SAFETY PRECAUTIONS NN-G61 AR
CAUTIONS TO BE OBSERVED WHEN
TROUBLESHOOTING
Unlike many other appliances, the microwave oven is high-
voltage, high-current equipment. Though it is
free from danger in ordinary use, extreme care should be
taken during repair.
Check the grounding
Do not operate on a 2-wire extension cord. The microwave
oven is designed to be used when grounded.
It is imperative, therefore, to make sure it is grounded prop-
erly before beginning repair work.
Warning about the electric charge in the high voltage
capacitor
For about 30 seconds after the oven is turned off, an elec-
tric charge remains in the high voltage capacitor.
When replacing or checking parts, turn the oven off, wait
30 seconds and short the terminal of the high voltage ca-
pacitor (terminal of lead wire from diode) to chassis ground
with an insulated handle screwdriver or an insulated jumper
lead wire to discharge.
When parts must be replaced, remove the power plug
from the outlet.
Avoid inserting nails, wire, etc. through any holes in
the unit during operation.
Never insert a wire, nail or any other metal objects through
the lamp holes on the cavity or any other holes or gaps,
because such objects may work as an antenna and cause
microwave leakage.

CONFIRM AFTER REPAIR

After repair or replacement of parts, make sure that the
screws of the oven, etc. are neither loose nor missing. Mi-
crowaves might leak if screws are not properly tightened.
1. Make sure that all electrical connections are tight before
inserting the plug into the wall outlet.
2. The special connection cable used for connection of this
apparate may be replaced only by qualified service-per-
sonnel using a special cable, which can be obtained only
from the Panasonic -Service. (Refer to Parts List).
CAUTION
Servicemen should remove their watches whenever
working close to or replacing magnetron.
WARNING
Never touch any circuit wiring your hand nor even with an
insulated tool during operation
Important Note
1. High voltage above 250V are existing on following parts
during operation.
 Magnetron
 High voltage transformer
 High voltage Diode
 High voltage Capacitor
Unusual attention should be paid during repair or
troubleshooting of product.
2. If the microwave oven is operated with incorrect installed
door hinge or magnetron, it can cause microwave leak-
age of over 5mW/cm2.
Hence it is absolutely necessary to check if magnetron
and door hinge are correctly and safely intalled after
repair or replacement.
CAUTION
MICROWAVE RADIATION
Personnel should not be exposed to the microwave energy
which may radiate from the magnetron or other microwave
generating device it is improperly used or connected all
input and output microwave connection waveguides,
flanges, and gasket must be secure. Never operate the
device without a microwave energy absorbing load
attached. Never look into an open waveguide or antena
while the device is energized.
