FOREWORD
This Manual has been prepared to provide Sharp Service
Personnel with complete Operation and Service Information
for the Sharp Microwave Oven, R-5800A. The R-5800A is
quite similar to R-5800.
It is recommended that service personnel carefully study the
entire text of two Manuals (R-5800 and R-5800A1, so they
will be qualified to render satisfactory customer service.
.
CAUTION
MICROWAVE RADIATION
Personnel should not be exposed to the microwave energy
which may radiate from the magnetron or other microwave
generating devices if it is improperly used or connected.
All input and output microwave connections, waveguides,
flanges and gaskets must be secured.
Never operate the device without a microwave energy absorb-
ing load attached.
Never look into an open waveguide or antenna while the
device is energized.

PRODUCT DESCRIPTION
EXPLANATION OF MICROWAVE COOKING
The Sharp Counter Top Microwave Oven uses microwave Materials with a high moisture content, like most foods,
energy to produce heat in the food to be cooked. Unlike will absorb microwave energy. As the microwave energy at
conventional ovens microwave energy will cook foods a frequency of 2450 Megahertz enters the food, the
without applying external heat. molecules align themselves with the energy. Because the
microwaves are changing polarity every half cycle, the food
Microwaves, which are short electromagnetic waves of RF molecules are changing direction every half cycle or oscil-
(radio frequency) energy, pass through materials such as lating back and forth 4,900,000,000 times per second. This
glass, paper, china and most plastics. Materials such as high speed oscillation causes friction between the mole-
metal and aluminum foil tend to reflect microwaves and cules, thereby converting the microwave energy to heat.
may be used only as recommended in the cooking instruc-
tions.

LATCH SWITCH AND MONITOR SWITCH ADJUSTMENT
In case the latch switch and monitor switch do not operate
properly due to a misadjustment, the following adjustment
should be made.
1. Loosen the single (1) screw holding the latch hook to the
plate of open device.
2. With the door closed, adjust the latch hook by moving it
back and forward or up and down.
3.
4.
In and out play of the door allowed by the latch hook
should be less than 0.5mm. The vertical position of the
latch hook should be placed where the latch switch and
monitor switch have activated with the door closed.
Secure the screw with washer firmly.
Now, make sure of the latch switch operation. If the latch
switch has not activated with the door closed, loosen the
single (1) screw holding the latch hook to the plate of the
open device and adjust the latch hook position.
,S.,

: LEVER
After the adjustment, make sure of the following points:
1. The In and out play of the door remains less than 0.5 mm
Figure 1. Latch switch and Monitor
Switch Adjustment
at latched position.
First check the latch hook position, pushing and pulling
the lower portion of door toward the oven face. The result
(play of the door) should be less than 0.5 mm.
2. The latch switch interrupt the circuit before the door can
be opened.
3. The monitor switch contacts close when the door is opened.
4. Re-install the outer case and check for microwave leakage
around the door with an approved microwave survey meter.
. MICROWAVE MEASUREMENT
After the adjustment of the door interlock switches and door Recommended instruments are:
is completed individually or collectively, the following leakage NARDA 8100
test must be performed with a survey instrument and it must NARDA 8200
be confirmed that the result meets the requirements of the HOLADAY HI 1500
performance standard for microwave oven. SIMPSON 380M
REQUIREMENT
The safety switch must prevent microwave radiation emission
in excess of 5mW/cm2 at any point 5cm or more from ex-
ternal surface of the oven.
PREPARATION FOR THE TESTING:
Before beginning the actual test for leakage, proceed as
follows;
1. Make sure that the test instrument is operating normally as
specified in its instruction booklet.
Important:
Survey instruments that comply with the requirement for
instrumentation as prescribed by the performance standard
for microwave ovens must be used for testing.
2. Place the turntable tray into the oven cavity.
3. Place the load of 275 +15ml of water initially at 20*5’C in
the centre of the oven tray. The water container should be
a low form of 600ml beaker with inside diameter of
approx. 8.5cm and inade of an electrically non-conductive
material such as glass or plastic.
The placing of this standard load in the oven is important
not only to protect the oven, but also to insure that any
leakage is measured accurately.
4. Close the door and turn the oven ON with the timer set for
several minutes. If the water begins to boil before the
survey is completed, replace it with 275ml of the cool
water.
5. Move the probe slowly (not faster than 2.5cm/sec.) along
the gap.
6. The microwave radiation emission should be measured at
any point of 5cm or more from the external surface of the
oven.

FIXING PROCEDURE OF CORD ANCHORAGE
General:
Content:
T
I
L
As for the above subject, sometime it may cause to have wrong fixing about two pieces of cord anchorage
unit. But this cord anchorage is an important part for the safety, therefore it must be fixed correctly and
firmly.
1. The cord anchorage which is used to secure the mains supply cord can be fixed in two different ways.
2. If you fix them as shown in Figure 2, the mains supply cord will not be secured firmly.
3. Therefore, make sure to fix them as shown in figure 1.
