RM-244 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.

RM-244 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.

PAGE 106
RM-244 RF troubleshooting The main RX troubleshooting measurement is RSSI reading. This test measures the signal strength of the received signal. For GSM RSSI measurements, see GSM RX chain activation for manual measurements / GSM RSSI measurement (page 4–8). For a similar test in WCDMA mode, see WCDMA RSSI measurement (page 4–10).
PAGE 107
RM-244 RF troubleshooting Note: The phone has two WCDMA bands. The testing and tuning procedures are same for both bands. Just select band I or V. Steps 1. Via Phoenix Testing menu, choose WCDMA/RX Control. 2. In the RX control window, make the following settings: 3. Click Start to activate the settings. If the settings are changed later on (for example, change of channel) you have to click Stop and Start again. Note: Clicking Stop also disables TX control if it was active. 4.
PAGE 108
RM-244 RF troubleshooting WCDMA RSSI measurement Prerequisites WCDMA RX must be activated before RSSI can be measured. For instructions, please refer to WCDMA RX chain activation (page 4–8). Steps 1.

RM-244 RF troubleshooting Figure 26 WCDMA power window RF tunings Introduction to RF tunings Important: Only perform RF tunings if: • one or more of the RF components have been replaced • flash memory chip is replaced or corrupted. RF calibration is always performed with the help of a product-specific module jig, never with an RF coupler. Using an RF coupler in the calibration phase will cause a complete mistuning of the RF part. Important: After RF component replacements, always use autotuning.

RM-244 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.
PAGE 142
RM-244 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.
PAGE 143
RM-244 Camera Module Troubleshooting Figure 33 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 usually cannot be avoided. 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.
PAGE 144
RM-244 Camera Module Troubleshooting Figure 35 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.
PAGE 145
RM-244 Camera Module Troubleshooting Figure 37 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.

RM-244 Camera Module Troubleshooting 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 the 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.

RM-244 System Module and User Interface Clocking scheme In BB5, two main clocks are provided to the system: 38.4MHz RF clock produced by VCTCXO in RF section and 32.768kHz sleep clock produced by AVILMA with an external crystal. 32 k Sleep Clock is always powered on after startup. Sleep clock is used by RAPIDO for low-power operation. SMPS Clk is 2.4 MHz clock line from RAPIDO to BETTY. In deep sleep mode, when VCTCXO is off, this signal is set to '0'-state. BT Clk is 38.

RM-244 System Module and User Interface Figure 52 Bluetooth interface The Bluetooth has a separate built in antenna and is powered by VBAT and the regulated voltage VIO. For audio applications the Bluetooth has a PCM data bus. In addition a UART (universal asynchronous receiver/ transmitter) is used for data communication and controls. WLAN A Wireless Local Area Network (WLAN) is a flexible data communication system in which a mobile user can connect to a local area network through a wireless connection.
PAGE 165
RM-244 System Module and User Interface WLAN ASIC is powered by VBAT. VIO is required for SPI which connects WLAN ASIC to host processor. WLAN requires 38.4 MHz reference clock which is taken from RF VCTCXO via BT/WLAN clock buffer. WLAN shares the same antenna with BT and common RF path is shared according to the coexistence signaling between the ASICs. FM radio Figure 53 FM radio The FM radio is an integrated circuit, controlled by MCU software through a serial bus interface.

RM-244 System Module and User Interface USB USB (Universal Serial Bus) provides a wired connectivity between a PC and peripheral devices. It is a differential serial bus. USB 2.0 is supported with full speed (12 Mbps). Hot swap is supported, which means that USB devices may be plugged in/out at any time. This phone is provided with a specific connector for mini USB. lrda interface IrDA specifies a low-cost, reliable, fully digital peer-to-peer data link between IrDA units at data rates to 115.2k bits/s.

RM-244 System Module and User Interface Figure 54 Interconnections between RAPIDO, EM ASICs, and IR module CBUS interface CBUS is a "main" system control bus in BB5. RAPIDO controls the functionality of EM ASIC (N2200) and EM ASIC (N2300) ASICs with CBUS. CBUS is a four-wire half-duplex master-slave interface. In BB5 CBUS clock frequency is 2.4 MHz. FBUS USB and FBUS have multiplexed interface between EM ASIC (2300) and RAPIDO.
PAGE 168
RM-244 System Module and User Interface The EM ASIC handles the detection of the SIM card. The detection method is based in the BSI line. Because of the location of the SIM card, removing the battery causes a quick power down of the SIM IF. The EM ASIC SIM1 interface supports both 1.8 V and 3.0 V SIM cards. The SIM interface voltage is first 1.8 V when the SIM card is inserted, and if the card does not response to the ATR a 3 V interface voltage is used.

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).
PAGE 181
RM-244 System Module and User Interface 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 bandwidth of the system in use (eg. GSM900). The transmitter functions are implemented in the RF ASIC. Even though the GSM and WCDMA signals pass different components, the principles of the transmission is the same.
