1. Safety Precautions 1-1. Repair Precaution ● Repair in Shield Box, during detailed tuning. Take specially care of tuning or test, because specipicty of cellular phone is sensitive for surrounding interference(RF noise). ● Be careful to use a kind of magnetic object or tool, because performance of parts is damaged by the influence of manetic force. ● Surely use a standard screwdriver when you disassemble this product, otherwise screw will be worn away. ● Use a thicken twisted wire when you measure level.
Safety Precautions 1-2. ESD(Electrostatically Sensitive Devices) Precaution Several semiconductor may be damaged easilly by static electricity. Such parts are called by ESD(Electrostatically Sensitive Devices), for example IC,BGA chip etc. Read Precaution below. You can prevent from ESD damage by static electricity. ● Remove static electricity remained your body before you touch semiconductor or parts with semiconductor.

Array course control Software Downloading 4-1. Downloading Binary Files • Three binary files for downloading X830. – X830XXYY.s3 : Main source code binary. 4-2. Pre-requsite for Downloading • Downloader Program(OptiFlash.
Array course control 4-3. S/W Downloader Program 1. Load the binary download program by executing the “OptiFlash.exe” 2. Select the “Options” -> “Settings” -> “Generic” -> “Specify hardware platform”. Choose hardware platform for the downloader file setting. Set the everything else as the default values which are shown below 3.
Array course control Up to twelve ports are supported. Additionally you can select the maximum transfer speed OptiFlash will use to communicate with the phone. However, OptiFlash will use a slower speed if either the PC’s or the phone’s serial hardware is incapable of handling the selected speed 4.
Array course control Set the directory path and choose the latest s/w binary, for example XC30XXYY.s3”, for the downloader binary setting. Make sure that not to change the reserved memory regions. In case of C130 the reserved regions are : -0x00fc0000 – 0x00ffffff 5. Click “OK” button then press “Flash”.
Array course control (Before pressing ‘Flash’ button, push the button ‘*’and ‘END’ at the same time. Then press ‘Flash’.) Downloader will upload the binary file as below for the downloading. 6. When downloading is finished successfully, there is a “All is well” message. 7. After finishing downloading, Certain memory resets should be done to guarantee the normal performance. 8. Confirm the downloaded version name and etc.
