ESD protection

Nokia requires that service points have sufficient ESD protection (against static electricity) when servicing the phone.

Any product of which the covers are removed must be handled with ESD protection. The SIM card can be replaced without ESD protection if the product is otherwise ready for use.

To replace the covers ESD protection must be applied. All electronic parts of the product are susceptible to ESD. Resistors, too, can be damaged by static electricity

discharge. All ESD sensitive parts must be packed in metallized protective bags during shipping and handling outside

any ESD Protected Area (EPA). Every repair action involving opening the product or handling the product components must be done under

ESD protection. ESD protected spare part packages MUST NOT be opened/closed out of an ESD Protected Area. For more information and local requirements about ESD protection and ESD Protected Area, contact your local

Nokia After Market Services representative.

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.

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.

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:

RM-412; RM-413 BB Troubleshooting

Issue 1 COMPANY CONFIDENTIAL Page 3 –7

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: 1 One or more keys are stuck, so that the key(s) does not react when you press a keydome. This kind of

failure is caused by mechanical reasons (dirt, corrosion).

2 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

Audio Troubleshooting

Audio troubleshooting test instructions

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. 1kHz sine wave from 5cm 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 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.

ALS Technical Description and Troubleshooting

Ambient Light Sensor

Figure 18 Ambient Light Sensor

Ambient Light Sensor consists of the following components:

•

Light guide

•

Ambient Light Sensor (ALS) ALS is a digital I2C interface component, having two channels with different spectral sensitivities. When

combined, the component responds to illuminance similar as human eye.

•

Vdd Filtering capacitor C1103 Ambient Light Sensor information is used to control keypad and display brightness of the phone. Keyboard backlight is turned OFF, when it’s not needed. Display brightness is dimmed, when environment

lighting is dark. Ambient Light Sensor is calibrated in production and can be re-tuned in service points though not

recommended unless calibration coefficient are lost for some reason

ALS troubleshooting

Context

Functionality check:

Steps

1. Connect phone to Phoenix and set the phone (e.g. on the table) so that the amount of ambient light seen

by ALS is as stable as possible.

2. Start Phoenix

3. Choose File -> Scan product

4. Choose Testing -> Display Test

5. Open the Lights tab, check Ambient Light Sensor check box, click Read, cover the sensor and click Read

again. When covered, Luminance reading should be less than after clicking Read without covering the sensor.

RM-412; RM-413 BB Troubleshooting

Issue 1 COMPANY CONFIDENTIAL Page 3 –43

6. If component doesn’t give any reading or reading doesn’t change when sensor is/is not covered, replace the part.

Note: After replacing the ALS. If calibration values of the new sensor are lost or for some other

reason, ALS re-tuning is required (see instructions later in this document). When doing the ALS calibration procedure, it is required to have a reference phone, which includes

calibrated ALS. ALS re-tuning instructions show why the reference phone is needed.

Re-tuning ALS

Steps

1. Connect reference phone to Phoenix and set the phone (e.g. on the table) so that the amount of ambient

light seen by ALS is as stable as possible.

2. Start Phoenix.

3. Choose File→Scan Product.

RM-412; RM-413

BB Troubleshooting

Page 3 –44 COMPANY CONFIDENTIAL Issue 1

4. Choose Tuning -> Ambient Light Sensor Calibration. You should see the following window:

5. Read AD-count values for Channel 0 and Channel 1 by click Read button and write them down.

6. Repeat 1-5 for the phone to be calibrated and make sure the phone to be calibrated is located in the

same place as reference phone was when luminance reading was taken.

7. Calculate co-efficient from reference phone and phone to be calibrated AD-count values by division: Co-

efficient = AD-count(reference phone) / AD-count(phone to be calibrated), write down the calculated coefficient values.

8. -> Iterate by changing Channel 0 and Channel 1 (reference level) values (remove cross from ‘Use default

values only’). After writing some value to Channel 0 and Channel 1 (reference value), calibrate button must be pressed. Stop iterating when Co-efficient is equal to Co-efficient calculated in step 7. Note that decimal numbers should be used in the iteration in order to achieve enough precision (e.g. 200.2455)

9. After having same Co-efficient value in “Co-efficient” textbox as the calculated value, make sure that

ambient light values (read using Testing → Display Test → “Luminance” textbox) are almost the same in reference phone and calibrated phone. Remember that illuminance readings for reference and calibrated phones must be done in the same ambient light conditions. If illuminance values differs a lot (difference max. +- 10%), repeat whole ALS re-tuning procedure.

10. To end the calibration, click Close.
