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.

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.

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.

Display module troubleshooting
General instructions for display troubleshooting
The first step is to verify with a working display that the fault is not on the display module itself. The display
module cannot be repaired.
The second step is to check that the engine is working normally. This can be done by connecting the phone
to a docking station and starting Phoenix service software. With the help of Phoenix read the phone
information to check that also the application engine is functioning normally (you should be able to read the
APE ID).
After these checks proceed to the display troubleshooting flowcharts. Use the Display Test tool in Phoenix to
find the detailed fault mode.

Pixel defects
Table 6 Display module troubleshooting cases

Display blank

There is no image on the display. The display looks
the same when the phone is on as it does when the
phone is off. The backlight can be on in some cases.

Image on the display not correct

Image 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 appropriate
troubleshooting diagram.

Backlight dim or not working at all

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. Backlight is also
controlled automatically by the ambient light
sensor.
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.

Table 7 Pixel defects

Bright sub-pixels

picture.

Combined sub-pixel

defects are characterized by at least two sub-pixels
defects (bright or dim) being closer than 5 mm to
each other.

Temporal sub-pixels

(sometimes called blinking defects) exhibit
temporal variations not related to any steady-state
video input. Temporal sub-pixel defects may be
intermittent, exhibit a sudden change of state, or
be flickering.

Issue 4

RM-675; RM-691
BB Troubleshooting and Manual Tuning Guide
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 2 kHz.
The input signal for each loop test can be either single-ended or differential. Exception to this is a digital
microphone which needs input signal from an external sound source (laptop speaker) to playback, eg. 1 kHz
sine wave from 5 cm distance.

Required equipment
The following equipment is needed for the tests:
• Oscilloscope
• Function generator (sine waveform)
• Current probe (Internal handsfree DPMA output measurement)
• Phoenix service software
• Battery voltage 3.7V
• Sound source (laptop speaker or B&K type 4231 calibrator)

Test procedure
Audio can be tested using the Phoenix audio routings option. Three different audio loop paths can be
activated:
• External headset mic to earpiece
• External headset mic to IHF mono
• Internal digital microphone to headset
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 the following table.

Phoenix audio loop tests and test results
The results presented in the 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.

GPS troubleshooting
GPS layout and basic test points
The GPS components are located on the top side of the PWB. Satellite signals are picked up by the GPS antenna
in the B-cover. The signal is then routed through a filter before being processed by the GPS5350 receiver ASIC.

GPS settings for Phoenix

Quick Test window
This test will perform 3 tests in one: Self test, Oscillator Test and CW Test and will provide a Pass/Fail Response
for each. The HW Self Test confirms basic communication with the GPS ASIC. The oscillator test confirms the
frequency accuracy of the GPS TCXO against the Ref_Clk. The CW Test confirms end-to-end connectivity
between the GPS antenna and the GPS ASIC. It also contains a receive button.
Before this test is performed a known good phone should be tested in order to calibrate the setup. The signal
level of the Signal Generator should be adjusted so a reading of SNR 35 dB is achieved with the reference
unit. A good starting point is to set up the signal generator to -50 dBm.
These checks are part of GPS failure troubleshooting.

Figure 15 GPS Quick Test window

GPS control

Prerequisites
A flash adapter with RF coupler connected to a PC with Phoenix service software is required. The GPS signal
should be connected to the RF coupler. Calibrate the signal level with a known good phone. Signal level will
be high (approx -45dBm) because it is a leakage connection.

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.

In addition, a test of the WLAN to BTH 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 BTH 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 BTH Txconfig, BTH RF Active, BTH Priority, and BTH 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 BTH. More detailed WLAN performance test is covered in
WLAN functional test section.

WLAN functional tests

On/Off test
Prerequisites
A flash adapter connected to a PC with Phoenix service software is required.
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 190 to 220mA. 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
Prerequisites
Connect complete phone assembly with battery cover to a PC with Phoenix service software using a USB data
cable.
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 Monitor the WLAN TX spectrum on a Spectrum analyser. (When making a radiated test ensure that other
WLAN devices are not transmitting as these may be detected as well, confusing the result). A typical
11MBPS TX spectrum is shown in figure below.
2 To finish the test select the Finish option button.
The difference between the two readings should be approximately 150mA and measures the transmit current
in 11MBPS, 802.11b mode of operation.

