Page iii RM-333; RM-334; RM-335 Warnings and cautions 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. Page iv COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 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 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page v RM-333; RM-334; RM-335 Care and maintenance 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. Page vi COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.

All rights reserved. Page vii RM-333; RM-334; RM-335 Battery information 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. Page viii COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.

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 2 kHz. 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 Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia.

When combined, the component responds to illuminance similar as human eye. • Vdd Filtering capacitor C1103 Ambient Light Sensor information is used to control keypad and display brightness of the phone. Keyboard backlight is turned OFF, when it’s not needed. 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 –46 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 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 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 3 –47 RM-333; RM-334; RM-335 BB Troubleshooting 4. Choose Tuning -> Ambient Light Sensor Calibration. You should see the following window: 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: Coefficient = 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.

The result column will change to Passed after a few seconds if operating properly. Page 3 –60 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 BB Troubleshooting 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. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 3 –61 RM-333; RM-334; RM-335 BB Troubleshooting 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. Page 3 –62 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 BB Troubleshooting 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. RX Tests Prerequisites Connect complete phone assembly with C-cover to a PC with Phoenix service software using a USB data cable. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 3 –63 RM-333; RM-334; RM-335 BB Troubleshooting There are different options available for testing the Rx path. The simplest is to use the WLAN to report Rx packets when operating in an area where there is an active WLAN network. Simply starting an Rx test will show the number of packets detected by the WLAN module as it monitors the network. However, it does require a properly configured WLAN network. From the testing toolbar select WLAN Rx Test option shown below. This test can be used to verify Rx configuration and functionality. To start the test, select the Start option button. As the WLAN monitors an active WLAN network, the Rx test results window will update and show the number of Frames received, as well as the Packer error rate. Monitoring the detected frames is a simple method to verify the WLAN antenna and receiver path is working properly. WLAN auto tuning In case of WLAN ASIC change, RF power auto tuning is needed. Connect WLAN RF test connector to CMU200 input using proper RF cable. Start Phoenix WLAN autotune window. Check the settings and verify your PC communicates with CMU200 via GPIB.

Issue 2 RM-333; RM-334; RM-335 RF Troubleshooting 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). 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 (it is only 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 communication Test Set Screen dumps are from CMU200. Other testers are different. 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 verify functionality of the cellular RF block without removing RF shield. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.

Issue 2 RM-333; RM-334; RM-335 RF Troubleshooting Auto tuning Introduction to RF tunings RF tuning is always performed with the help of a product-specific module jig, never with an RF coupler. Using an RF coupler in the tuning phase will cause a complete mistuning of the RF part. Cable and adapter losses RF cables and adapters have some losses. They have to be taken into account when the phone is tuned. As all RF losses are frequency dependent, the user has to act very carefully and understand the measurement setup. For RF attenuations of the module jig and RF cable, please refer to the Service Tools section. Auto tuning This phone can be tuned automatically. Auto tuning is designed to align the phone's RF part easier and faster. It performs calibrations, tunings and measurements of RX and TX. The results are displayed and logged in a result file, if initiated. Hardware set up For hardware requirements for auto tuning, please refer to Service concept for RF testing and RF/BB tuning (page 4–22). Phoenix preparations Install the phone specific data package, for example Nokia_firmware_RM-333_EUROPE_10.014_v41.0.exe. This defines phone specific settings. Auto tuning procedure 1 Make sure the phone (in the jig) is connected to the equipment. Otherwise some menus will not be shown in Phoenix. 2 To go to autotune, select Tuning (Alt-U)→Auto-Tune (Alt-A) from the menu. 3 Start autotuning by clicking the Tune button.

