RM-313 BB Troubleshooting and Tuning Guide Steps 1. Verify with a working display that the fault is not on the display module itself. The display module cannot be repaired. 2. Check that the cellular engine is working normally. i To check the functionality, connect the phone to a docking station. ii StartPhoenix service software. iii Read the phone information to check that also the application engine is functioning normally (you should be able to read the APE ID). 3.

RM-313 BB Troubleshooting and Tuning Guide Display and keyboard backlight troubleshooting Context The device has one LED driver that provides current for both display and keyboard backlights and another LED driver that provides current for ITU and side key backlights. Keyboard backlights are turned ON only in dark conditions. This is controlled by the Ambient Light Sensor (ALS). Also the brightness of the display is adjusted by the ambient light sensor.
PAGE 99
RM-313 BB Troubleshooting and Tuning Guide Current pump LED driver troubleshooting Troubleshooting flow Ambient Light Sensor (ALS) troubleshooting Context • If ALS (Poliwag) is broken, replace it. • After replacing the ALS, ALS re-tuning is required for example if calibration values of the new sensor are lost (see instructions later in this document). • When carrying out the ALS calibration procedure, it is required to have a reference phone, which includes calibrated ALS.
PAGE 100
RM-313 BB Troubleshooting and Tuning Guide • Phoenix has an ambient light sensor calibration tool for changing calibration values. Concerning Poliwag ALS, there is no need for performing a pull-up resistor calibration (as for earlier Ambient Light Sensors). Re-tune Poliwag ALS as follows: Steps 1. Connect the reference phone to Phoenix and set the phone (e.g. on the table) so that the amount of ambient light is as stabile as possible seen by Poliwag ALS.

After writing a value to IPhoto (reference value), press the Calibrate button. Stop iterating when the coefficient is equal to the co-efficient calculated in bullet 6. Note that decimal numbers should be used in the iteration in order to achieve enough precision (e.g 23.2455). 8.

RM-313 Camera Module Troubleshooting Xenon flash troubleshooting Introduction to camera module troubleshooting Background, tools and terminology Faults or complaints in camera operation can be roughly categorised into two subgroups: 1 Flash is not functional at all; no image can be taken.
PAGE 156
RM-313 Camera Module Troubleshooting The effect of image taking conditions on image quality There are some factors, which may cause poor image quality, if not taken into account by the end user when shooting images, and thus may result in complaints. The items listed are normal to camera and Xenon flash operation and are not a reason for changing the camera or Xenon flash modules. Distance to target (too close) The Xenon module may overexpose the image if the object is too close to the camera.

RM-313 Camera Module Troubleshooting Xenon flash construction For RM-313, Tabasco 1 module (4860024) is used. The feedback sensor is not used, only 1 capacitor. The Xenon flash module as a component is not a repairable part i.e. components / parts in the module cannot be changed. Cleaning dust from the lens is the only allowable operation, do this by using clean compressed air.
PAGE 159
RM-313 Camera Module Troubleshooting Figure 38 Possible sources of electric shocks Handling instructions With an undamaged module there is no possibility of an electric shock. However, the possible damage cannot always be seen and therefore insulating glows should be always worn, when handling the Xenon module. Disassembling the module is never allowed, because there is no way to fully discharge the module and also repairing is impossible.
PAGE 160
RM-313 Camera Module Troubleshooting Testing Flash power For testing flash power, take an image with the flash in total darkness (ambient light level < 1 lux) from the target about 80cm – 1m away from you. If the flash is working normally with adequate power level the image is correctly exposed from 80cm – 1m distances. Remember that the brightness level in the corners is always less than in the center of the image, due to camera and flash optics.

RM-313 Camera Module Troubleshooting Troubleshooting Xenon flash For testing flash overall functionality, take an image with the flash and monitor same time whether the Xenon module flashes or not. To do this test use always FORCED FLASH mode in the phone, not AUTOMATIC mode. FORCED FLASH mode forces the Xenon module to flash even if there is some ambient light in present. Assumption is that other components (UI.etc.) are working correctly and only flash & driver functionality are troubleshooted.

RM-313 System Module Transmitter (TX) The digital baseband signal (eg. from the microphone) is converted to an analogue signal, which is then amplified and transmitted from the antenna. The frequency of this signal can be tuned to match the bandwith of the system in use (eg. GSM900). The transmitter functions are implemented in the RF ASIC. Even though the GSM and WCDMA signals are sent via different components, the principles of the transmission is the same.
