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.

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 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.

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 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 blank There 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 correct Image 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 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) 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.

Bluetooth troubleshooting

Introduction to Bluetooth troubleshooting

There are two main Bluetooth problems that can occur:
Problem Description
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.

Audio troubleshooting

Audio troubleshooting test instructions

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.

Energy management calibration

Prerequisites
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.
Steps
1. Place the phone to the docking station adapter (CU-4 is connected to the adapter).
2. Start
3. Choose File Scan Product.
Phoenix
service software.
4. Choose TuningEnergy Management Calibration.
5. To show the current values in the phone memory, click Read, and check that communication between
the phone and CU-4 works.
6. Check that the CU-4 used check box is checked.
7. Select the item(s) to be calibrated.
Note: ADC calibration has to be performed before other item(s). However, if all calibrations are
selected at the same time, there is no need to perform the ADC calibration first.
8. Click Calibrate.
The calibration of the selected item(s) is carried out automatically. The candidates for the new calibration values are shown in the
calibration values seem to be acceptable (please refer to the following "Calibration value limits" table), click Write to store the new calibration values to the phone permanent memory.