Issue 2 RM-333; RM-334; RM-335 Camera Module Troubleshooting Introduction to camera module troubleshooting Background, tools and terminology Faults or complaints in camera operation can be roughly categorised into three subgroups: 1 Camera is not functional at all; no image can be taken. 2 Images can be taken but there is nothing recognizable in them. 3 Images can be taken and they are recognizable but for some reason the quality of images is seriously degraded, or customer complains about image quality. Image quality is very hard to measure quantitatively, and even comparative measurements are difficult (comparing two images) to do, if the difference is small. Especially if the user is not satisfied with his/her device's image quality, and tells, for example, that the images are not sharp, it is fairly difficult to accurately test the device and get an exact figure which would tell whether the device is functioning properly. Often subjective evaluation has to be used for finding out if a certain property of the camera is acceptable or not. Some training or experience of a correctly operating reference device may be needed in order to detect what actually is wrong, or is there anything wrong at all. It is easy for the user to take bad images in bad conditions. Therefore the camera operation has to be checked always in constant conditions (lighting, temperature) or by using a second, known-to-be good device as reference. Experience helps significantly in analysing image quality. Terms Autofocus Camera module contains lens movement mechanics for focus adjustment. Autofocus enables camera to take sharp images of objects positioned between 10cm to infinity. During AF the viewfinder image will be momentarily blurred as the camera searches for the right focus setting. Digital zoom Digital zoom is done by first cropping the image by the zoom ratio and then upscaling it to the output resolution. This will decrease the image quality especially with high zoom ratios. Dynamic range Camera's ability to capture details in dark and bright areas of the scene simultaneously. Exposure time Camera modules use silicon sensor to collect light and for forming an image. The imaging process roughly corresponds to traditional film photography, in which exposure time means the time during which the film is exposed to light coming through optics. Increasing the time will allow for more light hitting the film and thus results in brighter image. The operation principle is exactly the same with silicon sensor, but the shutter functionality is handled electronically i.e. there is no mechanical moving parts like in film cameras. Flicker Phenomenon, which is caused by pulsating in scene lighting, typically appearing as wide horizontal stripes in an image. ND-filter Neutral density filter is a filter which is used in very bright conditions to reduce the amount of light hitting the sensor. The filter is built into the camera module and applied automatically when needed. Noise Variation of response between pixels with same level of input illumination. Resolution Usually the amount of pixels in the camera sensor. In some occasions the term resolution is used for describing the sharpness of the images. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 5 –5 RM-333; RM-334; RM-335 Camera Module Troubleshooting Sensitivity Camera module's sensitivity to light. In equivalent illumination conditions, a less sensitive camera needs a longer exposure time to gather enough light in forming a good image. Analogous to ISO speed in photographic film. Sharpness Good quality images are 'sharp' or 'crisp', meaning that image details are well visible in the picture. However, certain issues, such as non-idealities in optics, cause image blurring, making objects in picture to appear 'soft'. Each camera type typically has its own level of performance. Shutter The electronic shutter is used when short exposure times are needed and in video. When the mechanical shutter is used a black sheet will cover the lens after the exposure. The effect of image taking conditions on image quality There are some factors, which may cause poor image quality, if not taken into account by the end user when shooting images, and thus may result in complaints. The items listed are normal to camera operation and are not a reason for changing the camera module. Autofocus When the camera is focusing a lens is moved inside the module to give the sharpest possible image. This camera module is specified to operate satisfactorily from 10 cm to infinite distance of scene objects. Trying to photograph objects closer than 10 cm is likely to result in a blurred out of focus image. The lack of sharpness is first visible in full resolution images. Images taken very close to the subject, a limited depth of focus will be visible, that is the upper or lower parts of the image may be out of focus. This is normal; do not change the camera module. Figure 36 Only center part of image is in focus due to limited depth of focus The amount of light available In dim conditions camera runs out of sensitivity. The exposure time is long (especially in the night mode) and the risk of getting shaken (= blurred) images increases. In addition, image noise level grows. The maximum exposure time in the night mode is ¼ seconds. Therefore, images need to be taken with extreme care and by supporting the phone when the amount of light reflected from the target is low. Because of the longer exposure time and larger gain value, noise level increases in low light conditions. Sometimes blurring may even occur in daytime, if the image is taken very carelessly. See the figure below for an example. This is normal; do not change the camera module. Page 5 –6 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 Camera Module Troubleshooting Figure 37 Blurring caused by shaking hands Movement in bright light If an image is taken of moving objects or if the device is used in a moving vehicle, object 'skewing' or 'tilting' may occur. This phenomenon is fundamental to most CMOS camera types, and may happen when using the electronic shutter. The movement of camera or object sometimes cause blurring indoors or in dim lighting conditions because of long exposure time. This is normal; do not change the camera module. Figure 38 Near objects get skewed when taking images from a moving vehicle Temperature High temperatures inside the mobile phone cause more noise to appear in images. For example, in +70 degrees (Celsius), the noise level may be very high, and it further grows if the conditions are dim. If the phone processor has been heavily loaded for a long time before taking an image, the phone might have considerably higher temperature inside than in the surrounding environment. This is also normal to camera operation; do not change the camera module. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 5 –7 RM-333; RM-334; RM-335 Camera Module Troubleshooting Figure 39 Noisy image taken in +70 degrees Celsius Phone display If the display contrast is set too dark, the image quality degrades: the images may be very dark depending on the setting. If the display contrast is set too bright, image contrast appears bad and "faint". This problem is solved by setting the display contrast correctly. This is normal behaviour; do not change the camera module. Basic rules of photography (especially shooting against light) Because of dynamic range limitations, taking images against bright light might cause either saturated image or the actual target appear too dark. In practice, this means that when taking an image indoors and having, for example, a window behind the object, the result is usually poor. This is normal behaviour; do not change the camera module. Figure 40 Image taken against light Flicker In some occasions a bright fluorescent light may cause flicker in the viewfinder and captured image. This phenomenon may also be a result, if images are taken indoors under the mismatch of 50/60 Hz electricity network frequency. The electricity frequency used is automatically detected by the camera module. In some very few countries, both 50 and 60 Hz networks are present and thus probability for the phenomenon increases. Flickering occurs also under high artificial illumination level. Flickering only occurs when the rolling shutter is used. This is normal behaviour; do not change the camera module. Page 5 –8 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 Camera Module Troubleshooting Figure 41 Flicker in an image; object illuminated by strong fluorescent light Bright light outside of image view Especially the sun can cause clearly visible lens glare phenomenon and poor contrast in images. This happens because of undesired reflections inside the camera optics. Generally this kind of reflections are common in all optical systems. This is normal behaviour; do not change the camera module. Figure 42 A lens reflection effect caused by sunshine Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 5 –9 RM-333; RM-334; RM-335 Camera Module Troubleshooting Examples of good quality images Figure 43 Good image taken indoors Figure 44 Good image taken outdoors Image quality analysis Possible faults in image quality 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 may be expected to appear: • Dust (black spots) • Lack of sharpness • Bit errors In addition, there are many other kinds of possibilities for bad image quality, but those are ruled out from the scope of this document since the probability of their appearance is small. Page 5 –10 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 Camera Module Troubleshooting Testing for dust in camera module Symptoms and diagnosis For detecting these kinds of problems, take an image of a uniform white surface and analyse it in full resolution. A good quality PC monitor is preferred for analysis. Search carefully, since finding these defects is not always easy. Figure "Effects of dust on optical path" is an example image containing easily detectable dust problems. When taking a white image, use uniformly lightened white paper or white wall. One possibility is to use uniform light but in this case make sure that the camera image is not flickering when taking the test image. In case flickering happens, try to reduce illumination level. Use JPEG image format for analysing, and set the image quality parameter to ‘High Quality’. Black spots in an image are caused by dirt particles trapped inside the optical system. Clearly visible and sharp edged black dots in an image are typically dust particles on the image sensor. These spots are searched for in the manufacturing phase, but it is possible that the camera body cavity contains a particle, which may move onto the image sensor active surface, for example, when the phone is dropped. Thus it is also possible that the problem will disappear before the phone is brought to service. The camera should be replaced if the problem is present when the service technician analyses the phone. If a dust particle is lying on the infrared filter surface on either side, they are hard to locate because they are out of focus, and appear in the image as large, grayish and fading-edge 'blobs'. Sometimes they are invisible to the eye, and thus the user probably does not notice them at all. However, it is possible that a larger particle disturbs the user, causing need for service. Figure 45 Effects of dust on optical path If large dust particles get trapped on top of the lens surface in the cavity between camera window and lens, they will cause image blurring and poor contrast. The dust gasket between the window and lens should prevent any particles from getting into the cavity after the manufacturing phase. If dust particles are found on the sensor, this is classified as a manufacturing error of the module and the camera should be replaced. Any particles inside the cavity between the protection window and lens have most probably been trapped there in the assembly phase at a Nokia factory. Unauthorized disassembling of the product can also be the root of the problem. However, in most cases it should be possible to remove the particle(s) by using clean compressed air. Never wipe the lens surface before trying compressed air; the possibility of damaging the lens is substantial. Always check the image sharpness after removing dust. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 5 –11 RM-333; RM-334; RM-335 Camera Module Troubleshooting Testing camera image sharpness Symptoms and diagnosis If pictures taken with a device are claimed to be blurry, there are five possible sources for the problem: 1 The protection window is fingerprinted, soiled, dirty, visibly scratched or broken. 2 The camera module has failed to focus correctly, producing a blurred image. 3 User has tried to take pictures in too dark conditions and images are blurred due to handshake or movement. This is not a cause to replace camera module. 4 There is dirt between the protection window and the camera lens. 5 The protection window is defective. This can be either a manufacturing failure or caused by the user. The window should be changed. A quantitative analysis of sharpness is very difficult to conduct in any other environment than optics laboratory. Therefore, subjective analysis should be used. If no visible defects (items 1-4) are found, a couple of test images should be taken. Generally, a wellilluminated typical indoor scene, such as the one in Figure "Good image taken indoors", can be used as a target. The main considerations are: • The camera module has to be given time to focus correctly. Correct focusing is normally indicated with a flashing icon or green bracket in the viewfinder. During focusing, the image in the viewfinder moves slightly back and fourth, this is normal and shows that the lens unit is moving. During the movement a faint sound can be heard from the camera head. • The protection window has to be clean. • The amount of light (300 – 600 lux (bright office lighting)) is sufficient. • The scene should contain, for example, small objects for checking sharpness. Their distance should be 1 – 2 meters. • If possible, compare the image to another image of the same scene, taken with a different device. Note that the reference device has to be a similar Nokia phone. There are several conditions in which AF operation is challenging for the camera module, i.e. failing from time to time. These include: • Low light scenes and night mode • Scenes with low contrast • Fast-moving objects AF operation is disabled on purpose in “night”, “landscape”, “sports”, and “video” modes. When using these modes the lens is set to a predetermined focal position and isn’t moved during use. Under low light and night mode the AF function is slower than under good light, it may even fail to find correct focus position. Low contrast scenes or fast moving objects may also slow down or cause AF to fail. This is normal operation, and is not a cause to replace camera. The operation of AF can be tested by taking images of objects at different distances. Good distances are 20 cm, 60 cm and infinity (>3 m). Any LED or xenon flashes should not be used while taking the images. The taken images should be analysed on PC screen at 100% scaling simultaneously with a reference image. Pay attention to the computer display settings; at least 65000 colors (16 bit) have to be used. 256 (8-bit) color setting is not sufficient; true color (24 bit, 16 million colors) or 32 bit (full color) setting is recommended. If the differences are noticeable at a glance and also if the one under investigation is significantly inferior, the module might have a faulty lens. In this case, the module should be changed. Always recheck the resolution after changing the camera module. If a different module produces a clearly noticeable quality gap, Page 5 –12 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 Camera Module Troubleshooting the fault is probably in the camera window. Check the window by looking carefully through it when replacing the module. As references Figure "Good image taken indoors" and Figure "Good image taken outdoors" can be used. Another possibility is to use a service point comparison phone, if available. Effects of dirty or defective camera lens protection window The following series of images demonstrates the effects of fingerprints on the camera protection window. Note: The effects of any dirt in images can vary very much; it may be difficult to judge if the window has been dirty when some image has been taken or if something else has been wrong. That is why the cleanness of the protection window should always be checked and the window should be wiped clean with a suitable cloth. Figure 46 Image taken with clear protection window Figure 47 Image taken with greasy protection window Bright point light sources might cause images that have flares around the light source if the protection window is dirty. A smeared fingerprint may be hard to see on the protective window but if will affect the image quality. These flares can be avoided by cleaning the window with a suitable cloth.

