4. TROUBLESHOOTING
4-1-4) Restoration of Previous Settings upon Instant Power Outage
1) If the Display Panel is initialized by the instant power outage, it will cause customer inquiries.
To prevent this, when the power is restored, the previous settings will be restored or reset based on the
inside temperature of the Freezer Compartment.
2) Upon the initial power on, it checks its Freezer temperature. When it is lower than +10℃, it is to be
considered as an instant power failure and it brings back all its previous operation functions (such as Power
Freeze, Vacation, Fridge, Freezer,Cool Select Zone, etc) related to the panel display.
3) When it is higher than +10℃, it is to be considered as a long-period power failure and it will initialize the
panel display. (Freezer : Automatically set to -19℃ → MID, Fridge : Automatically set to 3℃ → MID)

1) During the Normal Operation, press the Freezer + Fridge buttons for 7 seconds.

LEDs on the Display Panel will blink at the interval of 0.5 seconds for 3 seconds.
2) At this time, release the Freezer + Fridge buttons and press the Freezer button (it sends out "Ding Dong"
sound.) Then, it shifts to the Demo mode.

Compressor does not operate.
