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-289; 276; 271 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.

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.

Figure 5 Power up timing

1 User presses the power/end key -> PWRONX is low. 2 Vilma activates Vana, VIO, VDRAM (1.8V), sleep oscillator and VR1 -> VCTCXO starts running, Digital ASIC

gets system clock, I/O buffers are powered, FLASH devices are powered. Vilma raises RstX signal to Betty.

3 Betty starts Vcore regulator immediately when RstX rises. Due to soft start this however may take up to

1 ms.

4 RF clock is stable. 5 After 16 ms Vilma releases PURX -> Digital ASICs start their boot sequence. RAP3G can switch SW controlled

regulators on/off, RAP3G controls sleeping by SleepX signal.

6 RAP3G is powered up.

Note: SleepX signal is raised at the beginning of start up procedure and it does not go to zero before

system is really ready to go to sleep. This differs from behaviour in previous generations.

Keyboard 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 is pressed. This kind of failure is caused by mechanical reasons (dirt or corrosion).

• Malfunction of several keys at the same time; this happens when one or more rows or columns are failing (shortcut or open connection).

If the failure mode is not clear, start with the Keyboard test in Phoenix.

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.

Steps

1. Verify with a working display that the fault is not on the display module itself.

The display module cannot be repaired.

2. Check that the cellular engine is working normally.

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

Taking and evaluating test pictures with main camera

When

• Avoid bright fluorescent light, 50/60Hz electrical network or high artificial illumination levels

• If the phone is hot, let it rest for a while before taking the picture

• Make sure the optical system is clean

• Use highest possible resolution

• Make sure the light is sufficient (bright office lightning)

• Do not take the picture towards light source

• Hold the phone as still as possible when taking the picture

• Pictures should be taken both at infinity ~>2m and at macro distance ~10-15 cm in order to verify auto

When

• The center of the picture is sharper than the edges

• If phone has auto focus: Remember that the white focussing frame which appears when the camera button

• The image may be blurred, though it does not show in the viewfinder

• Analyse the picture from your PC monitor, full colour setting is recommended

• If possible, compare with a picture of the same motive taken with a similar Nokia device

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. The input signal for each loop test is single-ended.

Required equipment

The following equipment is needed for the tests:

• Oscilloscope

• Function generator (sine waveform)

• 'Active speaker' or 'speaker and power amplifier'

• 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

• External 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.

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.
