RM-328 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.

RM-328 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-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.

Backup battery troubleshooting

Verify that the backup battery G2200 is empty (U<1V). Switch the phone on. Measure voltage of the battery when the main battery is connected to the phone and the phone is switched on. Wait a few minutes and monitor that the backup battery voltage rises. Switch off the phone, disconnect the main battery and monitor that the voltage of the backup battery decreases. Normal behaviour of the voltage is described in the figures below:
Issue 1 COMPANY CONFIDENTIAL Page 3 –11

RM-328
BB Troubleshooting and Manual Tuning Guide
If the voltage rises and falls quickly, check the back-up battery G2200 contacts for loose soldering or short­circuit, and repair or change G2200 if necessary. If the voltage stays ~0V, check resistance VBACK against GND. If there is no shortcircuit, AVILMA N2200 is faulty. Replace N2200.

Keyboard troubleshooting

Context
There are two possible failure modes in the keyboard module:
• 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, rust).
• 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.

Ambient Light Sensor troubleshooting and re-calibration

Introduction to ALS troubleshooting and re-calibration

If the Ambient Light Sensor (ALS) functionality is inoperative, check the Light to digital converter (N6502).
Page 3 –38 COMPANY CONFIDENTIAL Issue 1
Copyright © 2008 Nokia. All rights reserved.
RM-328 BB Troubleshooting and Manual Tuning Guide
If necessary, change the Light to digital converter (N6502). Also, check capacitor C6504 (100n).
Figure 23 ALS components
After replacing the ALS sensor, or if the calibration values of the sensor are lost or for some other reason, ALS calibration is required. For more information, see ALS functionality check (page 3–39) and Calibrating ALS
(page 3–40).
Note: ALS calibration is also required for Light SWAP Engines, because ALS is not factory calibrated
for Light SWAP.
When executing the ALS calibration, a reference phone that includes calibrated ALS is required. The ALS re­tuning instructions show why the reference phone is needed.
Note: Make sure that you have completed the display and keyboard backlights troubleshooting
before starting the ALS troubleshooting.
There is an Ambient Light Sensor window in the Phoenix Display Test tool, which shows the luminance value. The correct luminance in darkness is <20 lx, and in an office environment 100-2000 lx.
Note: The luminance value depends heavily on the light source and the angle of the phone against
the light source, so the values above can only be used as a rough guideline. Phoenix has an ambient light sensor calibration tool for changing the calibration values.

Ambient Light Sensor calibration

ALS functionality check
Steps
1. Connect the phone to the ambient light visible to ALS is stable. The light quide of the ALS is located on the upper part of the phone’s front cover, right next to the secondary camera.
2. Scan product on Phoenix (CTRL+R)

BB Troubleshooting and Manual Tuning Guide
4. Open the Lights tab, and check the Ambient light sensor check box. Click the Read button in order to get the reference ambient light value. Cover the sensor and click Read again. When covered, the luminance reading should be less than after clicking Read without covering the sensor.
5. If the component does not give any reading or the reading does not change when sensor is/is not covered, replace the part.
Note: The ALS module is located on the main PWB. ALS calibration must always be done when the
main PWB is changed. Also, if the ALS calibration values are lost from the phone, ALS needs to be recalibrated.
The ALS calibration procedure requires a reference phone with a calibrated ALS.
Calibrating ALS
Context
Before doing the manual ALS calibration, test the following default values: 1 Check the Use default values only box from the Ambient Light Sensor Calibration window 2 Click Write 3 Open the Display Test window 4 Read the luminance value from the Display Test window. If the luminance value differs a lot (difference
max. +- 10%) when compared to the reference phone, perform a manual ALS tuning procedure by following the instructions below.

Note: In the example graphic the reference phone values are: Channel 0=3001 and Channel 1=337
5. Repeat steps 1-4 for the phone to be calibrated.
Note: Make sure the phone to be calibrated is located in the same place as the reference phone was
when luminance reading was taken.
6. Calculate and write down co-efficient value by division:
7. To calibrate ALS, the value in the Reference Level textbox needs to be adjusted for both channels until
the Co-efficient calculated by Phoenix equals the values calculated in step 6. Click Calibrate after each try (and uncheck the Use default values only check box).
8. Calibration is done when the Co-efficient is equal to the co-efficient value calculated in step 6.
Note: Decimal numbers should be used in the iteration in order to achieve adequate precision (e.g.
200.2455)

9. Use Phoenix (TestingDisplay testLights tab) to verify the calibration by reading the luminance
value for both the reference phone and calibrated phone.
Note: Remember that the illuminance readings for the reference and calibrated phones must be
done in the same ambient light conditions. If the illuminance values differ more than +- 10%, repeat the whole ALS calibration procedure.
10. To end the calibration, click Close.