RX Tests
Prerequisites
Connect complete phone assembly with battery cover to a PC with Phoenix service software using a USB data
cable.
There are different options available for testing the Rx path. The simplest is to use the WLAN to report Rx
packets when operating in an area where there is an active WLAN network. Simply starting an Rx test will
show the number of packets detected by the WLAN module as it monitors the network. However, it does
require a properly configured WLAN network.

Troubleshooting flow

FMTx troubleshooting
General
The handset uses the metallic battery cover as FMTX antenna. The connection to the antenna is exposed by
disassembling the phone and removing the PWB.
The antenna requires two connection points, a signal contact spring which contacts the battery cover and
the contact pad on the main PWB (X6000), and a grounding pogo pin (connecting the FMTX antenna to a
small FMTX PCB inserted into the UI chassis). Both the spring and pogo pin are assembled on the B-cover. It
is important to check these connection points for damage or dirt since the performance of the FMTx
implementation will be severely impaired if these connections are not in good condition.

General visual inspection guidelines
• Check the condition of the antenna spring, pogo pin and contact pads.
• Check that the N6300 device is placed correctly on the PWB and that there are no obvious signs of damage.
• Check the surrounding components and ensure correct placement on the PWB and that there is no visual
damage. Check that there are no missing components.

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).

Measuring equipment
All measurements should be done using:
• An oscilloscope for low frequency and DC measurements. Recommended probe: 10:1, 10Mohm//8pF.
• A radio communication tester including RF generator and spectrum analyzer, for example Rohde & Schwarz
CMU200. (Alternatively a spectrum analyzer and an RF generator can be used. Some tests in this guide are
not possible to perform if this solution is chosen).
Note: A mobile phone transmitter should never be tested with full TX power (it is only possible to
perform the measurements in a good RF-shielded room). Even low power transmitters may disturb
nearby networks and cause problems to 3G cellular phone communication in a wide area.
Note: All communication Test Set Screen dumps are from CMU200. Other testers are different.
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.

RF tuning and testing
RF auto tuning and testing with Nokia Care Suite

Introduction to cellular RF tunings
RM-675 cellular RF engine has been tuned correctly in production. There is no reason to do re-calibration
unless one or more of the RF components are changed or memory (D3000) is corrupted.
RM-675 can be tuned automatically. Auto tuning is designed to align the phone's RF part easily and faster. It
performs calibrations, tunings and measurements of RX and TX. The results are displayed and logged in a
result file, if initiated.
Note: Always perform RF tuning with the help of the module jig MJ-277, never with RF couplers.
Using an RF coupler in the tuning phase will cause a complete mistuning of the RF part.
Important: After RF component changes, always perform cellular RF auto tuning.

Cable and adapter losses
RF cables and adapters have some losses. They have to be taken into account when the phone is tuned. As
all the RF losses are frequency dependent, the user has to act very carefully and understand the measurement
setup. For RF attenuations of the CA-181RS RF cable, please refer to section 'Service Tools and Service
Concepts'.

Hardware set up
For hardware requirements for auto tuning, please refer to RF testing and BB/RF tuning concept with module
jig in section 'Service Tools and Service Concepts'.

Nokia Care Suite preparations
Install Testing And Tuning Tool add-on application to Nokia Care Suite. Automatic RF testing and tuning is
not possible without this application. There is no more support in Phoenix to auto tune RM-675 product.
Install the phone specific data package, for example Nokia_firmware_RM-675_EUROPE_10.014_v41.0.exe. This
defines phone specific settings.

RF auto tuning procedure
Note: If RF splitter is in use, skip steps 10, 11 and 12.
1

Make sure the phone (in the module jig) is connected to the PC.

Connect the RF cable between the phone (low band antenna connector) and the communication tester.
If an RF splitter is in use, connect both low and high band antenna cables.

