RM-436 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.
PAGE 7
RM-436 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-436 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-436 System Module Board and module connections Energy management Battery and charging BL-4CT battery The phone is powered by a 3-pole BL-4CT 860 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 Page 5 –8 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.

RM-436 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 23 Battery connector Charging This phone is charged through a separate charger connector.

RM-436 System Module Voltage Voltage [V] Condition Vcoff- 2.6 ± 0.1 On to off 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 109
RM-436 System Module The SIM IF is shown in the following figure: 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.

RM-436 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. Page 5 –18 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.
