@ Doneness Control Pads: (NE-9970, NE-9970C only)
Preferences for food doneness vary with each individual. After having used the Auto
Sensor
Cycles
a
few
times,
you
may
decide
you
would
prefer
your
food
cooked
to
a
different doneness. By using the Doneness Control, the Auto Sensor programs can be
adjusted to cook food for a longer or shorter time.
Note: If you are satisfied with the result of cooking with the built-in Auto Sensor program,
you do not need to use these pads.
More Pad:
Use when you want your food to be cooked a little more than the built-in auto program.
Less Pad:
Use when you want your food to be cooked a little less than the built-in auto program.
@ Stop/Reset Pad:
Before cooking: One tap clears your instructions.
During cooking: One tap temporarily stops the cooking process. Another tap cancels all
your instructions and time of day appears in display window.
@® Start Pad:
One tap allows oven to begin functioning. If door is opened or Stop/Reset Pad is tapped
once during oven operation, Start Pad must be touched again to restart oven.
@® Display Window:

Microwave cooking lets you defrost foods quickly, prepare delicious stews, savory casseroles, and vegetables that
come out tender and colorful. It’s also an ideal and easy way to reheat leftovers that taste as though they were freshly
Prepared.
Note: 1) See cooking utensils section in your Panasonic Cookbook or page 11 or this manual.
2) Do not use recycled paper products in the oven. They may contain impurities which could cause the paper to
create sparking (arcing), and this could result in a fire during oven operation.
3) Do not operate oven empty.
Auto Sensor Cooking (NE-9970, NE-9970C only)
Auto Sensor Cooking allows you to cook most of your favorite foods without having to select cooking times and
powers. The oven does it all automatically.
For proper cooking results on Auto Sensor cycles, be sure to cover foods securely with plastic wrap or place foods ina
microwavesafe casserole dish with a proper fitting lid.

NOTES ON AUTO SENSOR COOKING:
The Auto Sensor system works by detecting a build-up of steam on the humidity sensor. As foods cook in the
microwave, steam is produced. When foods are covered, the steam will build up and escape from the dish ina
burst. This burst of steam is detected by the humidity sensor and then the oven automatically calculates the
remaining cooking time.
When an Auto Sensor Cycle is selected, Cook A1 through A8 will appear in the display window. The oven door
should not be opened for longer than one minute when Cook A1 through A8 appears in the display window.
Opening
the
door
may
cause
inaccurate
cooking
results.
Once
the
steam
is
detected,
the
remaining
cooking
time
immediatety
appears
in
the
display
window
and
begins
to
count
down.
At
this
time,
the
oven
door
may
be
opened,
to stir, turn or add foods. On Cook A1, no time will appear in display window.
@Auto Sensor Cooking is successful with the foods and recipes.found in the cookbook and marked with the
Symbol[A],
Because
of
the
vast
differences
in
food
composition,
recipes
and
charts
without
the
Auto
Sensor
symbol should be prepared in your microwave oven using the Power and Time features.
When cooking by Auto Sensor, the oven door should not be opened for longer than 1 minute while Cook A1—A8
is in display window. Opening the door for longer than 1 minute may cause inaccurate cooking results. Once
time appears in display window, the door may be opened and foods can be stirred or turned.
®All foods for Auto Sensor Cooking are taken from their normal storage place.
Before
using
Auto
Sensor
feature,
make
sure
glass
ceramic
tumtable
in
the
oven
is
dry
to
assure
best
Auto
Sensor
Cooking
results.
Room temperature of heat surrounding the oven should not be above 95°F when using Auto Sensor Cooking
feature. Inaccurate cooking may result.
Foods less than 3 or 4 ounces should be cooked by Power and Time features, not by the Auto Sensor Cooking
Cycle.
The
appropriate
food
categories
for
each
Auto
Sensor
Cycle
are
as
follows.
For
further
information,
refer
to Introduction and Auto Sensor recipes in the Panasonic Cookbook.
Canned Foods, Leftovers, Noodles Beans, Cauliflower, Peas
Chicken Pieces Fish, Broccoli
Stews Frozen Hamburgers
Potato, Carrot Frozen Chicken Pieces
When the remaining cooking time is over 60 minutes the time will appear as hours and minutes.
Example: If the cooking time is 94 minutes, display window will shaw 1H34. The seconds
will not visibly count down in display window until 59 minutes remain. The time in
display window will then show in minutes and seconds, and count down in
seconds.
Preferences for food doneness vary with each individual.
After having used the Auto Sensor Cycles a few times, you may decide you would prefer your food cooked to a
different
doneness.
By
using
the
Doneness
Controi
Pads,
the
Auto
Sensor
programs
can
be
adjusted
to
cook
food for a longer or shorter time.
Note:
“If

