Warnings and cautions

Warnings

z 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.

z THE PRODUCT MUST NOT BE OPERATED IN AREAS LIKELY TO CONTAIN POTENTIALLY EXPLOSIVE ATMOSPHERES, FOR

EXAMPLE, PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC.

z 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.

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

Cautions

z Servicing and alignment must be undertaken by qualified personnel only. z Ensure all work is carried out at an anti-static workstation and that an anti-static wrist strap is worn. z Ensure solder, wire, or foreign matter does not enter the telephone as damage may result. z Use only approved components as specified in the parts list. z Ensure all components, modules, screws and insulators are correctly re-fitted after servicing and alignment. z Ensure all cables and wires are repositioned correctly. z 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.

z 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

RM-377

Care and maintenance

z This product is of superior design and craftsmanship and should be treated with care. The suggestions

below will help you to fulfill any warranty obligations and to enjoy this product for many years.

z Keep the phone and all its parts and accessories out of the reach of small children. z Keep the phone dry. Precipitation, humidity and all types of liquids or moisture can contain minerals that

will corrode electronic circuits.

z Do not use or store the phone in dusty, dirty areas. Its moving parts can be damaged. z 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.

z 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.

z Do not drop, knock or shake the phone. Rough handling can break internal circuit boards. z Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone. z Do not paint the phone. Paint can clog the moving parts and prevent proper operation. z Use only the supplied or an approved replacement antenna. Unauthorized 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.

Page vi COMPANY CONFIDENTIAL Issue 1

RM-377

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

RM-377

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.

 General RF troubleshooting

Introduction to RF troubleshooting

Most RF semiconductors are static discharge sensitive

ESD protection must be applied during repair (ground straps and ESD soldering irons).

Pre-baking

These parts are moisture sensitive and must be pre-baked prior to soldering:

• FEM U1001

Discrete components

In addition to the key-components, there are a number of discrete components (resistors, inductors and capacitors) for which troubleshooting is done mainly by visual inspection. Capacitors: check for short circuits. Resistors: check value with an ohm meter.

Note: In-circuit measurements should be evaluated carefully

Measuring equipment

All measurements should be done using:

• An oscilloscope for low frequency and DC measurements. Recommended probe: 10:1, 10Mohm//8pF.

RM-377

• A radio communication tester including RF generator and spectrum analyzer, for example Rohde & Schwarz

CMU200. (Alternatively a spectrum analyzer and an RF generator can be used. Some tests in this guide are not

possible to perform if this solution is chosen).

Note: A mobile phone CDMA2000 transmitter should never be tested with full TX power (only it

possible to perform the measurements in a good RF-shielded room). Even low power CDMA2000 transmitters may disturb nearby CDMA networks and cause problems to 3G cellular phone communication in a wide area.

Note: All measurements with an RF coupler should be performed in an RF-shielded environment

because nearby base stations can disturb sensitive receiver measurements. If there is no possibility to use RF shielded environment, testing at frequencies of nearby base stations should be avoided.

Level of repair

The scope of this guideline is to enable repairs at key-component level. Some key-components are not accessible, i.e. not replaceable. Please refer to the list of Non replaceable RF components.

Note: If the RF shielding can is removed (for measurement or repair), it must always be replaced with

a new one.

Introduction to receiver (RX) troubleshooting

RX can be tested by making a phone call or in FTM mode. For the FTM mode testing, use Qualcomm software. The main RX troubleshooting measurement is RSSI reading. This test measures the signal strength of the received signal. For CDMA RSSI measurements, see CDMA RX chain activation for manual measurements.

CDMA RX chain activation for manual measurement/WCDMA RSSI measurement

Prerequisites

Make the following settings in Qualcomm software and in the signal generator.

 Transmitter troubleshooting

General instructions for transmitter (TX) Troubleshooting

Please note the following before performing transmitter tests:

• TX troubleshooting requires TX operation.

• Do not transmit on frequencies that are in use!

• The transmitter can be controlled in local mode for diagnostic purposes.

• Remember that re-tuning is not a fix! Phones are tuned correctly in production

Note: Never activate the CDMA transmitter without a proper antenna load. Always connect a 50 Ω

load to the RF connector (antenna, RF-measurement equipment or at least a 2 W dummy load); otherwise the CDMA Power amplifier (PA) may be damaged.

General instructions for wireless Troubleshooting

Please note the following before performing wireless tests:

• Call box and position need to be confirmed by engineering.

• Suitable cable loss setting on call box (TEM cell or plate antenna)

• Golden provide is essential to generate cable loss.

• Remember that re-tuning is not a fix! Phones are tuned correctly in production

Note: Never activate the CDMA transmitter without a proper antenna load. Always connect a 50 Ω

load to the RF connector (antenna, RF-measurement equipment or at least a 2 W dummy load); otherwise the CDMA Power amplifier (PA) may be damaged.
