RM-164 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-164 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-164 RF Troubleshooting and Manual Tuning Guide Figure 18 Some RF test points Receiver troubleshooting Introduction to RX troubleshooting Rx can be tested by making a phone call or in the local mode. For the local mode testing, use Phoenix service software. The main Rx troubleshooting measurement is RSSI measurement. This test measures the signal strength of the received signal. I and Q branches can be measured separately.
PAGE 111
RM-164 RF Troubleshooting and Manual Tuning Guide 3. Connect an RF cable between the RF connector of the module test jig and measurement equipment. Note: Make sure that all connections are made to the correct RF connector. 4. Set Rx on. i Set the phone module to the test jig and start Phoenix service software. ii Initialize connection to the phone. (With the FPS-10 prommer use FPS10_USB or FPS10_TCP drivers, depending on connection type. When using DAU-9S select FBUS).

The RSSI level must be the same value as that which is set at the signal generator (-90 dBm).
PAGE 117
RM-164 RF Troubleshooting and Manual Tuning Guide 3. Connect an RF cable between the RF connector of the module test jig (MJ-133) and measurement equipment or alternatively use a 50 Ω (at least 2 W) dummy load in the module test jig RF connector, otherwise GSM may be damaged. Note: Make sure that all connections are made to the correct RF connector. Normally a spectrum analyser is used as measurement equipment. Note: The maximum input power of a spectrum analyser is +30 dBm.
PAGE 121
RM-164 RF Troubleshooting and Manual Tuning Guide RF tunings Introduction to RF tunings Important: Only perform RF tunings if: • one or more of the RF components have been replaced • flash memory chip is replaced or corrupted. RF calibration is always performed with the help of a product-specific module jig (MJ-133), never with an RF coupler. Using an RF coupler in the calibration phase will cause a complete mistuning of the RF part. Important: After RF component replacements, always use autotuning.

Next actions Repeat steps 6 to 9for GSM1800 and GSM1900 Rx band filter response compensation (GSM) Prerequisites Rx calibration must be performed before the Rx band filter response compensation. Context On each GSM Rx band, there is a band filter in front of the RF ASIC front end. The amplitude ripple caused by these filters causes ripple to the RSSI measurement, and therefore calibration is needed.

RM-164 System module Phone description Introduction This chapter describes the baseband module including engine, power management, interfaces, audio etc. The baseband is based on BB5.0 with a RAPGSM main processor and Retu/Tahvo energy management. All blocks that require high voltage process are in Tahvo and all other in Retu. The RF part is based on the ASIC Ahne. RM-164 is a quadband phone operating on the GSM850/900/1800/1900 bands.
PAGE 144
RM-164 System module Engine Engine modules The engine contains • RF module with Ahne ASIC • Main processor with integrated memory (Baseband) • Energy management - Retu and Tahvo (Baseband) • SDRAM, NOR and NAND flash memories RF engine The RF module performs the high frequency operations of the engine for GSM. In both transmitter and receiver, the modulator and demodulator operate at the channel frequency.

RM-164 System module • Energy management control • Supply voltage generation • Charge control • Digital core supply • Current control for LED supply Retu The blocks that do not have special needs are included in Retu. Retu controls for example: • Audio block • SIM • FM radio Modes of operation The functional behavior can be divided into seven different states.

RM-164 System module Battery connector The battery connector has three poles: • 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. Charging This phone is charged through the micro USB connector.

RM-164 System module Camera Figure 30 Camera interface This phone is equipped with a 2 megapixel camera. The module has only one operating mode; raw pixel data output. A hardware accelerator includes features like pixel defect correction, colour interpolation, image sharpness enhancement, selective noise filtering, cropping and scaling. The image can be JPEG-compressed in real-time. The hardware accelerator also performs sensor housekeeping functions such as automatic exposure and white balance controls.

RM-164 System module SIM Logic level shifting The SIM interface can support 3V and 1.8V SIM cards. SIM Power up/down The SIM power up/down sequence is generated in Retu. This means that Retu generates the reset switch (RST) signal to the SIM. In addition, the SIMCardDet signal is connected to Retu. The SIM interface is powered up when the SIMCardDet signal indicates “card in”. Issue 1 COMPANY CONFIDENTIAL Copyright © 2007 Nokia. All rights reserved.