Self test troubleshooting
Troubleshooting with RF Self tests

Context
Linko (N7512) RF ASIC contains test structures that can be used to detect certain RF related errors. In order
to use these self tests the most efficient way, it is very important that the tests are performed in a certain
order, or at least that the error data is analyzed in this order. The tests are designed so that by going through
them in this order it is easy to find the problem component without any redundant checks. The flowchart
presented in this document is based on that idea.
The testing order recommended and used in this troubleshooting guide is the following:
1 ST_CDSP_RF_BB_IF test (86)
• Tests the functionality of the BB/Linko serial interface & Reset lines.
• If this test fails, it means that there is a problem in programming of the N7512 and all of the following
tests cannot give correct data.
2 ST_CDSP_STROBE_TEST (124)
• Tests the functionality of the RFStrobe signal.
3 ST_CDSP_DIGI_RXTX_IF_TEST (125)
• Test checks that the digital RX and TX lines between BB and N7512 are properly connected.
4 ST_CDSP_TX_WCDMA_POWER_TEST (75)
• Checks the output power of the WCDMA transmitter.
5 ST_CDSP_RF_SUPPLY_TEST (83)
• Tests the functionality of N7512 bias block, regulators, reference voltage line and, supply connections.
• If these fail, all other N7512 tests can/will fail.
6 ST_CDSP_PA_ID_PIN_TEST (127)
• The purpose of this test is to identify the PAs of the different vendors.
To get the best out of these instructions you need to have the valid schematics at hand.

Transmitter troubleshooting
General instructions for 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 Controls”, in WCDMA transmitter testing
the best tool is “TX Control”.
• Remember that re-tuning is not a fix! Phones are tuned correctly in production.
Note: Never activate the GSM or WCDMA transmitter without a proper antenna load. Always connect
a 50 Ω load to the RF connector (antenna, RF-measurement equipment or at least a 2 W dummy
load); otherwise the GSM or WCDMA Power amplifier (PA) may be damaged.

GSM transmitter troubleshooting

Steps
1. Set the phone to local mode.
2. Activate RF controls in Phoenix ( Testing → GSM → Rf Controls ).

Cellular RF Troubleshooting
The cellular antenna covers the GSM and WCDMA bands and has separate antenna feeds for low and high
band. Connection is implemented by C-clips (3pcs). The main antenna consists of an LDS (plating on plastic)
antenna module, an antenna PWB and two coax cables. It is located at the bottom of the B-cover.
The GPS and BT/WLAN antennas are placed on one plastic carrier at the top of the phone. The GPS antenna
is located on the right-hand side (volume key side) and the BT/WLAN antenna on the left-hand side (charger
side). Both antennas are connected to the main PWB by C-clips.
The NFC antenna consists of a flexi and a ferrite-sheet and is attached to the top of the B-cover with adhesive.
Connection to the main PWB is implemented by two C-clips.
The FMTX antenna is a metallic battery cover. Feeding from the PWB is implemented by a spring connection,
and the GND connection to the PWB by a pogo pin.

Main antenna functionality
The main antenna is functioning normally when the feed and GND pads take proper contact to the contact
springs on the PWB, and the antenna plated tracks are visually intact.
The main antenna functionality must also be checked by measuring the transmitted power with RF coupler
at GSM900 channel 124 for low band and at GSM1900 channel 661 for high band.

Antenna troubleshooting

Antenna contacts, visual check
The main antenna has three C-clips on the antenna PCB for connections, visually check that they take proper
contact to the antenna pattern.
The main antenna has two coax cables for connection to the main PWB, check the cable connectors for any
damage and that the receptacles on the PWB are clear.
Check that the BT/WLAN, GPS and NFC antenna pads take proper contact to the C-clips on the PWB and the Cclips are clearly open.
Check that the FMTX feed spring and pogo pin are clearly open, and take proper contacts to the PWB and
battery cover. Check that the contact pads on the PWB are clear.

