RH-99; RH-100; RH-105; RH-106 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.

RH-99; RH-100; RH-105; RH-106 Baseband troubleshooting General baseband troubleshooting Important test points Introduction Measuring power suppliers is usually earlier step during troubleshooting. The following picture illustrates the test points for power suppliers.

RH-99; RH-100; RH-105; RH-106 Baseband troubleshooting Phone doesn't set FBUS_TX line low Because of the use of uBGA components it is not possible to verify if there is a short circuit in control- and address lines of MCU (UPP) and memory (flash).

PAGE 55
RH-99; RH-100; RH-105; RH-106 Baseband troubleshooting Phone doesn't switch on Troubleshooting flow This means that the phone does not use any current at all when the supply is connected and/or power key is pressed. It is assumed that the voltage supplied is 3.6VDC. The UEMCLite/Litti will prevent any functionality at battery/supply levels below 2.9VDC. Figure 10 Troubleshooting when the phone doesn't switch on Issue 2 COMPANY CONFIDENTIAL Copyright © 2007 Nokia. All rights reserved.

RH-99; RH-100; RH-105; RH-106 Baseband troubleshooting Switch off Troubleshooting flow If this kind of a failure is presenting itself immediately after FLALI, it is most likely caused by ASIC's missing contact with PWB. If the MCU doesn’t service the watchdog register within the UEMCLite, the operations watchdog will run out after approximately 32 seconds. Unfortunately, the service routine can not be measured.

Only few signals can be tested since several signals is 'buried' in one or more of the inner layers of the PWB.

RH-99; RH-100; RH-105; RH-106 Baseband troubleshooting Figure 13 No registering or call SIM related faults Insert SIM card fault Troubleshooting flow The hardware of the SIM interface from UEMC/Litti (D2901) to the SIM connector (X2700) can be tested without a SIM card. When the power is switched on the phone first check for a 1.8V SIM card and then a 3V SIM card. The phone will try this four times, where after it will display ”Insert SIM card”.

Apply a RF-cable to the RF-connector to allow the transmitted signal act as normal. RF-cable should be connected to an attenuator at least 10dB before connected to the measurement equipment, otherwise the PA may be damaged. 2.

RH-99; RH-100; RH-105; RH-106 RF troubleshooting Crystal troubleshooting Introduction 26 MHz Reference Oscillator (VCXO) The 26 MHz oscillator is located near the UPPCosto IC (D7402). The coarse frequency for this oscillator is set by an external crystal (B7402). The 26 MHz signal from the crystal can be measured by probing C7436. The level at this point is approx. 276mVpp. Example Signal Measured at VCXO output (C7436).

RH-99; RH-100; RH-105; RH-106 System module Block diagram System module block diagram The main functionality of the BB4.1 is concentrated on two ASICs, the digital/RF ASIC is called the UPPCosto and the mixed signal ASIC, the LITTI. The program code is stored in the external FLASH memory. The simplified BB4.1 block diagram is presented below. Figure 77 Module block diagram Functional description The UPPCosto ASIC is designed to work in DCT4 cellular phone engines developed only for GSM.

RH-99; RH-100; RH-105; RH-106 System module LITTI LITTI is the mixed signal ASIC used in the GSMCost 4.0 engine. The main functionality is: Voltage regulation, battery charge control, audio codec, A/D conversion, various drivers, Real Time Clock (RTC), system logic, and digital interfaces. Modes of operation BB4.1 has five different functional modes: • No supply: In NO_SUPPLY mode, the phone has no supply voltage.

Input and output selection, and gain control is performed inside UEMCLite. DTMF-tones and other audio tones are generated and encoded by UPP and transmitted to UEMCLite for decoding. The vibra has is driven by PWM signal, generating vibration by rotating an un-balanced mass (counter weight).
