RM-429 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-429 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.

RM-429 RF troubleshooting Receiver troubleshooting Introduction to receiver (RX) troubleshooting RX can be tested by making a phone call or in local mode. For the local mode testing, use Phoenix service software. 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 4–11).
PAGE 113
RM-429 RF troubleshooting Transmitter troubleshooting Introduction to transmitter (TX) troubleshooting Please note the following before performing transmitter tests: • TX troubleshooting requires TX operation. • Do not transmit on frequencies that are in use! • The transmitter can be controlled in local mode for diagnostic purposes. • The most useful Phoenix tool for GSM transmitter testing is “RF Controls”.
PAGE 114
RM-429 RF troubleshooting 3. Check the basic TX parameters (i.e. power, phase error, modulation and switching spectrum), using a communication amalyser (for example CMU200). Note: Frequency error is common as there is no automatic AFC control. It can be adjusted using the AFC input box. Page 4 –14 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.

RM-429 System Module Introduction Phone description RAP3GS is the main digital baseband ASIC in the phone. It contains functionality for GSM EDGE. Camera hardware accelerator is used as a co-processor. N2200 (AVILMA) is mainly the audio ASIC in the phone and N2300 (BETTY) is basically the energy management controller for the phone. Bluetooth is physically integrated in one single ASIC.
PAGE 125
RM-429 System Module Energy management Battery interface The phone is powered by a 3-pole BL-5C S-pack 1020 mAh battery. The three poles are named VBAT, BSI and GND where the BSI line is used to recognize the battery capacity. This is done by means of an internal battery pull down resistor. Figure 15 Battery pin order The battery temperature is estimated by measuring separate battery temperature NTC via the BTEMP line.
PAGE 126
RM-429 System Module Normal and extreme voltages Energy management is mainly carried out in the two Application Specific Integrated Circuits (ASICs) N2300 BETTY and N2200 AVILMA. These two circuits contains a number of regulators. In addition there are some external regulators too. In the table below normal and extreme voltages are shown when a BL-5C battery is used. Table 10 Nominal voltages Voltage Voltage [V] Condition General Conditions Nominal voltage 3.700 Lower extreme voltage 3.
PAGE 127
RM-429 System Module Mode Description RESET RESET mode is a synonym for start-up sequence. RESET mode uses 32 kHz clock to count the REST mode delay (typically 16ms). SLEEP SLEEP mode is entered only from PWR_ON mode with the aid of SW when the system’s activity is low. FLASHING FLASHING mode is for SW downloading. Clocking scheme In BB5.0, two main clocks are provided to the system: 38.4MHz RF clock produced by VCTCXO in RF section and 32.

RM-429 System Module SIM interface The device has one SIM (Subscriber Identification Module) interface. It is only accessible if battery is removed. The SIM interface consists of an internal interface between RAP and EM ASIC (N2200), and of an external interface between N2200 and SIM contacts. The SIM IF is shown in the following figure: Figure 18 SIM interface The EM ASIC handles the detection of the SIM card. The detection method is based in the BSI line.

RM-429 System Module µSD card interface The µSD card is connected to the engine by an external level shifter. Supplied voltages: • VSD: 2.85 V (from level shifter) • VIO: 1.8 V (from AVILMA) Camera The main camera uses a 1.3 megapixel camera module. It has a dedicated capture key. User interface Display module This phone has two displays; one main display and one small display. It does not require any tuning in service.

RM-429 System Module Figure 21 Backlight and illumination block diagram Fold switch The detection of the position of the fold is made through a Hall sensor and an IHF magnet. The magnet is positioned on the top board. When the fold is opened, the applied magnetic field is high. This is sensed by an internal switch, also connected to GND. When the fold is closed, the Hall sensor is fluxed by magnetic field.

RM-429 System Module Figure 23 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. RF description 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.
