; The actual inner temperature varies depending on the food status, as the indicated setting temperature is a target temperature,
not actual temperature within refrigerator.
; Refrigeration function is weak in the initial time.
Please adjust temperature as above after using refrigerator for minimum 1 ~ 2 days.

FUNCTIONS
A. “TEMP” Button
1. Temperature control of Refrigerator compartment
2. 5 step mode of successive temperature mode
3. Initial mode by power input: step “NOR”
4. Temperature will be set if the button doesn’t get pressed again within 5 sec.
- Whenever pressing “TEMP” button, setting is repeated in the order of
“NOR” →“MAX-NOR” →“MAX” →“MIN” →“MIN-NOR” (LED LAMP ON)
B. Temperature of Refrigerator Control
1. COMP and FAN will be controlled by the on/off condition of each mode.1
2. Temperature Difference of Refrigerator each step :
3. Temperature of Refrigerator
at step “NOR” OFF point: is -1.2C
4. Refrigerator ON/OFF Temp.
Difference: 3.4C
C. “S-COOL” MODE
1. Press S-COOL SWITCH
and make S-COOL led lamp on.
2. COMP & FAN are on until R-sensor
reaches to “Over Refrigeration
OFF Point”, -7C
3. After the reach of -7°C , STEP “MAX” mode continues.
4. When “S-COOL” MODE (Quick Refrigeration Mode)
lasts for about 40 minutes, it returns to general
operation mode.
D. Temperature of Freezer Control
-It will be only controlled by using
“KNOB F LOUVER” in Freezer.
