Spectrum analyzer level values depend on the probe type and should be validated using a known good sample. The levels that are given here are measured using a high frequency probe. Spectrum analyzer should be at least capable of measuring signal upto 4.5 GHz. Page 7–44 Company Confidential 9235618 (Issue 2) Copyright ©2005 Nokia. All Rights Reserved.

Sometimes blurring may even occur in daytime, if the image is taken very carelessly. See the figure below for an example. Page 8–6 Company Confidential 9235618 (Issue 2) Copyright ©2005 Nokia. All Rights Reserved.

The electricity frequency used is automatically detected by the camera module. In some very few countries, both 50 and 60 Hz networks are present and thus probability for the phenomenon increases. Flickering occurs also under high artificial illumination level. Page 8–8 Company Confidential 9235618 (Issue 2) Copyright ©2005 Nokia. All Rights Reserved.

These spots are searched for in the manufacturing phase, but it is possible that the camera body cavity contains a particle, which may move Page 8–10 Company Confidential 9235618 (Issue 2) Copyright ©2005 Nokia. All Rights Reserved.
Page 231: Testing Camera Image Sharpness
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.

USB but does not support FBUS. The implementation of the ACI bus in RM-25 has been made possible by implementing the BSI, Battery Size Indication, a little different from most Nokia phones. Functional description The heart of the BB is UPP_WD2, which includes the MCU, DSP and Digital Control Logic. Power is supplied by the UEME ASIC and a number of discrete regulators.
Page 242: Bb Description
• In PWR_ON mode SW is running and controlling the system. • SLEEP mode is entered from PWR_ON mode when the system’s activity is low (SLEEPX controlled by SW). • FLASHING mode is for production SW download. Page 9–6 Company Confidential 9235618 (Issue 2) Copyright ©2005 Nokia. All Rights Reserved.
Page 243: Clocking Scheme
FM radio uses 32kHz, the SleepClk. In SLEEP mode, the VCXO is off. UEME generates low frequency clock signal (32.768 kHz) that is fed to UPP_WD2, Bluetooth and ZOCUS. 9235618 (Issue 2) Company Confidential Page 9–7 Copyright ©2005 Nokia. All Rights Reserved.

This happens when the battery is suddenly removed. UEME’s state machine notices battery removal after the battery voltage has been below VCOFF- for 5 us and enters PWR_OFF mode. PURX is set low and all UEME’s regulators are disabled. 9235618 (Issue 2) Company Confidential Page 9–9 Copyright ©2005 Nokia. All Rights Reserved.

Between UPP_WD2 and UEME, the audio signals are transferred in digital format using signals MICDATA and EARDATA. Ringing tones and warning/info tones are to be produced to the IHF speaker. Page 9–12 Company Confidential 9235618 (Issue 2) Copyright ©2005 Nokia. All Rights Reserved.
