RM-303 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-303 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-303 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-303 System Module SIM interface The device has one SIM (Subscriber Identification Module) interface. It is only accessible if battery is removed. The SIM interface consists of an internal interface between RAP and EM ASIC AVILMA (N2200), and of an external interface between N2200 and SIM contacts. 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.

RM-303 System Module µSD card interface The µSD card is connected to the engine by an external level shifter and ESD protection filter. 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. 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.