Page 5 –13 RM-333; RM-334; RM-335 Camera Module Troubleshooting Figure 48 Image of point light sources taken with a clean protective window Figure 49 Image of point light sources taken with a dirty (finger print) protective window Faulty pixels in images Faulty pixels are pixels that do not respond to light in the same way as the pixels around them. There are three main types of faulty pixels, dead, stuck and hot pixels. Dead pixels are always black or significantly darker than their surrounding. Dead pixels appear as black spots in all lightning conditions. Camera modules producing images with dead pixels that are clearly noticeable should be replaced. If the pixel remains always saturated to its maximum value it is stuck. Stuck pixels may appear as red, green, blue or white spots in all lightning conditions. Camera modules producing images with one or more stuck pixels should be replaced. Hot pixels are pixels that easily saturate in dim light conditions. It is normal to get a lot of noise and hot pixels in night conditions or otherwise dark conditions. The hot pixels should disappear when the ambient light is increased, but may still appear in darker areas of an otherwise well illuminated scene. When examining an image for defect pixels, test images should be viewed as 100% enlargements on a PC monitor. Page 5 –14 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 Camera Module Troubleshooting Figure 50 Enlargement of a hot pixel Flash photography problems Use of flash device may affect the image in many ways. • White balance errors. The image may get a wrong tone due to mixing of flash colour temperature and ambient lightning. This is unwanted but normal feature. • Dust reflections. Dust or water drops in front of the flash unit may reflect strongly to the camera sensor. See the following figure.