Introduction to camera module troubleshooting

Background, tools and terminology
Faults or complaints in camera operation can be roughly categorised into three subgroups:
1 Camera is not functional at all; no image can be taken.
2 Images can be taken but there is nothing recognizable in them.
3 Images can be taken and they are recognizable but for some reason the quality of images is seriously
degraded, or customer complains about image quality.
Image quality is very hard to measure quantitatively, and even comparative measurements are difficult
(comparing two images) to do, if the difference is small. Especially if the user is not satisfied with his/her
device's image quality, and tells, for example, that the images are not sharp, it is fairly difficult to accurately
test the device and get an exact figure which would tell whether the device is functioning properly.
Often subjective evaluation has to be used for finding out if a certain property of the camera is acceptable
or not. Some training or experience of a correctly operating reference device may be needed in order to
detect what actually is wrong, or is there anything wrong at all.
It is easy for the user to take bad images in bad conditions. Therefore the camera operation has to be checked
always in constant conditions (lighting, temperature) or by using a second, known-to-be good device as
reference. Experience helps significantly in analysing image quality.

Terms
Digital zoom

Digital zoom is done by first cropping the image by the zoom ratio and
then upscaling it to the output resolution. This will decrease the image
quality especially with high zoom ratios.

Dynamic range

Camera's ability to capture details in dark and bright areas of the scene
simultaneously.

Exposure time

Camera modules use silicon sensor to collect light and for forming an
image. The imaging process roughly corresponds to traditional film
photography, in which exposure time means the time during which the
film is exposed to light coming through optics. Increasing the time will
allow for more light hitting the film and thus results in brighter image. The
operation principle is exactly the same with silicon sensor, but the shutter
functionality is handled electronically i.e. there is no mechanical moving
parts like in film cameras.

Flicker

Phenomenon, which is caused by pulsating in scene lighting, typically
appearing as wide horizontal stripes in an image.

Noise

Variation of response between pixels with same level of input illumination.

Resolution

Usually the amount of pixels in the camera sensor. In some occasions the
term resolution is used for describing the sharpness of the images.

Sensitivity

Camera module's sensitivity to light. In equivalent illumination conditions,
a less sensitive camera needs a longer exposure time to gather enough
light in forming a good image. Analogous to ISO speed in photographic
film.

Camera Module Troubleshooting
Sharpness

Good quality images are 'sharp' or 'crisp', meaning that image details are
well visible in the picture. However, certain issues, such as non-idealities
in optics, cause image blurring, making objects in picture to appear 'soft'.
Each camera type typically has its own level of performance.

The effect of image taking conditions on image quality
There are some factors, which may cause poor image quality, if not taken into account by the end user when
shooting images, and thus may result in complaints. The items listed are normal to camera operation and
are not a reason for changing the camera module.

The amount of light available
In dim conditions camera runs out of sensitivity. The exposure time is long (especially in the night mode)
and the risk of getting shaken (= blurred) images increases. In addition, image noise level grows. The
maximum exposure time in the night mode is ¼ seconds. Therefore, images need to be taken with extreme
care and by supporting the phone when the amount of light reflected from the target is low. Because of the
longer exposure time and larger gain value, noise level increases in low light conditions. Sometimes blurring
may even occur in daytime, if the image is taken very carelessly. See the figure below for an example. This
is normal; do not change the camera module.

Figure 24 Blurring caused by shaking hands

Movement in bright light
If an image is taken of moving objects or if the device is used in a moving vehicle, object 'skewing' or 'tilting'
may occur. This phenomenon is fundamental to most CMOS camera types, and may happen when using the
electronic shutter. The movement of camera or object sometimes cause blurring indoors or in dim lighting
conditions because of long exposure time. This is normal; do not change the camera module.

Figure 25 Near objects get skewed when taking images from a moving vehicle

Temperature
High temperatures inside the mobile phone cause more noise to appear in images. For example, in +70
degrees (Celsius), the noise level may be very high, and it further grows if the conditions are dim. If the phone
processor has been heavily loaded for a long time before taking an image, the phone might have considerably
higher temperature inside than in the surrounding environment. This is also normal to camera operation;
do not change the camera module.

Figure 26 Noisy image taken in +70 degrees Celsius

Phone display
If the display contrast is set too dark, the image quality degrades: the images may be very dark depending
on the setting. If the display contrast is set too bright, image contrast appears bad and "faint". This problem
is solved by setting the display contrast correctly. This is normal behaviour; do not change the camera module.

