RM-424; RM-564 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-424; RM-564 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-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.

Keyboard and side keys troubleshooting

Context

There are two possible failure modes in the keyboard module:

•

One or more keys are stuck, so that the key does not react when a keydome or a side key is pressed. This kind of failure is caused by mechanical reasons (dirt, rust, mechanical damage, etc.)

•

Malfunction of several keys at the same time. This happens when one or more rows or columns in the key

matrix are failing (shortcut or open connection). If the failure mode is not clear, start with the Keyboard test in Phoenix. In this phone the keyboard is connected to D2800 I/O pins.

If a part of the image is missing, change the display module.

•

If the image is otherwise corrupted, follow the display fault troubleshooting flowchart.

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.

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.

Introduction to display and keyboard backlight troubleshooting

Display and keyboard lights are handled by Gazoo (EM ASIC) internal LED drive. It has one output pin, but two independent LED branches (display and keyboard) which can have different number of LEDs (2 to 4). Keyboard and display branch of LED network can be enabled and disabled independently from Gazoo LedCR register or using Phoenix display test program. Display LEDs are located inside the display and keyboard LEDs are on the PWB.

Ambient Light Sensor troubleshooting and re-calibration

Introduction to ALS troubleshooting and re-calibration

The Ambient Light Sensor (ALS) consists of the following components:

•

Ambient Light Sensor (N1100). ALS is a digital I2C interface component that has two channels with different spectral sensitivities. When combined, the component responds to illuminance similar as human eye.

•

Vdd filtering capacitor (C1100)

The ALS components are located at the top side of the main PWB as illustrated in the figure below.

Figure 16 ALS components

ALS information is used to control the keypad and display brightness of the phone. The keyboard backlight is turned OFF, when it is not needed. Display brightness is dimmed, when environment lighting is dark. ALS is calibrated in production and can be re-tuned in service points though not recommended unless calibration coefficient is lost for some reason.

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.

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)

3. Choose Testing→Display test.

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 calibration procedure requires a reference phone with a calibrated ALS.

Channel 0 and Channel 1, and write them down.

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 to achieve adequate precision (e.g.

200.2455)

Issue 1 COMPANY CONFIDENTIAL Page 3 –35

BB Troubleshooting and Manual Tuning Guide

9. Use Phoenix (Testing→Display test→Lights 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.
