RM-364 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-364 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-364 RF troubleshooting Figure 16 General voltage checking test points (main board, top side) 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 108
RM-364 RF troubleshooting Steps 1. Set the phone to local mode. 2. Activate RSSI reading in Phoenix (Testing→GSM→RSSI reading ) Results The reading should reflect the level of the signal generator (-losses) +/- 5 dB. When varying the level in the range -30 to -102 dBm the reading should then follow within +/-5 dB.

RM-364 System Module Description 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-4U battery is used. Table 9 Nominal voltages Voltage Voltage [V] Condition General Conditions Nominal voltage 4.0 Lower extreme voltage 3.

RM-364 System Module Description Mode Description 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. USB, SIM, μSD Micro USB The micro 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.

RM-364 System Module Description µSD card interface Figure 26 µSD card interface The µSD card is connected to the engine by an external level shifter. Supplied voltages: • VMMC: 2.85 V (from level shifter) • VIO: 1.8 V (from AVILMA) The card removal is detected by a push detect switch. Hot swap is supported, which means that the card may be plugged in/out at any time, without removing the battery. Camera concept This phone has two cameras: • A main 2.0 megapixel camera with 8x zoom and a LED flash.

RM-364 System Module Description Audio concept The functional core of the audio hardware is built around EM ASIC N2200 and RAP. N2200 provides an interface for the trancducers. Integrated hands free (IHF) stereo speakers are driven by D-class audio amplifiers. There are three audio transducers: • 1digital microphone • 1 earpiece • 1 IHF (internal handsfree) speaker N2200 also provides an output for the vibra motor.

RM-364 System Module Description Hand portable (HP) mode Microphone X Earpiece X Speaker Internal hands free (IHF) mode X X 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. 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.

RM-364 System Module Description Bluetooth Bluetooth 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 single module. From a functional point of view they, however, have nothing in common.

RM-364 System Module Description Figure 29 FM interface The FM radio is an integrated circuit, controlled by MCU software through a serial bus interface. The wires of the headset are used as poles of the antenna, and no other antenna is needed for FM radio reception. In addition to the Bluetooth unit the FM radio is provided with LDO (low drop out) voltage 2V8_FM_LCD. The radio has an automatic band search function, which can search for a strong write/read signal from a certain frequency.
