AUTO SENSOR COOKING ONLY ON MODELS NE-7910 AND NE-7910C
AUTO SENSOR COOK
Step 1. Put food into oven.
NOTE | For best cooking results, be sure to wrap food in a cooking bag, cover tightly with plastic wrap or glass lid.
Step 2. Set the appropriate Auto Program by tapping Auto Sensor Control Pad until desired program appears in the display
window
Onetap......... Al Four taps........ A4
Two taps........ A2 Five taps........ A5
Three taps....... A3 Six taps... . 2.00. A6
— TOD and colon disappear. The selected Auto Program appears in the Display Window. Auto indicator light
turns on.
Step 3. Touch START pad.
— Oven !amp turns on and Auto Indicator Light begins to blink.
Turntable rotates. Microwave activity starts.
— When Auto Sensor program level disappears, a time will appear in the Display Window indicating the remainder of
the cooking time.
— When the ovens’ built in auto sensor detects steam coming out from the food, the micro-computer calculates the
balance of the cooking time. The displayed auto program indication (A2, for example) disappears and the rema-
ining cooking time automatically appears in the display window and starts to count down.
— When the time displayed counts down to 0, the beep sounds and the oven turns off automatically. Microwave
activity stops and the oven lamp and auto indicator light turn off. Turntable stops. The display window
indicates the TOD. ;
A remainder of calculated cooking time appears only with the A2 to AG settings. With A1 setting, the oven will shut
off immediately when the auto sensor detects steam from the food.
When the oven calculates the balance of cooking time to be over 60 minutes, the time will appear as hours and
minutes. )
Example: If the time should be 94 minutes, the Display Window will show 1 H 34. The seconds will not visibly count
down in the Display Window until the 34 minutes has elapsed and only 60 minutes remain. At that time the
unit will again show minutes and seconds. Seconds will now visibly count down.
1. Do not interrupt the auto sensor cooking cycle until time appears in the display window.
2. All foods must be at refrigerator temperature (38° ~ 42°F) for auto sensor cooking.
3. Before using auto sensor feature, make sure glass tray in the oven is dry to assure best auto cooking results.
4, Room temperature or heat surrounding the oven should not be above 95°F (35°C) when using the auto sensor cooking
cycle. Inaccurate cooking may result.
5. Foods less than 3 or 4 ounces should be cooked by power and time, not by the auto sensor cooking cycle.
AUTO COOK TO WARM CYCLE
Step 1. Put food into oven.
— See NOTE Under Step 1 in Auto Sensor Cooking.
Step 2. Set the appropriate Auto Program by tapping Auto Sensor Control pad.
— TOD and colon disappear. The selected Auto Program, A2 for example, appears in the Display Window. Auto
Indicator Light turns on.

Step 3. Set Warm Power by tapping Power pad 6 times.
— Auto Program indication (A2, for example) disappears. Auto Indicator Light goes off and Warm power indicator
light turns on.
Step 4. Set Warming time by tapping Time pads.
— Warming time selected appears in the display window.
Step 5. Touch Start pad.
— Warm power Indicator Light goes off and Auto Indicator Light turns on and blinks. Warming time disappears
and Auto Program (A2, for example) reappears. Oven lamp turns on. Turntable rotates. Microwave activity
begins.
— When Auto Sensor Cooking is over, Auto Indicator Light turns off, Warm power Indicator Light comes on and
blinks. Warming time appears in the display window and begins to count down.
— When warming time has elapsed the oven beeps and shuts off automatically. Microwave activity stops. Turntable
stops. Oven lamp turns off and TOD reappears in the display window.
TIME/DELAY START
TIMER This models’ digital display window can be used as a timer in the following manner:
Step 1. Set the desired time by tapping Time pads.
— TOD AND colon disappear and the selected time appears in the Display Window.
Step 2, Touch START pad.
— The time displayed simply counts down, as a digital timer would. No microwave activity begins.
Turntable does not rotate. No lights appear.
— When time has elapsed, oven beeps. TOD reappears in the Display Window.
DELAY START This oven can delay the start of any cooking function by up to 99 minutes and 99 seconds.
Step 1. Set the length of time you would like to delay the start of cooking, defrosting, or auto sensor cooking.
— TOD and colon disappear and the delay time selected appears in the Dispay Window.
Step 2, Set Power and time for Cook, or Defrost, or Select Auto Sensor Control for Auto Cooking cycle.
NOTE jIt is not possible to use the delay feature for 2 phase cooking. For example Delay-Auto Cook-Warm cycle. In other
words the three stage program cannot be accepted. ‘’E”’ indicating error will appear in the display window, if these
selections are chosen.
Step 3. Touch START pad.
— 2nd phase cooking selection disappears and the delay time reappears in the Display Window and starts to count
down. No microwave activity begins. Turntable does not rotate. No lights appear.
-— When delay time has elapsed, oven automatically enters seccnd programmed cycle.
— When cooking cycle is over, oven {amp and the power indicator light turn off. Turntable stops. TOD reappears in
the Display Window.
CHECKING PROCEDURE ON OPERATION
Instructions relating to Auto Sensor Cooking are only for NE-7910, NE-7910C.
1. If “E” indication appears in the Display Window:
You might have given wrong instruction. Touch “RESET” pad to clear and give new instructions from the beginning.
“E’’ indicating ERROR, appears under following conditions.
e When Auto Sensor Cooking is selected after Power/Time cooking is selected.
« When Auto Sensor Cooking is selected after Defrost/Time is selected.
—~9—

« When Defrost is selected after Auto Sensor Cooking is selected.
e When 3rd stage cooking is selected.
e When clock is set later than 12:59 or at impossible time like 00:73 or 83:25.

CAUTION WHEN USING
. Do not use metalware
In rare cases where you must use metal materials such as foil or skewers, etc., take care not to have the edge of the metal
material touch the inner glass screen, or the oven walls (coated steel), because the glass plate may be broken the coated
part may be burned by sparking.
Always keep the glass cooking tray clean
Do not cook foods with a high fat or sugar content directly on the glass tray.
. Do not dry clothes in the microwave oven.
. Avoid using wooden containers for more than a few seconds.
Do not operate the oven with a kitchen towel or a napkin left between the door and the front wall of the oven.
Do not press the cook button when the oven is empty.
Keep the inside of the oven clean.
Avoid cooking a small-volume of food for a long period of time.
If any visible steam or moisture is found on or around the door just wipe it off. There is no need for concern and this
never causes any microwave leakage.
Cautions when operating the control panel.
A. Do not touch contro} pads with water or oii on your finger.
When the control panel is dirty, wipe with a damp cloth first and then finish with a soft dry cloth. Do not use harsh
detergents or abrasives.
B. Do not try to touch the pads while wearing gloves or while holding any insulating materials.
C. For most accurate programming of the unit, tap the center of each pad or push the center of each button firmly.
D. Do not hit or strike the control panel since this is made of glass and may be broken.
When removing the roller-ring from. turntable for cleaning, be sure to re-install into the proper position. Avoid exposing
your watch to the magnetic-capsules located on the bottom of the turntable, or your watch may be damaged.
When power select is set at a setting other than High, the intensity of the oven lamp will vary. This is normal and
indicates that the oven is operating normally.
