1 With Power State set to OFF, measure the dc power supply current consumption of the flash adaptor.
2 Next return the Power state to ON and re-measure the dc power supply current of the flash adaptor.
The difference between the currents in (1) and (2) should be between 160 to 200mA. When WLAN is ON, the
firmware has been downloaded and the WLAN module is in the receive state. When OFF WLAN is powered
down.
TX tests
From the testing toolbar select WLAN Tx Test option shown below. This test can be used to verify TX
configuration and functionality. The default settings are sufficient for testing the TX operation, although
other channels and data rates are equally suitable. To start the test, select the Start option button:
1 Measure and record the TX ON current consumption of the Phone/ flash adaptor.
2 Monitor the WLAN TX spectrum on a Spectrum analyser either using a co-ax cable connected to the WLAN
TX antenna port or by making a radiated test with a suitable WLAN antenna connected to the spectrum
analyser input. (When making a radiated test ensure that other WLAN devices are not transmitting as
these may be detected as well, confusing the result).
3 To finish the test select the Finish option button
4 Measure the TX OFF current consumption of the phone/flash adaptor.
