RM-410; RM-411 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.

RM-410; RM-411 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.

RM-410; RM-411 System Module Introduction Phone description RAP is the main digital baseband ASIC in the phone. It contains functionality for 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 109
RM-410; RM-411 System Module 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 22 Battery pin order The battery temperature can be measured from the UI flex. Issue 1 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.
PAGE 110
RM-410; RM-411 System Module 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 23 Battery connector Charging This phone is charged through a separate charger connector.
PAGE 111
RM-410; RM-411 System Module 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 112
RM-410; RM-411 System Module Figure 24 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 113
RM-410; RM-411 System Module User interface Display module The interconnection between the LCD module and the engine is implemented with a 24-pin board-to-board connector. The LCD module does not require any tuning in service.
PAGE 114
RM-410; RM-411 System Module Audio concept This phone has a conventional solution on earpiece and vibra. Both are handled by AVILMA N2200. Two integrated handsfree speakers are driven by an additional amplifier also handled by AVILMA. The microphone has a digital interface and its RF-filtered lines are directly connected to RAP D2800 for processing. Since this phone has focus on audio playback, it contains improved circuits for audio handling.

RM-410; RM-411 System Module AV connector The AV connector is used to connect headsets both in the handsfree phone function and for using the phone as a media player (see the audio concept heading). The six pins are used in accordance with the table below. A connected male connector is detected on pin 6 (PLUG_DET). Note: Only use an approved cable for connecting to the AV connector ( e.g. headset HS-45).

RM-410; RM-411 System Module Pin Signal name Direction Description 4 HS_EAR_R Output Audio out 5 HS_EAR_L Output Audio out 6 PLUG_DET Input Plug detection 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.

RM-410; RM-411 System Module 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. Figure 26 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.

RM-410; RM-411 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 © 2008 Nokia. All rights reserved.
