ESD PRECAUTIONSElectrostatically Sensitive Devices (ESD)Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated circuits and some field-effect transistors and semiconductor chip components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity. 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a grounded-tip soldering iron to solder or unsolder ESD devices. 4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges sufficient to damage ESD devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESD devices. 6. Do not remove a replacement ESD device from its protective package until immediately before you are ready to install it. (Most replacement ESD devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive materials). 7. Immediately before removing the protective material from the leads of a replacement ESD device, touch the protective material to the chassis or circuit assembly into which the device will by installed. CAUTION : BE SURE NO POWER IS APPLIED TO THE CHASSIS OR CIRCUIT, AND OBSERVE ALL OTHER SAFETY PRECAUTIONS. 8. Minimize bodily motions when handing unpackaged replacement ESD devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ESD device).

SOFTWARE REPLACE METHOD

1. After booting the unit without the Navi SD card, insert the Update SD card. 2. Enter the setup screen and press the Enter key on the remote controller for a long time. (About 5~8 seconds) 3. Update Program will be displayed on the screen.

1. After booting the unit without the Navi SD card and entering the setup screen, press the Arrow key on the right side of the front panel for more than 5 seconds. (Press and wait for 5 seconds after switching to up direction) Or press the Enter key on the remote controller for a long time. 2. Windows Explorer will be displayed. 3. Insert the Update SD card. 4. After selecting my device / SD memory, run Hobbiton.

1. Run the Update Program. 2. Press the Application button. 3. When you see the Copy Completed (xxx files/xxx files) message, the Application SW update is completed. If you see the message saying xxx file(s) Missed, it means that some files are not copied. Reset the power and then repeat from step 1. 4. When it is completed, press the Exit button. 5. Remove the SD card and then reboot the unit.

1. Run the Update Program. 2. Press the Micom button. 3. The progress increases by 10%. 4. When the progress reaches 100%, Program Ok !!! message will be displayed and Micom update is completed. 5. If there are no files to update, message saying File could not be opened !!! will be displayed. 6. When the process is completed, press the Exit button. 7. Remove the SD card and then reboot the unit.

1. Run the Update Program. 2. Press the BT Handsfree button. 3. When BT Firmware Upgrade Completed. Is displayed, update is completed. (This is irrelevant from the displayed %. If the BT Firmware Upgrade Completed. message is displayed even when the displayed progress is not 100%, it is completed.)LGE Internal Use Only

4. When the update fails, it will automatically retry the update again. When the process is not completed even when the progress is over 200%, update has failed. In this case, press the Exit button and then reset the unit to retry the update. 5. If update is not required, BT Firmware Upgrade Unnecessary. Message will be displayed. In this case press the Exit button or update other SW. But, you cannot update the Kernel in this condition. You must reset the unit to update the Kernel. 6. If there is no BT firmware in the SD card, No BT Files message will be displayed. 7. When it is completed, press the Exit button. 8. Remove the SD card and then reboot the unit. * Reference - Update of BT firmware can take maximum of 10 minutes. If difference between the version of the existing firmware and the new version is small, the time to update is reduced. Generally, it requires about 5~6 minutes. - The reason the Micom firmware update takes longer than the time to update other SW is because it requires more time to