This device has some state of the art features which have been utilised in the Nokia implementation. Apart from having excellent RF transmitter performance and exceptional AF performance the device offers a number of unique features, including the ability to retune the output stage of the device to ensure optimal matching between the Tx antenna and the output stage of the device. Functional description The FMTx 2.1 solution comprises of the Si4713 device and ten external components. These components consist of: • A filter - an inductor and a varistor for filtering of emissions from the chip • ESD protection - a resistor and diode package • A dual capacitor package which is connected to the analogue audio input pins LIN & RIN. The fundamental purpose of these capacitors is as DC blocking caps • A filter on the reset line comprising a capacitor and a resistor • An antenna which also provides the inductive load required by the Si4713 device The Si4713 device is in a 3 x 3mm 20 pin QFN package. Current implementations make use of the DAC33 device which allows data to be digitally clocked into the DAC at high data rates, buffered and then streamed out at the correct rate while the rest of the baseband is put to sleep in order to save power. This solution significantly increases playback time of audio content. The Si4713 device has the following features: • 88.1MHz – 107.9MHz FM band support. • Programmable pre-emphasis (50/75us). • Analogue audio interface • Audio silence/signal present detection. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 6 –5 RM-333; RM-334; RM-335 FMTx 2.1 Technical Description • Programmable reference clock. • RDS/RBDS encoder • Loop and monopole antenna support with self-calibrated capacitor tuning. • Programmable transmit level. • Audio dynamic range control. System block diagram Figure 52 FMTx 2.1 system block diagram The figure above shows the basic system block diagram for the FMTx 2.1 implementation. _SEN is shown here unconnected since this pin decides which I2C address is used depending on if this pin is pulled low or high. On RM-333 the _SEN is pulled high by connecting it to VIO. RM-333 uses a loop antenna which is located in the removable C-cover of the device. The loop antenna also acts as the tuning inductor which is required by the Si4713 chip. The location of the antenna in the removable cover means that ESD protection is required to prevent damage to the Si4713 device. Page 6 –6 COMPANY CONFIDENTIAL Copyright © 2008 Nokia.