Basic rules of photography (especially shooting against light)
Because of dynamic range limitations, taking images against bright light might cause either saturated image
or the actual target appear too dark. In practice, this means that when taking an image indoors and having,
for example, a window behind the object, the result is usually poor. This is normal behaviour; do not change
the camera module.

Figure 27 Image taken against light

Flicker
In some occasions a bright fluorescent light may cause flicker in the viewfinder and captured image. This
phenomenon may also be a result, if images are taken indoors under the mismatch of 50/60 Hz electricity
network frequency. The electricity frequency used is automatically detected by the camera module. In some
very few countries, both 50 and 60 Hz networks are present and thus probability for the phenomenon
increases. Flickering occurs also under high artificial illumination level. Flickering only occurs when the rolling
shutter is used. This is normal behaviour; do not change the camera module.

Figure 28 Flicker in an image; object illuminated by strong fluorescent light

Bright light outside of image view
Especially the sun can cause clearly visible lens glare phenomenon and poor contrast in images. This happens
because of undesired reflections inside the camera optics. Generally this kind of reflections are common in
all optical systems. This is normal behaviour; do not change the camera module.

Image quality analysis
Possible faults in image quality
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
may be expected to appear:
• Dust (black spots)
• Lack of sharpness
• Bit errors
In addition, there are many other kinds of possibilities for bad image quality, but those are ruled out from
the scope of this document since the probability of their appearance is small.

EDoF impact on image quality
This phone uses EDoF (Extended Depth of Field) technology for its main camera. The technology differs from
AF and fixed focus cameras.
With EDoF technology, both near and far objects will be sharp and in focus. A key limitation is that objects
closer than 50 cm to the camera will not be in focus and there is no macro mode.
Field returns are possible if users do not understand why objects closer than 50 cm are not in focus. This can
easily be verified by capturing an image 50 cm from the camera and checking if it is in focus.

Testing for dust in camera module

Symptoms and diagnosis
For detecting these kinds of problems, take an image of a uniform white surface and analyse it in full
resolution. A good quality PC monitor is preferred for analysis. Search carefully, since finding these defects
is not always easy. Figure "Effects of dust on optical path" is an example image containing easily detectable
dust problems.
When taking a white image, use uniformly lightened white paper or white wall. One possibility is to use
uniform light but in this case make sure that the camera image is not flickering when taking the test image.
In case flickering happens, try to reduce illumination level. Use JPEG image format for analysing, and set the
image quality parameter to ‘High Quality’.
Black spots in an image are caused by dirt particles trapped inside the optical system. Clearly visible and
sharp edged black dots in an image are typically dust particles on the image sensor. These spots are searched
for in the manufacturing phase, but it is possible that the camera body cavity contains a particle, which may
move onto the image sensor active surface, for example, when the phone is dropped. Thus it is also possible
that the problem will disappear before the phone is brought to service. The camera should be replaced if the
problem is present when the service technician analyses the phone.
If a dust particle is lying on the infrared filter surface on either side, they are hard to locate because they are
out of focus, and appear in the image as large, grayish and fading-edge 'blobs'. Sometimes they are invisible
to the eye, and thus the user probably does not notice them at all. However, it is possible that a larger particle
disturbs the user, causing need for service.

Figure 32 Effects of dust on optical path

If large dust particles get trapped on top of the lens surface in the cavity between camera window and lens,
they will cause image blurring and poor contrast. The dust gasket between the window and lens should
prevent any particles from getting into the cavity after the manufacturing phase.
If dust particles are found on the sensor, this is classified as a manufacturing error of the module and the
camera should be replaced. Any particles inside the cavity between the protection window and lens have
most probably been trapped there in the assembly phase at a Nokia factory. Unauthorized disassembling of
the product can also be the root of the problem. However, in most cases it should be possible to remove the
particle(s) by using clean compressed air. Never wipe the lens surface before trying compressed air; the
possibility of damaging the lens is substantial. Always check the image sharpness after removing dust.

