RM-243 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.

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 Ni-Cd/NiMh 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 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.

Figure 8 Charging backup battery

Figure 9 Discharging backup battery

If the voltage rises and falls quickly, check whether G2200 or C2242 is broken or short-circuited. Backup battery can be also dead. If the voltage stays ~0V, check resistance VBACK against GND. If there is no shortcircuit, AVILMA is faulty. Replace AVILMA.

Keyboard troubleshooting

Context

There are two possible failure modes in the keyboard module:

• One or more keys can be stuck, so that the key does not react when a keydome is pressed. This kind of

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

• 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 Phoenix.

Display blank There is no image on the display. The display looks

the same when the phone is on as it does when the phone is off. The backlight can be on in some cases.

Image on the display not correct Image on the display can be corrupted or a part of

the image can be missing. If a part of the image is missing, change the display module. If the image is otherwise corrupted, follow the appropriate troubleshooting diagram.

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 Bluetooth/FM Radio troubleshooting

There are two main Bluetooth problems that can occur:

Page 3 –26 COMPANY CONFIDENTIAL Issue 1

RM-243 BB Troubleshooting and Manual Tuning Guide

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.

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.

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 2kHz.

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 PWM 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

• HP 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.

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 includes three basic systems: earpiece, Integrated Hands Free (IHF) and microphone.

The sound reproduced from the earpiece readiates through a single hole on the front cover (A-cover). The sound reproduced from the IHF speaker radiates from the sound holes located on the left side of the device. Microphone is located at the bottom, next to the system connector.

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.

Energy management calibration

Prerequisites

Energy Management (EM) calibration is performed to calibrate the setting (gain and offset) of AD converters in several channels (that is, battery voltage, BSI, battery current) to get an accurate AD conversion result.

Hardware setup:

• An external power supply is needed.

• Supply 12V DC from an external power supply to CU-4 to power up the phone.

• The phone must be connected to a CU-4 control unit with a product-specific flash adapter.

Steps

1. Place the phone to the docking station adapter (CU-4 is connected to the adapter).

2. Start

3. Choose File→ Scan Product.

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:

• RFIC N7505

• Front End Module (FEM) N7520

• WCDMA PA N7540

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

Capacitors: check for short circuits. Resistors: check value with an ohm meter.

Note: In-circuit measurements should be evaluated carefully

visual inspection

Measuring equipment

All measurements should be done using:

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

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

CMU200. (Alternatively a spectrum analyser 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 WCDMA 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 WCDMA transmitters may disturb nearby WCDMA 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 without replacing the whole shield frame (i.e. not replaceable). Please refer to the list of Non-

replaceable RF components (page 4–7).

General voltage checking

Steps

1. Set up the main board in the module jig. The phone should be in local mode.

2. Check the following:

# Signal name Test point Voltage (all bands)

1 VCTCXO supply R7501 2.5 V 2 AHNEUS supply from DC/DC conv C7590 3.2 V 3 FEM supply L7510 3.9 V 4 WCDMA PA supply from DC/DC conv C7543 0 V (1.3 V* when transmitting. Settings

as in note below) 5 Vbat at WCDMA PA C7547 3.9 V 6 Supply input to DC/DC conv L7592 3.9 V

RM-243

* With these settings, the result should be 1.3 V.