Issue 2 RM-333; RM-334; RM-335 FMTx 2.1 Troubleshooting FMTx 2.1 schematic Figure 53 FMTx 2.1 schematic The handset uses an antenna that is integral to the removable cover. The connection to the cover is exposed when the cover is removed. The loop antenna requires two connection points, J6200 and J6201 (the signal and the ground). It is important to check these connection points for damage or dirt since the performance of the FMTx 2.1 implementation will be severely impaired if these connections are not in good condition. FMTx 2.1 component layout Figure 54 FMTx 2.1 Component References and Location The main component of the FMTx 2.1 solution is the Si4713 low power transmitter device (N6150). Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 7 –5 RM-333; RM-334; RM-335 FMTx 2.1 Troubleshooting FMTx 2.1 PWB traces Figure 55 FMTx 2.1 layout Specific digital and power supply test points Using access to signals figure as a reference it can be seen that supplies to the Si4713 device VIO (pin 10) and VDD (pin 11) can be accessed easily. The FMTx 2.1 solution utilises a QFN package. This type of package lends itself well to analysis of signals on the various pins of the device. VIO & VDD VIO should be in the range 1.5 to 3.6 Volts. VDD should be in the range 2.7 to 5.5 Volts. _RST Also, the _RST signal to the device can be monitored. This is an active low signal and should only be asserted during power up. The _RST signal is driven by the PURX line. The state of pins 19 & 18 (GPO1 and GP02 respectively) on the rising edge of the _RST pin determines what interface is selected when the device powers up. Table 6 Bus mode selection truth table Bus Name Bus Mode GPO1 GPO2/IRQ I2C 2-Wire High Low SPI SPI High Low (must drive) CBus 3-Wire Low (must drive) Low It’s possible that if GP01 and/or GPO2 are not at the correct state when the Si4713 device has power applied then the wrong bus mode could be selected and the handset would be unable to communicate with the device. For RM-333, the bus mode should be I2C. Page 7 –6 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 FMTx 2.1 Troubleshooting _SEN The _SEN pin is used to select one of two possible 7-bit I2C bus addresses. When _SEN is low, the I2C bus address for the Si4713 device is 0010001 (0x11). When _SEN is high, the I2C bus address for the Si4713 is 1100011 (0x63). If the _SEN signal is not correct (i.e. not selecting the correct I2C address), then this is also another possible reason why control of the FMTx 2.1 feature might not be possible. For RM-333 the I2C address used for FMTx 2.1 will be 0x63. Table 7 I2C 7-bit bus address selection summary I2C address _SEN 0010001 (0x11). High 1100011 (0x63). Low FMTx2.1 specific RF test points TXO Pin 4 is the TXO pin. This is the transmitter output pin and probe access can be obtained easily. Using a high impedance probe and a spectrum analyser it would be possible to examine the TXO pin and check that the transmitter is outputting a signal. Specific clock test points RCLK Pin 9 is the RCLK (Reference Clock) input to the device. This is typically 32.768KHz and is driven from the sleep clock from the base band. When measuring this clock frequency, it may be seen to vary by as much as +/120 ~ 200ppm. The device can only typically tolerate +/- 20ppm in order to maintain transmit frequency accuracy. To overcome this, the software driver for the device calculates what the actual sleep clock (RCLK) frequency is and periodically programs the device with this frequency. The device then internally adjusts its dividers in order to maintain the required output frequency. Using this method it is possible to reduce the effective ppm of the reference clock down to +/- 14ppm over the full operating temperature range of -15 to +50 degrees Centigrade. General visual inspection guidelines • If the handset has the FMTx antenna in the back cover then check the condition of the cover, the antenna trace and any mechanical interfaces for the antenna e.g. pogo pins. • Check that the Si4713 device is placed correctly on the PWB and that there are no obvious signs of damage. • Check the surrounding components and ensure correct placement on the PWB and that there is no visual damage. Check that there are no missing components. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.

