• The actual inner temperature varies depending on the food status, as the indicated setting temperature is a target
temperature, not the actual temperature within the refrigerator.
• A newly installed refrigerator will take 24 hours minimum for temperatures to stabilize. The temperature should be
checked and adjusted as necessary after 2 or 3 days.
2-1-2. LCD Back Light Control (GR-L267, G267, P277)
1. In order to see the LCD display more easily, the backlight is turned on for one minute at the initial application of power, for
20 seconds when buttons are pressed, when a door is opened, and for 20 seconds after the door is closed.
2. When any display button is pressed while the backlight is off, the bell sounds and the backlight is turned on, but the
button function is not performed. In other words, pressing any button turns on the backlight but does not cause any
function to be initiated.
3. To check the LCD graphic and back light ON/OFF status, press and hold the EXPRESS/JET FRZ and FREEZER buttons.
This will turn the back light on and illuminate all of the graphics. When the buttons are released, the graphic display
returns to its previous setting and the back light is turned off.
2-1-3. Room temperature display function
1. The sensor for the ROOM TEMP display is located under the upper right hinge cover. Factors such as air flow, lighting,
and other appliances operating within the room, may cause the display to differ from other temperature displays in the
same room.
2. Ambient temperature is displayed between -9°C and 49°C. Temperatures -10°C and below are displayed as Lo and
temperatures 49°C and above are displayed as Hi . If the ambient temperature sensor fails, Er will be displayed.
