RM-170; RM-171 Camera Module Troubleshooting Nokia Customer Care Figure 61 Camera module cross section and assembly principle Figure 62 Camera module bottom view including serial numbering The camera module as a component is not a repairable part, meaning that the components inside the module may not be changed. Cleaning dust from the front face is allowed only. Use clean compressed air. The camera module uses socket type connecting. For versioning, laser marked serial numbering is used on the PWB.

PAGE 187
RM-170; RM-171 Camera Module Troubleshooting Nokia Customer Care If dust particles are found on the sensor, this is classified as a manufacturing error of the module, and the camera should be replaced. Any particles inside the cavity between the protection window and the lens have most probably been trapped there in the assembly phase at a Nokia factory. Unauthorized disassembling of the product can also be the root of the problem.

RM-170; RM-171 Camera Module Troubleshooting Nokia Customer Care It should be noted that the effects of any dirt in images can vary much. It may be difficult to judge whether the window has been dirty or if something else is wrong. Therefore, the cleanness of the protection window should always be checked and the window should be wiped clean with a suitable cloth.

RM-170; RM-171 System Module Nokia Customer Care MicroSD interface The MicroSD card interface is electrically and functionally compatible with SD card interface. SD card interface is a 1-bit serial IF connected to RAP. IF includes 1.8V-2.85V level shifter and 2.85V LDO regulator (combined into one package) and an SD ASIP. Card detection is implemented by using a transistor switch connected to data3 pin of microSD card.

RM-170; RM-171 System Module Nokia Customer Care SIM/USIM The device has one SIM (Subscriber Identification Module) interface and the SIM card locates under the battery. SIM interface consists of internal interface between RAP and EM ASIC (N2200) and an external interface between Retu and SIM contacts. SIM interface functionality is located in RAP while EM ASIC (N2200) takes care of power up/down, card detection, ATR counting and level shifting.
PAGE 208
RM-170; RM-171 System Module Nokia Customer Care Due to location of the SIM card, removal of the battery causes quick power down of the SIM IF. The EM ASIC (N2200) SIM1 interface supports both the 1.8V and 3.0V SIM cards. SIM interface voltage is first 1.8V when the SIM card is inserted and if the card does not response to the ATR (answer to reset) 3V interface voltage is used. Battery interface The battery interface supports a 3-pole battery interface.

RM-170; RM-171 System Module Nokia Customer Care The received signal goes from the GSM antenna to the front end module (FEM) which includes switches from band selection. FEM is followed by dedicated SAW filters which are dual packaged so that one holds SAWs for 850 and 900 and the other for 1800 and 1900 bands. The SAW filters are followed by integrated LNAs residing in N7505. The LNAs are followed by demodulators which downconvert the signal to baseband I and Q signals.

The error amplifier resides in N7505 and it controls the transmitter power of GSM. Detector output from the FEM gives a DC level proportional to the output power. The DC voltage is fed to the negative input of the error amplifier where it is compared to the level of the reference signal, TXC.