Issue 2 RM-333; RM-334; RM-335 FMTx 2.1 Troubleshooting FMTx2.1 Si4713 visual inspection troubleshooting Troubleshooting flow Checking validity of signals Please refer to Access to signals figure as a reference. Generally all power supply levels and clocks willbe consistent. Signals on the analogue audio input pins (RIN & LIN – pins 15 and 16 respectively) will be dependant on the audio content being injected to the device. During the audio self test (initiated from Phoenix) it is possible to monitor these pins and check that the DSP generated 1KHz tones can be seen at some point during the test. Check that the signals are clean and that no obvious distortion can be seen such Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 7 –11 RM-333; RM-334; RM-335 FMTx 2.1 Troubleshooting as clipping of the signals. Typical maximum swing of these tones will be ~636mV peak to peak. The maximum swing may vary between Nokia handsets but for the FMTx 2.1 implementation, the swing should not be greater than the aforementioned value. FMTx2.1 troubleshooting faults Possible faults Expected fault reports relating to the FMTx 2.1 implementation may consist of one or more of the following; 1 No left audio 2 No right audio 3 No audio 4 Can’t start FMTx 5 Can’t locate FM transmission on an FM receiver or no FM transmission 6 Distortion on audio 7 Poor reception on FM receiver 8 No RDS information Initial fault analysis Where possible, attempt to reproduce and verify the reported fault. Intermittent problems are likely to be due to bad connections or broken components/solder joints. Any faults relating to poor FM transmitter performance or frequent failure to locate usable frequencies when performing a scan are likely to be due to some kind of antenna issues. In handsets that utilise an antenna solution in a removable cover it is likely that the connecting interface pins are either damaged, dirty or that the cover fits poorly perhaps due to broken tabs/latching lugs. Poor audio fault reports may also be due to the above antenna issues. Phoenix PC tool Setting Up Phoenix Required equipment: • A Deskey security dongle for Phoenix to run. • The latest version of Phoenix that has the FMTx 2.1 GUI installed on a PC (version 2007.21.000.27897 or greater). • A jig suitable for the handset. • A cable to connect the jig/handset to the PC. Run Phoenix and select the FMTx panel. Page 7 –12 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Issue 2 RM-333; RM-334; RM-335 FMTx 2.1 Troubleshooting Using the FMTx panel to drive the FMTx 2.1 features Figure 56 FMTx panel before connection to the handset Figure 57 FMTx panel after connection to the handset Typing in a valid FM transmitter frequency and clicking on ‘Activate’ will turn on the FMTx feature and will begin transmitting the carrier on the selected frequency. Note: Unless this carrier signal is modulated with some audio (either via the music player or a DSP or Si4713 generated tone) then all that will be heard if an Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 7 –13 RM-333; RM-334; RM-335 FMTx 2.1 Troubleshooting FM receiver is tuned to the same frequency would be silence. After approximately 10 seconds of silence the handset should begin to ‘chirp’ periodically with a short 1Khz tone that repeats every 5 seconds. This indicates that there is no audio input and reminds the user that the feature is on. The Phoenix FMTx 2.1 panel can be used to control the following features; • Set the FM frequency to transmit on (88.1 to 107.9MHz). • Select Stereo or Mono mode (generally all Nokia handsets will only use stereo) • Mute both left and right audio channels. • Mute only the left or the right audio channels. • Allow an internal tone to be generated and transmitted from the Si4713 device. The audio frequency of this tone can be selected along with the on/off time and the volume of the tone. Selecting 0 (zero) in either the on or off time will produce a continuous tone. • Obtain a list of suitable ‘quiet or free’ channels. This effectively performs an RSSI (RPS) scan to locate quiet channels to transmit on. If the ‘AutoJump’ tick box is checked then this list will be transmitted to the FM receiver to allow the handset to perform AF jumps. This is dependent on the Nokia handset and if the FM receiver is RDS capable. The use of AF feature allows an RDS capable FM receiver to follow the transmissions of the FM transmitter automatically. • FMTx 2.1 status panel. This provides information on the state of the FMTx feature. This can be polled by Phoenix at regular intervals defined by the user when the ‘Read periodically each...’ check box is checked. The status can otherwise be read at any point by clicking on the ‘Read’ button. The MCC value is the ‘Mobile Country Code’ and provided the phone is registered on a network will provide the code pertaining to the country in which it resides. The antenna tuning value is a good indicator of the state of the antenna and the other components connected to the TXO pin. For RM-333 the tuning values should be in the range 0 – 80. Any value outside of this range will indicate some problem with the components connected to the TXO pin (including the antenna). In the case of a removable antenna, the cause of the out of range value is like to be because of a poor antenna connection. This might be because of broken or dirty connections between the handset and the cover in which the antenna is fitted. • The RDS panel can be used to set the PS name and/or to enter a Radio Text (RT) string. If access to an FM receiver is available that supports RDS then these strings can be observed on the display of the FM receiver. Page 7 –14 COMPANY CONFIDENTIAL Copyright © 2008 Nokia.

