RM-264 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.

RM-264 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-264 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-264 System Module Introduction Phone description RAP is the main digital baseband ASIC in the phone. It contains functionality for both WCDMA and 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.

RM-264 System Module Board and module connections Energy management Battery and charging BL-6P battery The phone is powered by a 3-pole BL-6P 850 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 18 Battery pin order Page 5 –8 COMPANY CONFIDENTIAL Copyright © 2007 Nokia. All rights reserved.
PAGE 109
RM-264 System Module The battery temperature can be measured from the UI flex. Battery connector The battery connector is a blade connector. It has three blades; • BSI (Battery size indicator) • GND (Ground) • VBAT (Battery voltage) The BSI line is used to recognize the battery capacity by a battery internal pull down resistor. Figure 19 Battery connector Charging This phone is charged through the µUSB interface only (there is no separate connector for a charger).

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).
PAGE 111
RM-264 System Module Figure 20 Clocking scheme USB, SIM, MMC 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. This phone is provided with a specific connector for µUSB. SIM interface The device has one SIM (Subscriber Identification Module) interface.
PAGE 112
RM-264 System Module 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 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.

RM-264 System Module Most headsets, or other external audio accessories, can only be connected via bluetooth. Figure 23 Audio block diagram Internal audio The internal audio components are used in these modes: 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).
PAGE 116
RM-264 System Module 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.

RM-264 System Module Figure 24 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.

RM-264 System Module Environmental condition Humidity and water resistance Ambient temperature Notes Relative humidity range is 5 to 95%. Condensed or dripping water may cause intermittent malfunctions. Protection against dripping water has to be implemented in (enclosure) mechanics. Continuous dampness will cause permanent damage to the module. Issue 1 COMPANY CONFIDENTIAL Copyright © 2007 Nokia. All rights reserved.
