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.

RM-235 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 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:

Issue 1 COMPANY CONFIDENTIAL Page 3 –7

RM-235

BB troubleshooting

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.

Display

Display features

• 2.4” Active TFT QVGA display supports up to 16,777,216 colors (320 x 240 pixels, 2.6 inches)

• Wide 160° viewing angle

• Ambient light detector to optimize display brightness and power consumption

Display troubleshooting

Context

• The display is in a normal mode when the phone is in active use.

• The operating modes of the display can be controlled with the help of 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.

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.

Issue 1 COMPANY CONFIDENTIAL Page 3 –23

RM-235

BB troubleshooting

2. Check that the cellular engine is working normally. i To check the functionality, connect the phone to a docking station. ii StartPhoenix service software. iii Read the phone information to check that also the application engine is functioning normally (you

should be able to read the Phone ID).

3. Proceed to the display troubleshooting flowcharts. Use the Display Test tool in Phoenix to find the detailed fault mode.

Before going to display troubleshooting flow make sure that engine is working and starting up correctly otherwise go to BB troubleshooting.

ALS technical description and troubleshooting

Ambient Light Sensor

Figure 14 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 C6504

Ambient Light Sensor information is used to control keypad and display brightness of the phone. Keyboard and 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.

Page 3 –34 COMPANY CONFIDENTIAL Issue 1

RM-235 BB troubleshooting

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.

Issue 1 COMPANY CONFIDENTIAL Page 3 –35

BB troubleshooting

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

RM-235

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.

GPS troubleshooting

GPS layout and basic test points

The GPS components are located under the shield can A7501. Satellite signals are picked up by the phones GPS antenna in the C-cover. The signal is then routed through a diplexer and filter before being processed by the GPS5300 receiver ASIC.

GPS control

Prerequisites

A flash adapter with RF coupler connected to a PC with Phoenix service software is required. The GPS signal should be connected to the RF coupler. Calibrate the signal level with a known good phone. Signal level will be high (approx -45dBm) because it is a leakage connection.

Context

Use the following to test GPS using Phoenix.

Steps

1. Place phone to Flash Adaptor.

2. Start Phoenix service software.

3. From the File menu, select Scan Product and check that the correct product version is displayed.

4. From the Testing menu, select GPS Control. This opens up figure below, and enables the GPS.

dialogue box, as shown in the

RM-235

Figure 19 GPS Control dialogue box

Select Idle to confirm the GPS is enabled and is in idle mode; at this point all clocks should be present, GPS_En_Reset & SleepX should be high, and Vdd_Dig, Vcc_TCXO & Vcc_PLL/VCO will be present.

Receiver On turns on all RF sections of the ASIC and so all LDOs will be on.

Quick Test window

This test will perform 3 tests in one: Self test, Oscillator Test and CW Test and will provide a Pass/Fail Response for each. The HW Self Test confirms basic communication with the GPS ASIC. The oscillator test confirms the frequency accuracy of the GPS TCXO against the Ref_Clk. The CW Test confirms end-to-end connectivity between the GPS antenna pogo pins and the GPS ASIC. It also contains a receive button.

Before this test is performed a known good RM-235 unit should be tested in order to calibrate the setup. The signal level of the Signal Generator should be adjusted so a reading of SNR 40 dB is achieved with the reference unit. A good starting point is to set up the signal generator to -45dBm.

These checks are part of GPS failure troubleshooting (page 3–48).

WLAN selftest and coexistence test in Phoenix

Prerequisites

Connect complete phone assembly with C-cover to a PC with Phoenix service software using a USB data cable. Use the following to test WLAN using Phoenix: 1 Set phone into Local Mode . 2 From the File menu, select Scan Product and check that the correct product version is displayed 3 From the Testing menu, select Self Test. This opens up a Self Test dialogue box, as shown below.

Issue 1 COMPANY CONFIDENTIAL Page 3 –49

RM-235

BB troubleshooting

Select the ST_WLAN_TEST check box as shown and then select Start button. The test turns on the WLAN, sets up the SPI interface and then downloads the WLAN firmware into the WLAN module. During the download the WLAN acknowledges the data blocks and so the self test is a good way to confirm that the WLAN module is communicating with the Host. The result column will change to Passed after a few seconds if operating properly.

In addition, a test of the WLAN to BTH interface can be done by selecting the ST_BT_WLAN_COEXISTENCE_TEST check box and selecting Start button.

This test verifies that the WLAN to BTH co-existence interface signals are properly connected and there are no open circuit or shorts on the four interface signals.

The co-existence interface comprises BTH Txconfig, BTH RF Active, BTH Priority, and BTH Frequency.

In summary these two Self tests provide a simple means of ensuring the Host engine is able to communicate with the WLAN module and check the interface to BTH. More detailed WLAN performance test is covered in WLAN functional test section.

WLAN functional tests

On/Off test

Prerequisites

A flash adapter connected to a PC with Phoenix service software is required. From the testing toolbar select WLAN Configuration option. This opens the WLAN configuration dialogue

box below. Selecting the Power state option button (as indicated), the WLAN can be turned ON and OFF: 1 With Power State set to OFF, measure the dc power supply current consumption of the flash adaptor. 2 Next return the Power state to ON and re-measure the dc power supply current of the flash adaptor. The difference between the currents in (1) and (2) should be between 190 to 220mA. When WLAN is ON, the

firmware has been downloaded and the WLAN module is in the receive state. When OFF WLAN is powered down.

TX tests

Prerequisites

Connect complete phone assembly with C-cover to a PC with Phoenix service software using a USB data cable. From the testing toolbar select WLAN Tx Test option shown below. This test can be used to verify TX

configuration and functionality. The default settings are sufficient for testing the TX operation, although other channels and data rates are equally suitable. To start the test, select the Start option button:

1 Monitor the WLAN TX spectrum on a Spectrum analyser. (When making a radiated test ensure that other

WLAN devices are not transmitting as these may be detected as well, confusing the result). A typical 11MBPS TX spectrum is shown in figure below.

2 To finish the test select the Finish option button. The difference between the two readings should be approximately 150mA and measures the transmit current

in 11MBPS, 802.11b mode of operation.