Issue 2 RM-333; RM-334; RM-335 FMTx 2.1 Troubleshooting Figure 58 FMTx panel in action Using the audio self test The audio self test can be used to quickly determine if the left and right audio paths are intact. The left and right audio connectivity self test process performs the following steps: 1 Measure and store silence. 2 Inject 1KHz tone (left or right) to give 75KHz deviation. Measure and store. 3 Inject same tone on both left and right analogue audio inputs. Measure and store. Compare result from (2) with result from (1). If the delta is NOT more than a specified threshold level then fail. This would indicate that the selected channel is open circuit. If an over deviation indication is detected on (2), then the audio channels must be shorted together. This is a fail condition. For (3), a returned value of zero is expected. This indicates that there is an over deviation condition which in turn indicates that the ‘other’ audio input channel is connected correctly. If on (3) there is no over deviation response, then the ‘other’ channel must be open circuit at some point in the audio path. This is a fail condition. The table shows the truth table for the left and right audio self test.

All rights reserved. Issue 2 RM-333; RM-334; RM-335 System Module and User Interface Bluetooth and FM RDS radio module Bluetooth and FM radio receiver are provided by the same ASIC (Broadcom BCM2048). The device supports Bluetooth operation and FM radio rececption in both European/USA and Japanese bands (the appropriate region-specific FM radio band is pre-configured in the phone software). The UART interface allows the device to communicate with the phone baseband engine using Bluetooth HCI commands. Commands to the FM radio can also be sent over the I2C interface. When Bluetooth is switched on, the phone user interface the BT_RESETX line is toggled to reset the Bluetooth device, and commands are sent over the UART interface to configure the device. If UART communication fails (due to a hardware fault) it will not be possible to switch on Bluetooth from the phone user interface. The device has two clock signals: SYS_CLK (19.2MHz, 26.0MHz, or 38.4MHz supported) and SLEEP_CLK (32.768kHz). The SLEEP_CLK is supplied all the time the phone is switched on. To maximise the phone standby time, it is only necessary to provide a SYS_CLK signal when Bluetooth activity occurs, such as sending Bluetooth data to another device, or checking periodically if there are any other Bluetooth devices attempting to communicate with it. At other times when the Bluetooth device is in standby mode or the FM radio is switched on it is only necessary to provide a SLEEP_CLK signal. The Bluetooth-FM ASIC is powered directly from the phone battery voltage line (VBAT). An internal regulator is enabled when Bluetooth or FM radio is switched on. Bluetooth audio signals are sent to and from the device using a PCM interface. The Bluetooth RF signal is routed via a buried track to the Bluetooth antenna on the side of the PWB. An RF filter is needed between the Bluetooth antenna and Bluetooth ASIC to prevent interference to and from the celluar phone antenna. Phones that have both Bluetooth and WLAN use a shared antenna, as both services occupy the 2.4GHz ISM frequency band. The co-existence signaling interface between Bluetooth and WLAN ASICs controls the RF activity in the shared frequency band. The audio signal from the FM radio is routed via the phone Audio ASIC to the phone headset or loudspeaker. The external wired headset is also used as an Antenna for the FM radio. The FM radio receiver RF signal is routed from the ASIC via a buried track to an impedance matching circuit placed near the headset connector. The following block diagram shows how Bluetooth-FM is connected to the host engine. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.

