SOLUTION
• Press the Reset button for more than one second to reset the memory.
User information is not reset.
• If the "Memory card is connected" messages do not appear on the screen, check if
the memory type is SD / SDHC / MMC / HS MMC.
• Check if there are photos or images stored in the memory card.
• Check if the images in the memory card are JPEG (JPG) types.
• This is a power-saving function and it is normal.
• On Settings-Display, you can set the Screensaver Running Time.
• Still images can cause permanent damage to the LCD screen.
When you select Screensavers, select a number of themes so the image changes
frequently.
NOTE : Defects caused by this are not be covered by the factory warranty.
• Run the Touch Screen Calibration function in Settings.
• Click the "Dispenser OK" button which is at the bottom of the display.
If the ""Dispenser OK" button changes to "Complete", turn the power off and on
again. The display should show the "Home screen".
• Check if the power for the wireless router is on.
• Check if the wireless router supports IEEE 802.11 b/g/n.
• Check if other devices (Notebook PC, Smart phone etc.) can access the wireless
router. If wireless router can not be accessed by the other devices, the wireless router
probably has a problem.
Please contact with wireless router manufacturer.
• If the wireless router is located far away from the Fridge, move the wireless router
closer to the Fridge and see if the fridge detects it.
• Turn the power of both the Wireless router and the Fridge off and on.
• Check if the wireless router supports IEEE 802.11 b/g/n.
• Check the status of the Internet connection of the wireless router.
• Check if other devices (Notebook PC, Smart phone etc.) can access the wireless
router. If the wireless router can not be accessed by the other devices, the wireless
router is probably the problem.
• Please contact with wireless router manufacturer and Internet service provider
(ISP). Check if the current cost rate plan for the Internet covers the wireless network
connection. If it does, check how many connections are allowed.
• Your Refrigerator may not be able to connect to the Internet because your ISP has
permanently registered the MAC address (a unique identifying number) of your PC or
modem, which it then authenticates each time you connect to the Internet as a way
of preventing unauthorized access.
As your Refrigerator has a different MAC address, your ISP can not authenticate its
MAC address, and your Refrigerator can not connect.
To resolve this problem, ask your ISP about the procedures required to connect
devices other than a PC (such as your Refrigerator) to the Internet.
(To find the MAC address of your Fridge, touch Settings ---> Wi-Fi Networks, and
then look on the bottom of the screen that lists the available network connections.)
• Turn the power of both the Wireless router and the Fridge off and on.