Testing camera image sharpness

Symptoms and diagnosis
If pictures taken with a device are claimed to be blurry, there are four possible sources for the problem:
1 The protection window is fingerprinted, soiled, dirty, visibly scratched or broken.
2 User has tried to take pictures in too dark conditions and images are blurred due to handshake or
movement. This is not a cause to replace camera module.
3 There is dirt between the protection window and the camera lens.
4 The protection window is defective. This can be either a manufacturing failure or caused by the user. The
window should be changed.
A quantitative analysis of sharpness is very difficult to conduct in any other environment than optics
laboratory. Therefore, subjective analysis should be used.
If no visible defects (items 1-4) are found, a couple of test images should be taken. Generally, a wellilluminated typical indoor scene, such as the one in Figure "Good image taken indoors", can be used as a
target. The main considerations are:
• The protection window has to be clean.
• The amount of light (300 – 600 lux (bright office lighting)) is sufficient.
• The scene should contain, for example, small objects for checking sharpness. Their distance should be 1
– 2 meters.
• If possible, compare the image to another image of the same scene, taken with a different device. Note
that the reference device has to be a similar Nokia phone.

Camera Module Troubleshooting
The taken images should be analysed on PC screen at 100% scaling simultaneously with a reference image.
Pay attention to the computer display settings; at least 65000 colors (16 bit) have to be used. 256 (8-bit)
color setting is not sufficient; true color (24 bit, 16 million colors) or 32 bit (full color) setting is recommended.
If the differences are noticeable at a glance and also if the one under investigation is significantly inferior,
the module might have a faulty lens. In this case, the module should be changed. Always re-check the
resolution after changing the camera module. If a different module produces a clearly noticeable quality gap,
the fault is probably in the camera window. Check the window by looking carefully through it when replacing
the module. As references Figure "Good image taken indoors" and Figure "Good image taken outdoors" can
be used. Another possibility is to use a service point comparison phone, if available.

Effects of dirty or defective camera lens protection window
The following series of images demonstrates the effects of fingerprints on the camera protection window.
Note: The effects of any dirt in images can vary very much; it may be difficult to judge if the window
has been dirty when some image has been taken or if something else has been wrong. That is why
the cleanness of the protection window should always be checked and the window should be wiped
clean with a suitable cloth.

RM-675; RM-691
Camera Module Troubleshooting
Bright point light sources might cause images that have flares around the light source if the protection
window is dirty. A smeared fingerprint may be hard to see on the protective window but if will affect the
image quality. These flares can be avoided by cleaning the window with a suitable cloth.

Figure 35 Image of point light sources taken with a clean protective window

Figure 36 Image of point light sources taken with a dirty (finger print) protective window

Faulty pixels in images
Faulty pixels are pixels that do not respond to light in the same way as the pixels around them. There are
three main types of faulty pixels, dead, stuck and hot pixels.
Dead pixels are always black or significantly darker than their surrounding. Dead pixels appear as black spots
in all lightning conditions. Camera modules producing images with dead pixels that are clearly noticeable
should be replaced.
If the pixel remains always saturated to its maximum value it is stuck. Stuck pixels may appear as red, green,
blue or white spots in all lightning conditions. Camera modules producing images with one or more stuck
pixels should be replaced.
Hot pixels are pixels that easily saturate in dim light conditions. It is normal to get a lot of noise and hot
pixels in night conditions or otherwise dark conditions. The hot pixels should disappear when the ambient
light is increased, but may still appear in darker areas of an otherwise well illuminated scene.

When examining an image for defect pixels, test images should be viewed as 100% enlargements on a PC
monitor.

Figure 37 Enlargement of a hot pixel

Flash photography problems
Use of flash device may affect the image in many ways.
• White balance errors. The image may get a wrong tone due to mixing of flash colour temperature and
ambient lightning. This is unwanted but normal feature.
• Dust reflections. Dust or water drops in front of the flash unit may reflect strongly to the camera sensor.
See the following figure.

Energy management
Battery and charging

BL-5K battery
The phone is powered by a 3-pole BL-5K battery 1200 mAh battery. The three poles 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 39 Battery pin order

The battery temperature is estimated by measuring separate temperature NTC resistor via the BTEMP line of
EM ASIC N2200. This is located on the main PWB, near the battery connector.

