SOLUTION
• Press the Reset button over one second to reset the memory. With this, the user
information is not to be reset.
• If the "A SD/MMC 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.
• At the Settings-Display, the Screensaver Running Time can be set.
• 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 at the Settings.
• Check if the power for the wireless AP is on.
• Check if the wireless AP supports IEEE802.11b/g/n.
• If the wireless AP is located away from the Fridge, move the wireless AP closer to the
Fridge and check if it is detected.
• Turn the power of both the Wireless AP and the Fridge off and on.
• Check if the wireless AP supports IEEE802.11b/g/n.
• Check the status of the internet connection of the wireless AP.
• 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 --->WiFi Networks, and then look on
the bottom of the screen that lists the available network connections.)
• Turn the power of both the Wireless AP and the Fridge off and on.
• Refer to the wireless AP manual and reset the password.
