ESD PRECAUTIONSElectrostatically Sensitive Devices (ESD)Some semiconductor (solid state) devices can be damaged easily by static electricity. Such componentscommonly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integratedcircuits and some field-effect transistors and semiconductor chip components. The following techniques shouldbe 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 acommercially available discharging wrist strap device, which should be removed for potential shock reasonsprior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive surfacesuch 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 byconductive foam, aluminum foil or comparable conductive materials).
7. Immediately before removing the protective material from the leads of a replacement ESD device, touch theprotective 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 OTHERSAFETY PRECAUTIONS.
8. Minimize bodily motions when handing unpackaged replacement ESD devices. (Otherwise harmless motionsuch as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can gener-ate static electricity sufficient to damage an ESD device).
CAUTION. GRAPHIC SYMBOLS

- Touch agree button- LAN9700R set shows tuner screen.- Change into DVD source by pressing a SRC key
or select DVD source in Source screen.- We can enter source screen by touch source
button at left & upper corner.
Step 2 : Insert DVD F/W Disc
- Insert a DVD F/W Update Disc- Press an enter key of front panel after DVD F/W
Disc popup shows
Step 3 : DVD F/W updating
- DVD F/W update begins(Reading step --> Erasing step --> Writing step --> Verifying step)
- DONOT STOP or POWER OFF during F/Wupdating.
Step 4 : Remove DVD F/W disc
- If the verifying step is finished then displayscreen is changing and it shows a disc readingpopup and DVD F/W disc popup again.
- eject the disc by pressing a eject button.- Set power off
Step 5 : Additional Info
- If you see noises such as horizontal lines onscreen then take below procedure
step A) Power on and change into DVD sourceand remove disc.
step B) Press pause button of remote controllerfor 10 sec.

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 keyon the right side of the front panel for more than 5 seconds. (Press and wait for 5 seconds afterswitching 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 com-
pleted. 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 dis-played progress is not 100%, it is completed.)

4. When the update fails, it will automatically retry the update again. When the process is not complet-ed even when the progress is over 200%, update has failed. In this case, press the Exit button andthen reset the unit to retry the update.
5. If update is not required, BT Firmware Upgrade Unnecessary. Message will be displayed. In thiscase press the Exit button or update other SW. But, you cannot update the Kernel in this condition. You must reset the unit to update theKernel.
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 requiresabout 5~6 minutes.
- The reason the Micom firmware update takes longer than the time to update other SW is becauseit requires more time to read the software to compare to the existing version.
- To update the BT firmware for other models, you must first disassemble the unit. But forLAN9700R, you can update the unit using only the SD card without having to disassemble the unit,this is a major improvement in work productivity.
1. Run the Update Program. 2. Press the Kernel NB0 button.3. Wait until Kernel NB0 Upgrade Completed message is displayed. 4. After pressing the Exit button, remove the SD card and insert the original SD card in Navi to reboot
the unit. * Caution: If you turn off the power or press the Exit button while updating the Kernel, it may be
impossible to recover.
1. Run the Update Program. 2. Press the Update All button. It will be updated in the order of Application -> Micom -> BT -> Kernel.3. After updating the BT firmware,
Notice: Kernel not completed. Reset and then Upgrade KernelWhen the above message is displayed, Kernel update is not completed yet.In this case, reset the unit and update the Kernel.
4. When ALL SW Upgrade Completed. Is displayed, the update for all SW is completed. Press theExit button and then remove the SD cards. Insert the Navi SD card and then reset the unit.