Battery connector
The battery connector is a blade connector. It has three blades;
• BSI (Battery size indicator)
• GND (Ground)
• VBAT (Battery voltage)

Figure 40 Blade battery connector

Charging
The phone is charged through the 2 mm Nokia standard interface charger plug. Charging is controlled by
dynamo charging IC BQ24156 (N3350). Dynamo charger detection is handled by EM ASIC (N2200) and external
components are needed to protect the baseband module against EMC, reverse polarity and transient
frequency deviation. For charger detection, a pulse of duration 15ms is sent to EM ASIC via V3370 MOSFET.

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-5K 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.
The PWRONX line cannot be detected when SW hangs. For that reason, the user has to remove the battery.

Modes of operation
Mode

Description

NO_SUPPLY

(Dead) mode means that the main battery is not present or its voltage is too low (below
N2200 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 is adequate
and the 32 kHz oscillator is running.

PWR_OFF

In this mode (warm), the main battery is present and its voltage is over N2200 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 32 kHz clock to count
the RESET 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.

SIM interface
The phone has a SIM (Subscriber Identification Module) interface including a SIM connector.
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 41 SIM interface

As the phone does not have a traditional battery cover due to semi-fixed battery concept, the SIM card can
be removed and inserted without removing the battery. For safe SIM card functionality, a new Puzzle pushpush SIM reader with card detection and removal pre-warning switches is used.
Pre-warning and card detect signals are connected together in the Puzzle layout symbol, so there is only one
switch connection in the schematics symbol. The combined switch signal is connected through an inverter
to Gazoo/Pearl SimDetX input. The following figure shows the principle of SIM circuitry with the Puzzle.

System Module

Figure 42 Puzzle SIM connector circuitry

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), 3V interface voltage is
used.

Device memory
The memory components of the device are internal COMBO POP4 2Gb DDR + 8Gb M3 (NAND), a card reader for
MicroSD, and 8GB eMMC memory which is non-removable and internal to the phone.
The MicroSD is used as a user’s data storage memory. The µSD card is connected to RAPU via EM ASIC which
has an internal level shifter with an ESD protection filter. The μSD card door state is detected by a detect
switch connected to RAPU Genio25. When the door is open, the uSD card is powered off. Hot swap is supported,
which means that the card may be plugged in/out at any time, without removing the battery.
The device uses 8GB eMMC (D3200) external memory. The eMMC interface is a 6-wire serial/parallel data bus
which includes a clock (CLK), 4 data signals (DAT), and command (CMD) wires. The eMMC interface is completely
formed of the GENIOs of RAPU. The eMMC consists of an internal NAND controller and an MMC controller for I/
O interface. It is a dual supply device which requires VCC of 2.9V for the NAND core and VCCQ of 1.8V for the
MMC I/O interface.

BOB1.0M-b module
The BOB1.0M-b module provides full 802.11b,g & n WLAN, BT 2.1 + EDR, FM RDS and FM TX connectivity.

BOB is the name given to a generic technology release that combines WLAN, Bluetooth, FM Rx and FM TX radio
on a single monolithic IC. The phone uses BOB1.0M-b module that consists of a single chip transceiver WL1271,
plus a separate RF front end (FE) device. The BOB1.0M-b release operates in the 2.4GHz (ISM) and the
76-108MHz FM bands.

Figure 43 BOB1.0M-b module block diagram and application circuit

From a troubleshooting point of view, WLAN is tested separately, but BTH, FMRX and FMTX are checked in
parallel.
REFOUT_EXT1 single ended 38.4 MHz analog clock from Linko RF is provided to BOB1.0M-b. The clock request
for the reference clock in the BOB1.0M-b module is shared between WLAN and BTHFM blocks. When either
system requires a clock, this signal will be active. The CLK_REQ is connected to ExtSysClkReq pin of RAPU. The
SLEEPCLK input of 32.768 KHz clock from EM ASIC is used for power management and for FM in low power
mode.
The internal SMPS supplies the whole BOB1.0M-b solution from the phone battery supply, VBAT, apart from
VIO, which is needed for interface signal reference levels.

