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-Pol 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.

The following test points on the PWB help in the effective debugging and 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 blankThere 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 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 appropriate
troubleshooting diagram.
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. 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(sometimes called on-pixels or stuck-on) are
characterized by the appearance of bright/colored
pixels in, for example, black full screen picture.
Dark sub-pixels(sometimes called off-pixels, stuck-off, or black
pixels) are characterized by the appearance of dark
pixels in white, red, green, or blue full-screen
picture.
Combined sub-pixeldefects 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.

Introduction to display troubleshooting
The display module is a 640 X 480 VGA colour LCD known as 'Batura.' It connects to the main engine by a
multi-way ZIF connector. The locking lever mechanism on this connector must be carefully lifted up before
removing the LCD flexi.

The power key has a 10K pull-up resistor to VBAT and is normally high. A low level voltage should happen
when the key is pressed, and if this is long enough, the phone should turn ON if it is OFF and OFF if it is ON.
Check for mechanical damage to the outer button, stuck or misplaced gaskets, broken switch, liquid
contamination or broken solder pads or joints. Repair if possible.
Single-ended external earpiece and differential 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 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.

Phoenix service software
•
Battery voltage 3.7V

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.
Check for obvious blocked holes, magnetic filings or debris jamming the earpiece, broken gauze, misplaced
gaskets, dirty contacts. Clean, fix or replace if required.
Electrical tests using the Phoenix audio sweep, measure:
Check for mechanical jamming by foreign object, sticky vibra shaft or obvious damage.
Electrical tests using normal touchscreen haptics screenpress operation, ensure the option is activated and
Tip: Dilbert vibra drive signals are generated in N2200, so there is no point replacing D2800 to try
to fix a vibra fault.
ALS technical description and troubleshooting
Dipro ALS function
The automatic light sensor and proximity sensor functions are combined in N1100, "Dipro".
The ALS is used to change the brightness of the display and LED lighting. The proximity sensor picks up
reflected short pulses of infra-red light from LED V1100 and is used to turn the display off when in-call to
save power.
Check for the display changing brightness in different lighting, with the phone user setting adjusted
appropriately.

•
VIO on supply side of R2850 and R2851
Component check and consider replacement of:
•
C1100 VAUX2 decoupler maybe short
•
N1100 Dipro device
Tip: You can check for IR LED stuck "ON" by viewing the IR LED with a normal phone digital camera.
Re-tuning ALS
There is no need to re-tune ALS, since ALS default value will be written the first time the phone boots up.

is used. The FM RF signal is routed through a product specific FM antenna matching circuit to the phone
headset connector. The FM radio audio signal is routed to the headset connector through the BB ASIC shared
by the phone audio functions.
Bluetooth BER test
Prerequisites
JBT-9, or SB-6 Bluetooth test box (BT-box) is required to perform a BER test. If a BT-box not available Bluetooth
functionality can be checked by transferring a file to another Bluetooth phone.
Steps
1. Connect data cable to phone.
2. Start
3. Choose File → Scan Product.
Phoenix
service software.
4. Choose Testing → Bluetooth LOCALS .
5. Locate the BT-box serial number (12 digits) found in the type label on the back of the JBT-9, or SB-6
Bluetooth test box.
RF level should be varied during the test to obtain good audio signal quality
•
Connect suitable antenna to signal generator
Note: You may alternatively use a known good FM radio broadcast as a test signal.
2. Attach the Nokia headset to the phone’s AV connector.
3. Use Scroll button to autotune to the radio frequency.
4. Set volume to suitable level.
5. Check audio quality with a headset.
GPS troubleshooting
GPS layout and basic test points
The GPS components are located on the bottom side of the PWB. The GPS chip and associated components
are in a can which does not have a removable lid. Satellite signals are picked up by the GPS antenna in the
B-cover. The signal is then routed through a diplexer and then a filter before being processed by the GPS5350
receiver ASIC.

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.
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.
Context
Use the following to test GPS using Phoenix.
Steps
1. Place phone to Flash Adaptor.
2. Start Phoenix service software.
3. From the File menu, select Scan Product and check that the correct product version is displayed.
4. From the Testing menu, select GPS Control. This opens up
figure below, and enables the GPS.

Select Idle to confirm the GPS is enabled and is in idle mode; at this point all clocks should be present,
GPS_En_Reset & SleepX should be high, and Vdd_Dig, Vcc_TCXO & Vcc_PLL/VCO will be present.
Receiver On turns on all RF sections of the ASIC and so all LDOs will be on.
The Bob 1.0 module is a combined device with WLAN and Bluetooth functionality. It has a single antenna
connection and uses the CWS antenna through a diplexer. The Bob software is downloaded from the host
engine when the phone is powered on through the dedicated SPI interface. The Bob 38.4MHz clock is supplied
from the Linko engine.
