SOLUTION
• 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 IEEE 802.11 b/g.
• 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 IEEE 802.11 b/g.
• 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.
• Functions using the wireless network (Wi-Fi) such as Epicurious, Calendar, WeatherBug, AP
News, Pandora and Twitter can be used only if the refrigerator is connected to your wireless
network (Wi-Fi).
• If there are any other devices connected to the wireless network, please check the connection
status of the devices.
• Because these services depend on data downloaded from the internet, the information
updates can be delayed or cut depending on the status of the internet connection.
• Turn the power of both the Wireless AP and the Fridge off and on.
• If the network connection of an external device the Fridge detects was shut down abnormally (by
a power failure or by moving out of range, etc), the device's network information will remain on
the network list (as stipulated by DLNA specifications), but its connection will not be available.
• Select the Photos function - All Share, and then search for the external devices again.
• Click the "Dispenser OK" button which is at the bottom of display .
If the ""Dispenser OK" button is changed to "Complete", turn the power off and on again.
It is correct to show the "touch panel calibration screen"
