RM-484; RM-485; RM-486 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-484 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.
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-484 the _SEN is pulled high by connecting it to VIO. RM-484 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-484, 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-484 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.

If the ‘AutoJump’ tick box is checked then this list will be transmitted to the FM receiver to allow the handset to perform AF jumps. This is dependent on the Nokia handset and if the FM receiver is RDS capable.
Figure 72 Display interface block diagram I/O expanders and keyboards HW53 supports LM8323 I/O expander. RM-484 includes two I/O expanders. They are connected to Rapido via I2C bus. The first I/O expander is located on the system/RF module. ITU keys, multimedia keys and side keys (including volume keys, capture key and keylock switch) are connected to it as a 6x4 matrix.

As ITU and S60 keyboard backlights are controlled by the Ambient Light Sensor (ALS) they are turned ON only in dark ambient light. RM-484 has a self-emissive AM-OLED display, therefore it does not need LEDs for backlighting. Issue 1 COMPANY CONFIDENTIAL Page 8 –23...
