RM-443 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-443 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-443 RF Troubleshooting • 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”. • Remember that re-tuning is not a fix! Phones are tuned correctly in production. Note: Never activate the GSM transmitter without a proper antenna load.

RM-443 RF Troubleshooting Figure 23 Typical readings 4. Change the power level (RF controls) and make sure the power reading follows accordingly. Next actions You can troubleshoot the GSM transmitter for each GSM band separately, one band at a time. If you want to troubleshoot GSM1800 or GSM1900, change the band with the RF controls and set the communication analyser accordingly.

RM-443 System Module and User Interface Introduction Phone description RAP is the main digital baseband ASIC in the phone. It contains functionality for the GSM EDGE. The hardware accelerator is used as a camera accelerator. N2200 (AVILMA) is mainly the audio ASIC in the phone and N2300 (BETTY) is basically the energy management controller for the phone.
PAGE 127
RM-443 System Module and User Interface Energy management Battery and charging BL-5CT battery The phone is powered by a 3-pole BL-5CT 1050 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 28 Battery pin order The battery temperature is estimated by measuring separate battery temperature NTC via the BTEMP line.
PAGE 128
RM-443 System Module and User Interface Figure 30 Small (right) and wide (left) charger plugs The phone can also be charged through the micro USB interface. Charging is controlled by energy management, and external components are needed to protect the baseband module against EMC, reverse polarity and transient frequency deviation. Charging a dead battery Charging of a dead battery has to be carried out via an approved NOKIA charger.

RM-443 System Module and User Interface Power key and system power-up When the battery is placed in the phone the power key circuits are energized. When the power key is pressed, the system boots up (if an adequate battery voltage is present). Power down can be initiated by pressing the power key again (the system is powered down with the aid of SW). The power key is connected to EM ASIC N2200 (AVILMA) via PWRONX signal.
PAGE 130
RM-443 System Module and User Interface Figure 31 SIM interface The EM ASIC AVILMA 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 interface. The SIM 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.
PAGE 131
RM-443 System Module and User Interface Charger interface The charger interface is a 2mm Dynamo charger plug. Older chargers with a 3.5mm plug are supported via the charger adapter cable CA-44. Charging is controlled by BETTY. Additional external components are needed for EMC purposes, reverse polarity and transient protection of the input to the baseband module.

RM-443 System Module and User Interface Bluetooth The Bluetooth module provides a fully digital link for communication between a master unit (the phone) and one or more slave units (e.g. a wireless headset). Data and control interface for a low power RF module is provided by the module. The Bluetooth is physically integrated with the FM radio into one discrete module (BTHFMRDS2.2D / N6000). Figure 35 Bluetooth interface The Bluetooth antenna has been integrated into the main antenna module assembly.
PAGE 133
RM-443 System Module and User Interface The FM radio is an integrated circuit, controlled by MCU software via the I2C bus. The wires of the headset are used as elements of the antenna, and no other antenna is needed for FM radio reception. The radio has an automatic band search function, which can search for a strong station. Camera concept Camera characteristics The device has an integrated high resolution 3.2 Megapixel auto focus digital camera supporting still image and video capture.

RM-443 System Module and User Interface Signals with different frequencies take different paths, therefore being handled by different components. Transmitter (TX) The digital baseband signal (e.g. 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 (e.g. GSM900). The transmitter functions are implemented in the RF ASIC.
