Warnings and cautions

Warnings

•

IF THE DEVICE CAN BE INSTALLED IN A VEHICLE, CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED WITH ELECTRONIC ENGINE MANAGEMENT SYSTEMS AND ANTI-SKID BRAKING SYSTEMS. UNDER CERTAIN FAULT CONDITIONS, EMITTED RF ENERGY CAN AFFECT THEIR OPERATION. IF NECESSARY, CONSULT THE VEHICLE DEALER/ MANUFACTURER TO DETERMINE THE IMMUNITY OF VEHICLE ELECTRONIC SYSTEMS TO RF ENERGY.

•

THE PRODUCT MUST NOT BE OPERATED IN AREAS LIKELY TO CONTAIN POTENTIALLY EXPLOSIVE ATMOSPHERES, FOR EXAMPLE, PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC.

•

OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLULAR TELEPHONES, MAY INTERFERE WITH THE FUNCTIONALITY OF INADEQUATELY PROTECTED MEDICAL DEVICES. CONSULT A PHYSICIAN OR THE MANUFACTURER OF THE MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS. OTHER ELECTRONIC EQUIPMENT MAY ALSO BE SUBJECT TO INTERFERENCE.

•

BEFORE MAKING ANY TEST CONNECTIONS, MAKE SURE YOU HAVE SWITCHED OFF ALL EQUIPMENT.

Cautions

•

Servicing and alignment must be undertaken by qualified personnel only.

•

Ensure all work is carried out at an anti-static workstation and that an anti-static wrist strap is worn.

•

Ensure solder, wire, or foreign matter does not enter the telephone as damage may result.

•

Use only approved components as specified in the parts list.

•

Ensure all components, modules, screws and insulators are correctly re-fitted after servicing and alignment.

•

Ensure all cables and wires are repositioned correctly.

•

Never test a mobile phone WCDMA transmitter with full Tx power, if there is no possibility to perform the measurements in a good performance RF-shielded room. Even low power WCDMA transmitters may disturb nearby WCDMA networks and cause problems to 3G cellular phone communication in a wide area.

•

During testing never activate the GSM or WCDMA transmitter without a proper antenna load, otherwise GSM or WCDMA PA may be damaged.

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-576; RM-577 ESD protection

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.

Issue 1 COMPANY CONFIDENTIAL Page vii

RM-576; RM-577

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.

Conformal coating

Difference Reading instructions

Some RM-576 units have extra conformal coating on the main PWB, which rules out exchanging certain components.

This chapter describes the RM-576 unit without extra conformal coating. The troubleshooting flows affected by extra conformal coating are available in chapter 6.

Non-repairable components

The marked components are not repairable, due to single piece shielding cans, high risk areas or coating/ underfilling of components.

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.

7. Calculate co-efficient from reference phone and phone to be calibrated AD-count values by division: Coefficient = AD-count(reference phone) / AD-count(phone to be calibrated), write down the calculated coefficient values.

8. -> Iterate by changing Channel 0 (reference level) value (remove cross from ‘Use default values only’). After writing some value to Channel 0 (reference value), calibrate button must be pressed. Stop iterating when Co-efficient is equal to Co-efficient calculated in bullet 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.

Camera module troubleshooting

Introduction to camera troubleshooting

Bad conditions often cause bad pictures. Therefore, the camera operation has to be checked in constant conditions or by using a second, known-to-be-good Nokia device as reference. Image quality is hard to measure quantitatively, and the difference between a good and a bad picture can be small. Some training or experience may be needed to detect what is actually wrong.

When checking for possible errors in camera functionality, knowing what error is suspected significantly helps the testing by narrowing down the amount of test cases. The following types of image quality problems are common:

•

Dust (black spots)

•

Lack of sharpness

•

Bit errors

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)

•

'Active speaker' or 'speaker and power amplifier'

•

Sound level meter

•

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 right Internal handsfree speaker

•

External microphone to left Internal handsfree speaker

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 a table in the following section.

Phoenix audio loop tests and test results

The results presented in this 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.

Acoustics troubleshooting

Introduction to acoustics troubleshooting

Acoustics design ensures that the sound is detected correctly with a microphone and properly radiated to the outside of the device by the speaker. The acoustics of the phone include three basic systems: earpiece, integrated handsfree (IHF) and microphone.

The sound reproduced from the earpiece eradiates through a single hole on the front cover (A-cover). The sound reproduced from the IHF speaker radiates from the sound hole located on the back side on the top part of the phone. The inlet for the microphone is found in the bottom.

For a correct functionality of the phone, all sound holes must be always open. When the phone is used, care must be taken not to close any of those holes with a hand or fingers. The phone should be dry and clean, and no objects must be located in such a way that they close any of the holes.
