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 Ni-Cd/NiMh 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.

This section is intended to be a guide for localising and repairing electrical faults. The fault repairing is divided
into troubleshooting paths. The following main troubleshooting tree describes the different baseband
troubleshooting paths to be followed in fault situations.
• One or more keys can be stuck, so that the key does not react when a keydome is pressed. This kind of
failure is caused by mechanical reasons (dirt, corrosion).
• Malfunction of several keys at the same time; this happens when one or more rows or columns are failing
(shortcut or open connection). For a more detailed description of the keyboard and keymatrix, see section
Keyboard.
If the failure mode is not clear, start with the Keyboard Test in

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 cellular 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 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.
Operating modes of the display
Display is in a normal mode when the phone is in active use.
Display is in a partial idle mode when the phone is in the screen saver mode.
Display is in OFF mode when the phone is in the full idle mode (idle LED is flashing).
The operating modes of the display can be controlled with the help of Phoenix.
Table 10 Display module troubleshooting cases
Display blankThere is no image on the display and Idle LED does
not flash. 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 part of the
image can be missing. If part of 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) but the backlight is not, follow the
Display and keyboard backlight troubleshooting..
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 table below.
Keyboard backlights are turned ON only in dark conditions. This is controlled by the Ambient Light Sensor
(ALS). Also the brightness of the display is adjusted by the ambient light sensor.
You can enable/disable ALS with the help of Phoenix service software.
Display brightness can be adjusted manually, if ALS is disabled. If the ambient light sensor is enabled, it
adjusts the display brightness automatically.

ALS troubleshooting
Context
• If a phototransistor is broken, replace it with a typical phototransistor.
• If the phototransistor is changed, the calibration value in the phone memory has to be changed to the
default value ‘1’.
There are two main Bluetooth problems that can occur:
ProblemDescription
Detachment of the BT antenna.This would most likely happen if the device has
been dropped repeatedly to the ground. It could
cause the BT antenna to become loose or partially
detached from the PWB. (see next page for details
about BT antenna HW and Mechanics)
A malfunction in the BT ASIC, BB ASICs or Phone’s BT
SMD components.
The main issue is to find out if the problem is related to the BT antenna or related to the BT system or the
phone’s BB and then replace/fix the faulty component.
This is unpredictable and could have many causes
i.e. SW or HW related.

Product list.
In addition to JBT-9, also SB-6, JBT-3 and JBT-6 Bluetooth test boxes can be used.
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)
• Current probe (Internal handsfree DPMA output measurement)
• 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 microphone to Internal earpiece
• External microphone to Internal handsfree speaker
• Internal microphone to External earpiece
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.
Figure 9 Single-ended output waveform of the Ext_in_HP_out measurement when earpiece is connected.
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 10 Differential output waveform of the Ext_in_IHF_out out loop measurement when speaker is connected.
Energy Management (EM) calibration is performed to calibrate the setting (gain and offset) of AD converters
in several channels (that is, battery voltage, BSI, battery current) to get an accurate AD conversion result.
Hardware setup:
• An external power supply is needed.
• Supply 12V DC from an external power supply to CU-4 to power up the phone.
• The phone must be connected to a CU-4 control unit with a product-specific flash adapter.
