● !he refrigerator and the free#er have two evaporators.

$iven this independent system% the free#er and the

refrigerator are cooled individually as re&uired and are%

therefore% more efficient. Food odor from the refrigerator

does not affect food in the free#er due to separate air flow

circulation.

(There is no buzzer sound when the exhibition/display mode is canceled by the temperature.)5) Operation contents of exhibition/display mode -. All function like display, fan motor, etc operate normally, but only compressor does not operates. -. Defrost is not operated. -. Display function of initial actual temperature is finished. -. Exhibition/Display mode will be operated though Power ON after Power OFF under the exhibition/ Display mode condition.

● If the display changes to option setting mode, all displays will be off except freezer and fresh food

compartments temperature display as below. (Fresh food and freezer compartments is explained onlybecause all options are operated with the same method according to the option table.)

1) For example, if you want to change freezer compartment standard temperature to -6 (-3!) by operating option, do as following. This function is for changing the standard temperature. In -2 (-19!) of current temperature of freezer compartment, if you make the temperature lower to -6 (-3!) by the option, the standard temperature would be controlled -8(-22!). Therefore, if you changed the setting of temperature option to -2(-19!) on the panel, the appliance will beoperated with -8(-22!). It means that standard temperature is controlled -6(-3!) less than setting temperature in the display.

Basically, option function has cleared data at shipping process. Therefore, all setting value are"0". But, check the quality information manual or specifications, because setting value could bechanged particularly for the purpose of improving quality at mass producing process.

2) After changing to the option mode, fresh food compartment "0", freezer compartment "0" will be displayed. (Basically, fresh food compartment "0", freezer "0" would be set at shipping process, but

setting value could be changed for the purpose of improving quality at mass producing process.) - If fresh food compartment "0" shows only, temperature reference value of freezer compartment will be set and current freezer compartment temperature code will be displayed on the freezer temperature display.3) If freezer compartment "4" is set as below freezer compartment code after fresh food compartment "0" is set, standard temperature of freezer compartment will be lower than -6(-3!).(Refer to the picture "Changing the freezer compartment temperature")


: : If you wait for 20 seconds after completing the setting, MICOM will save the setting value to the

EEPROM and normal display will be returned and the option setting mode will be canceled.

4) Option changing method as above is the same as all LMF model.

5) Option function is set in the EEPROM at shipping process in the factory. You would better not to

change the option of your own. Completing the setting is that option function return to normal display

after 20seconds. Do not turn off the appliance before returning to the normal display mode.