Charger interface
The charger interface is a 2 mm Dynamo charger plug. Older chargers with a 3.5 mm plug are supported via
the charger adapter cable CA-44.
Charging is controlled by EM ASIC. Additional external components are needed for EMC purposes, reverse
polarity and transient protection of the input to the baseband module.

Figure 48 Charger interface

User interface
Touch module
This phone uses Atmel capacitive touch solution.
The Atmel touch module is interfaced to I2C0 bus of RAPU via level shifter (N2500). RAPU’s GenIO123 is used
for Touch INT.
The Atmel touch module uses VAUX1 for its analogue supply and VIO for its digital supply. Communication
with RAPU is via Symbian I2C bus.
Whenever the user touches the touch screen, the controller raises an interrupt to RAPU which initiates I2C
transactions to identify the locations the user touches on the display.

Figure 49 Touch module interface

Proximity sensor and ambient light sensor
This phone uses a combined proximity and ambient light sensor called DiPro.
The proximity part of the device uses an external IR LED supplied by VBAT. The current this LED consumes is
controlled by DiPro and set using software. The interrupt output of DiPro changes state when the infra red
light from the LED is reflected back by a suitable reflective surface.
The ambient light sensor detects the level of ambient light and adjusts the display and key brightness
accordingly whenever the display is active. Covering this sensor results in dimmed display and key lights.

The front end module called QuBBE contains the needed front end filters and the switches. QuBBE contains:
• 3 duplexers (Band II, V, VIII)
• 1 triplexer (Band I, IV)
• 12 switches with the control
• Low and high band GSM TX low bass filters
• 50 ohms low and high and antenna interface
The control signals for the switches come from Älli.

Receiver (RX)
Linko RF has higher integration level compared to previous RF generations and especially more digital design
blocks have been integrated to Älli, RF Asic.
Älli contains the receiver chain from LNAs to digital base band interface. Digital RX baseband interface
contains four data and one clk signals. The data rate and clock frequency depend on the use case.
The main blocks in Älli are:
• LNAs: Balanced inputs for 850, 900, 1800, 1900, 2100 bands
• Passive mixer
• Analog baseband: Programmable for different modes
• ADC: Programmable Sigma Delta Modulator topology ADC
• RX Digital Front End (RXDFE): Contains for example digital filtering, DC offset compensation, wide/
narrowband power measurement blocks
There is integrated external LNA matching on the bands 900, 1800, 1900 and 2100. On 850 band, there is an
integrated matching.

Synthesizer
The synthesizer has separate highly integrated 4GHz VCOs for RX and TX. The integrator capacitors of the loop
filter are outside of the IC. The PLLs are fractional type of dividers.
The reference oscillator is an on-chip 38.4 MHz digitally controlled oscillator. The 38.4 MHz crystal is outside
of Älli. DCXO delivers the internal clock to Älli, differential clock signal to BB, and two single mode clock signals
to NCW modules. Älli delivers a clk signal to diversity RX. The oscillator is controlled via RFBus with AFC signal.
Temperature compensation of the oscillator is running by the SW in Älli. The temperature sensor itself is
outside of Älli.

Transmitter (TX)
The main features of Linko1 transmitter are:
• Common PA for GSM and WCDMA
• High and low band signal paths
• Low band: 824 - 915 MHz
• High band: 1710 - 1980 MHz
• Two operation modes in PA
• Saturation mode in GMSK usage
• Linear mode in Edge and WCDMA usage
• No TX filter between PA and Älli

• Digital interface to baseband
• WCDMA mode
• Digital IQ interface
• 3 data and 1 clk signals
• GSM mode
• GSM TX data bits are sourced from baseband via RFBus to Älli
In GMSK mode, the output level of Älli is kept high with all power levels, and the output power is adjusted
by altering the collector voltage of PA. In practice, the output level of Älli is also slightly changed (optimized)
in the highest power level to keep the PA compression level more constant, which results in better overall
efficiency and performance.
In WCDMA and EDGE mode, the output power is tuned by output level of Älli. The supply voltage in WCDMA
mode is adjusted in power levels to optimize the current consumption.