A block diagram of the UI module is shown below. For clarity, the filtering components are not shown. Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 8 –17 RM-333; RM-334; RM-335 System Module and User Interface Figure 72 User interface block diagram The interface to the UI capacitive sensing controller is at 3.0V, which is provided from the engine by a dedicated linear regulator, and a dedicated level shifter provides the interface to allow the otherwise 1.8V logic levels of the engine to be used on the UI. The capacitive sensors function by sensing changes in the the charge coupled from one electrode to another when the users finger is placed close to the electrodes patterns. There are further mechanical domes associated with this sensing arrangement which only allows the scanning of the charge transfer to occur when the user presses down on the front of the UI module – this is intended to prevent false key-activations. Due to the construction of the module (it is mostly glued together) service is not possible, and if faultly, must be replaced. This includes any faults that are found in the internal microphone or the lower of the two IHF speakers. For operational reasons, the modules are supplied unlocalised, and the correct localization front-panel needs to be attached after the ‘bare’ module has been installed in the handset.

Issue 2 RM-333; RM-334; RM-335 System Module and User Interface Illumination LED driver solution Three LP5521 ‘NJOY LED drivers are used to supply power for different light segments. Each LED driver has three independently programmable constant current outputs (R, G and B). LED drivers are controlled by Rapido via ISA_I2C bus and they use 32kHz external clock from Vilma. Figure 75 Illumination block diagram Light segments 9+1 different light segments are used for illumination, each having 1-4 parallel connected LEDs (see Figure 2). ITU and Game light segments are connected to the same LED driver output. Betty controls them via GenOut1 and GenOut2 outputs (see Figure 1). Parallel connected LEDs which are in same LED driver output branch have serial resistor to even their currents. As ITU keyboard backlights are controlled by the Ambient Light Sensor (ALS) they are turned ON only in dark ambient light. RM-333 has a self-emissive AM OLED display, therefore it does not need LEDs for backlighting Issue 2 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved. Page 8 –21 RM-333; RM-334; RM-335 System Module and User Interface Figure 76 Light segments Naviscroll HW53 uses Quantum QT12C15 as Naviscroll Driver. As shown in Figure 1, it is interfaced to RAPIDO via SPP I2C bus for control and data, two change lines TouchPadInt and KeyInt used by Naviscroll Driver to report to RAPIDO any changes in the touchpad state or changes in the S60 key states, Rst is used as a reset signal from RAPIDO to Naviscroll Driver. On the other side, Naviscroll Driver interfaces Naviscroll touchpad and S60 keys as 3x4 matrix. When there is a change in the touchpad state i.e. when the finger is scrolled over the naviscroll touchpad the Naviscroll Driver gives an interrupt to RAPIDO via TouchPadInt line by pulling it low. Similarly when any of the S60 keys is pressed the Naviscroll Driver gives an interrupt to RAPIDO via KeyInt line by pulling it low. When receiving either of the Interrupts, RAPIDO performs an I2C data read from Naviscroll Driver internal registers to determine Naviscroll touchpad XY position change if TouchPadInt was detected and to determine which S60 keys were pressed if KeyInt was detected. After that, the interrupt lines change state from low to high. 2V8 voltage regulator located on the UI flex supplies power for the Naviscroll driver.

Receiver (RX) An analogue signal is received by the phone's antenna. The signal is converted to a digital signal and is then transferred further to the baseband (eg. to the earpiece). The receiver functions are implemented in the RF ASIC. Signals with different frequencies take different paths, therefore being handled by different components. The principle of GSM and WCDMA is the same. Transmitter (TX) The digital baseband signal (eg. from the microphone) is converted to an analogue signal, which is then amplified and transmitted from the antenna. The frequency of this signal can be tuned to match the bandwith of the system in use (eg. GSM900). The transmitter functions are implemented in the RF ASIC. Even though the GSM and WCDMA signals are sent via different components, the principles of the transmission is the same. Page 8 –32 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.
