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.

Open battery protection circuit due to short circuit during assembly
This phone is susceptible to short-circuiting of the VBAT line during display assembly due to the exposed
VBAT at the Dipro IR LED. This results in the battery protection circuit opening. The following steps will close
the battery protection circuit:
1 Remove the top end cap of the phone by removing the plastic covers and then remove the two screws.
Figure 7 Top cap removed to access VBAT test pad
2 Set power supply to 3.8 VDC with current limited to 500 mA. Put the negative side of the power supply to
the micro USB connector casing (see the black probe in the following figure) and the positive side to the
VBAT test pad (J2070) (see the red probe in the following figure). The power supply should show current
draw when the battery protection circuit closes. The phone should then power up provided the VBAT level
is high enough for SW to start up. If the phone does not power on, at this point you can plug a charger
into the phone and it should charge, and when VBAT reaches the proper level it should power on.

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 5 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.
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.
Visual defects (pixel)Pixel defects can be checked by controlling the
display with Phoenix. Use both colors, black and
white, on a full screen. R, G, B are also helpful.
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 in the following table.
Table 6 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.

Proximity sensor troubleshooting
Troubleshooting flow
ALS technical description and troubleshooting
Proximity sensor and ambient light sensor (ALS)
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 brightness accordingly whenever the display is active. Covering this sensor results in dimmed display
lights.
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.
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.

Introduction to connectivity module troubleshooting
The BOB1.0M-b module supports WLAN, BT, FMRX and FMTX. From a troubleshooting point of view, WLAN is
tested separately, but BT, 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 BT 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.
The following figure shows a top level block diagram of the BOB1.0M-b module.

The self tests run from Phoenix software are used for fault diagnosis.
If Phoenix software is not available, the functional tests with phone accessories are sufficient to verify the
functionality of Bluetooth and FM radio receiver.
If Bob1.0M-b module has been replaced, the WLAN tuning must be performed to ensure that the
output complies with ETSI/ FCC legal limits.

Prerequisites
A flash adapter (or phone data cable) connected to a PC with Phoenix service software is required.
Steps
1. Place the phone in the flash adapter or connect data cable to phone.
2. Start
3. Choose File→Scan Product.
Phoenix
service software.
4. From the Mode drop-down menu, set mode to Local.
Note: No external measurement equipment is required as the calibration is completely handled
internally. RF cable and adapter losses do not need to be taken into account while WLAN TX tuning
is proceeded.
WLAN TX has been BiP (Build in Prduction line testing) tuned correctly in production. There is no reason to
do re-calibration unless the Bob1.0M-b (N6300) is changed or memory (D3000) is corrupted.
WLAN TX can be tuned automatically with Testing and Tuning Tool. It performs calibrations and tunings of
WLAN TX. The results are displayed and logged in a result file, if initiated.
Steps
1. Place the phone in the flash adapter or connect data cable to phone.
2. Start
3. Choose File→Scan Product.
4. Choose Tuning→WLAN_TX_TUNING. See the following figure.
Phoenix
service software.
5. Select “Sub-Band 0” as indicated in the figure.
6. Click Start Power Calibration and read the result from the Result box.
7. If TXPowerCal response returns ‘Passed’ results, the WLAN TX BiP test is successful.