DESCRIPTION OF OPERATING SEQUENCE
1. Variable power cooking control
The coil of power relay C is energized intermittently by the digital
programmer circuit, when the oven is set at any power selection ex-
cept for High power position. The digital programmer circuit controls
the ON-OFF time of power relay C contacts in order to vary the output
power of the microwave oven from “Warm” to “High” power.
One complete ON and OFF cycle of power relay C is 22 seconds.
The relation between indications on the control panel and the output
of the microwave oven is as shown in Fig. 5.
NOTE: The ON/OFF time ratio does not correspond with the percen-
tage of microwave power since approximately 2 seconds are
required for heating of magnetron filament
2. Cyclic defrost
When Defrost power and defrosting time is selected and Start pad is
tapped:
(A)
The
digital
programmer
circuit
(DPC)
divides
the
total
defrosting
time
into
8
cycles
of
alternating
ON-OFF
intervals
of
defrosting
power
and
standing
periods.
(See
Fig.
6)
(B) During each defrosting period, power relay C is energized for 9
seconds and de-energized for 13 seconds by DPC. (See Fig. 7)
(C) During standing periods, power relay C is always open resulting in no
microwave power. ae
NOTE: Defrost time selected is converted into seconds by the DPC but
display will show selected time in minutes and seconds as prog-
rammed. The total number of seconds is divided Into 8 time
periods. The remainder (seconds not equally divisible by 8) are
added to the last standing time period.
Example 1: If defrosting time is selected for 2 minutes 56 seconds, each
operating period will be as follows : (See Fig. 8)
2 minutes 56 seconds = 176 seconds
176/8 = 22
Example 2: If defrosting time is selected for 5 minutes, each operating
period will be as follows : (See Fig. 9)
5 minutes = 300 seconds
300/8 = 37 and remainder is 4 seconds.
The 4 seconds is added to the last time period.
NOTE: When defrosting time is selected for not more than 7 seconds,
the power relay C will not be energized at all.

Convection
cooking
control
The
digital
programmer
circuit
controls
the
ON-OFF
time
of
the
heater
in
order
to
control
oven
cavity
temperature.
(A)
After
the
start
pad
is
tapped
with
the
desired
convection
program
set,
an
18V
DC
signal
comes
out
of
the
digital
programmer
circuit
and
is
applied
to
coil
of
power
relay
B.
(B)
When
the
contacts
of
power
relay
B
close,
power
source
voltage
(120V
AC)
is
applied
to
the
heater
and
the
heater
turns
on.
(C)
When
the
oven
temperature
reaches
the
set
temperature,
the
digital
programmer
circuit
senses
the
temperature
through
oven
temp
sen-
sor
and
stops
supplying
an
18V
DC
signal
to
the
coil
of
power
relay
B
and
the
heater
turns
off.
(D)
After
the
heater
turns
off,
the
oven
temperature
will
continue
increas-
ing
a
while
and
then
decrease
as
shown
in
Fig.
12.
When
the
oven
temperature
drops
below
the
set
temperature,
the
digital
programmer
circuit
senses
the
signal
and
starts
supplying
an
18V
DC
signal
to
the
coil
of
power
relay
again.

Combination
cooking
control
Combination
cooking
is
accomplished
by
microwave
and
convection
cooking
being
done
alternately
during
one
combination
cooking
cycle.
One
combination
cooking
cycle
is
22
seconds.
(A)
During
combination
cooking,
the
digital
programmer
circuit
controls
ON-OFF
time
of
both
power
relay
B
and
C
as
shown
in
Fig.
14.
(B)
When
the
power
relay
C
is
turned

heater
turns
off
and
after
the
power
relay
C
tums
off,
power
relay
B
tums
on.
NOTE
1:
Note
that
the
heater
may
not
be
on
during
a
heater
on
period
if
the
preprogrammed
oven
temperature
has
been
reached.
This
is
due
to
the
fact
that
the
oven
is
keeping
the
preprogrammed
oven
temperature
constant,
so
of
course
the
heater
will
only
be
on
when
It
is
needed
and
off
when
it
is
not
needed.
(See
Fig.
14)

2:
As
for

cooking
for
convection,
the
