(b) Make the following safety checks on all ovens to be serviced before activating the magnetron or other
microwavesource, andmake repairsasnecessary: (1)interlock operation(2) proper doorclosing, (3)
sealand sealing surfaces(arcing, wear,and other damage),(4) damage toor loosening ofhinges and
latches,(5) evidence ofdroppingor abuse.
(c) Before turning onmicrowave power for any service testor inspection within the microwave generating
compartments, check the magnetron, wave guide or transmission line, and cavity for proper alignment,
integrity,and connections.
(d) Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation
and transmission systems shall be repaired, replaced, or adjusted by procedures described in this
manualbeforethe oven is released to the owner.
(e) A microwave leakage check to verify compliance with the Federal Performance Standard should be
performedon eachoven prior torelease tothe owner.

MICROWAVE MEASUREMENT PROCEDURE
A. Requirements:
1) Microwave leakage limit (Power density limit): The power density of microwave radiation emitted by a microwave oven
shouldnotexceed1mW/cm2atanypoint5cmormorefromtheexternalsurfaceoftheoven,measuredpriortoacquisition
byapurchaser, andthereafter (throughtheuseful lifeoftheoven),5 mW/cm2atany point5cmor morefromthe external
surface of the oven.
2) Safety interlockswitches: Primaryinterlock relayanddoorsensingswitch shallprevent microwaveradiation emissionin
excessoftherequirementasabovementioned,secondaryinterlockswitchshallpreventmicrowaveradiationemissionin
excess of 5 mW/cm2at any point 5cm or more from the external surface of the oven.
B. Preparation for testing:
Before beginning the actual measurement of leakage, proceed as follows:
1) Make sure that the actual 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
microwaveovens, 21 CFR 1030.10(c)(3)(i),must be used fortesting.
2) Place the oven tray in the oven cavity.
3) Place the load of 275±15 ml (9.8 oz) of tap water initially at 20±5C (68F) in the center of the oven cavity.
Thewatercontainer shallbea lowformof 600ml(20oz)beakerwithaninsidediameterofapprox.8.5cm (3-1/2in.)and
made of an electrically nonconductive material such as glass or plastic.
Theplacing of this standardloadin the oven isimportant not only toprotect the oven, butalsoto insure that anyleakage

DESCRIPTION OF OPERATING SEQUENCE
The following is a description of component functions
duringovenoperation.
OFF CONDITION
Closing the door activates the door sensing switch and
secondary interlock switch. (In this condition, the monitor
switchcontactsare opened.)
When oven is plugged in, 120 volts A.C. is supplied to the
controlunit.(FigureO-1).
1. The display will show SHARP, SIMPLY, THE, BEST,
PRESS, CLEAR, and PRESS, CLOCK.
Toset anyprogram or setthe clock,youmust firsttouch
the STOP/CLEAR pad. The display will clear, and " : "

COOKING CONDITION
Programdesiredcookingtime touchingtheNUMBER
pads. When the START pad is touched, the following
operationsoccur:
1. The contacts of relays are closed and components
connected to the relays are turned on as follows.
(Fordetails,refertoFigure O-2)

2. 120 volts A.C. is supplied to the primary winding of the
powertransformerandisconvertedtoabout3.3voltsA.C.
output on the filament winding, and approximately 2000
volts A.C. on the high voltage winding.
3. Thefilamentwindingvoltageheatsthemagnetronfilament

circuit.
4. The microwave energy produced by the magnetron is
channelled through the waveguide into the cavity feed-
box, and then into the cavity where the food is placed to
becooked.
5. Upon completion of the cooking time, the power
transformer, oven lamp, etc. are turned off, and the
generationofmicrowaveenergyisstopped.Theovenwill
revert to the OFF condition.
6. When the door is opened during a cook cycle, monitor
switch,doorsensingswitch,primaryswitchandsecondary
switch and secondary interlock relay are activated with
thefollowingresults.Thecircuitstothe stirrermotor,the
cooling fan motor, the turntable motor, and the high
voltage components are de-energized, and the digital
read-outdisplaysthetimestillremaininginthecookcycle
whenthedoorwasopened.
7. Themonitorswitchiselectricallymonitoringtheoperation
of the primary and secondary switch and secondary
interlock relay and is mechanically associated with the
door so that it will function in the following sequence.
(1) When the door opens from a closed position, the
secondaryinterlockrelay,doorsensingswitch, primary
and secondary switch open their contacts, and then
the monitor switch contacts close.
(2) When the door is closed from the open position, the
monitor switch contacts first open, and then the
contactsof the primaryand secondary switchclose.
If the primary switch, secondary switch and secondary
interlock relay fail with their contacts closed when the door
is opened, the closing of the monitor switch contacts will
form a short circuit through the monitor fuse, secondary
switch switch, primary switch and secondary interlock
relay, causing the monitor fuse to blow.

Note:Whendefectivecomponents, the ControlUnitorKey Unitarereplaced,thedefectivepartorparts
must be properly packed for return in the shipping carton, with its cushion material, in which the
new replacement part was shipped to you.
Ifthedisplay fails to clear when the STOP/CLEAR padisdepressed, first verify the flat ribbon is making
goodcontact,verifythat thedoorsensingswitch (stopswitch)operatesproperly;thatisthecontactsare
closedwhenthedoorisclosedandopenwhenthedoorisopen.Ifthedoorsensing(stopswitch)isgood,
disconnect the flat ribbon that connects the key unit to the control unit and make sure the door sensing
switch is closed (either close the door or short the stop switch connecter). Use the key unit matrix
indicated on the control panel schematic and place a jumper wire between the pins that correspond to
the STOP/CLEAR pad making momentary contact. If the control unit responds by clearing with a beep,
the key unit is faulty and must be replaced.
If the control unit does not respond, it is
faulty and must be replaced. If a specific
pad does not respond, the above method
maybeused(afterclearingthecontrolunit)
to determine if the control unit or key pad is
at fault.
