RM-333; RM-334; RM-335 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.

The GPS components are located on small 2nd PWB. Satellite signals are picked up by the phones GPS antenna in the C-cover. The signal is then routed through a filter before being processed by the GPS5350 receiver ASIC. Verify that the GPS voltage and clock signal levels are as in RM-333 GPS schematics.

Any particles inside the cavity between the protection window and 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. However, in most cases it should be possible to remove the particle(s) by using clean compressed air.
• If possible, compare the image to another image of the same scene, taken with a different device. Note that the reference device has to be a similar Nokia phone. There are several conditions in which AF operation is challenging for the camera module, i.e. failing from time to time.
The FMTx 2.1 implementation is based on the Silicon Laboratories Si4713 low power FM transmitter device. This device has some state of the art features which have been utilised in the Nokia implementation. Apart from having excellent RF transmitter performance and exceptional AF performance the device offers a number of unique features, including the ability to retune the output stage of the device to ensure optimal matching between the Tx antenna and the output stage of the device.
On RM-333 the _SEN is pulled high by connecting it to VIO. RM-333 uses a loop antenna which is located in the removable C-cover of the device. The loop antenna also acts as the tuning inductor which is required by the Si4713 chip. The location of the antenna in the removable cover means that ESD protection is required to prevent damage to the Si4713 device.
It’s possible that if GP01 and/or GPO2 are not at the correct state when the Si4713 device has power applied then the wrong bus mode could be selected and the handset would be unable to communicate with the device. For RM-333, the bus mode should be I2C. Page 7 –6...
If the _SEN signal is not correct (i.e. not selecting the correct I2C address), then this is also another possible reason why control of the FMTx 2.1 feature might not be possible. For RM-333 the I2C address used for FMTx 2.1 will be 0x63.
Typical maximum swing of these tones will be ~636mV peak to peak. The maximum swing may vary between Nokia handsets but for the FMTx 2.1 implementation, the swing should not be greater than the aforementioned value.

The antenna tuning value is a good indicator of the state of the antenna and the other components connected to the TXO pin. For RM-333 the tuning values should be in the range 0 –...
As ITU keyboard backlights are controlled by the Ambient Light Sensor (ALS) they are turned ON only in dark ambient light. RM-333 has a self-emissive AM OLED display, therefore it does not need LEDs for backlighting Issue 2 COMPANY CONFIDENTIAL Page 8 –21...

General Information RM-335 Product data RM-335 is a 2G variant of the Nokia N85. The key product data differences between the RM-335 (2G) and RM-333 (3G) are described below. RM-335 is a GSM handportable phone, supporting GSM/ GPRS/ EGPRS 850/900/1800/1900. RM-335 does not support WCDMA or WLAN.
RF Troubleshooting RM-335 RF block As RM-335 is a 2G variant of the RM-333/334, there are no WCDMA RF components in the RF block of the RM-335. For example, the following WCDMA RF components are not assembled in RM-335: • N7540 WCDMA PA •...
