DO NOT operate on a 2-wire extension cord during
repair and use.
NEVER TOUCH any oven components or wiring
during operation .
BEFORE TOUCHING any parts of the oven, always
remove the power plug from the outlet.
For about 30 seconds after the oven stop, an electric
charge remains on the high voltage capacitor. When
replacing or checking, you must discharge the
capacitor by shorting across the two terminals with an
insulated screwdriver.
Remove your watches whenever working close to or
replacing the Magnetron.
NEVER operate the oven with no load.
NEVER damage the door seal or front plate of the
oven cavity.
NEVER put iron tools on the magnetron.
NEVER put anything into the latch hole and the
interlock switches area.
Proper operation of the microwave oven requires that
the magnetron be assembled to the waveguide and
cavity. Never operate the magnetron unless it is
properly installed.
Be sure that the magnetron gasket is properly installed
around the dome of the tube whenever installing the
magnetron .

high-voltage and high-current appliance.
Though it is free from danger in ordinary use,
extreme care should be taken during repair.

energy which may radiate from the magnetron or
other microwave generating device if it is
improperly used or connected.
All input and output microwave connections,
waveguide,flange and gasket must be secure
never operate the device without a microwave
energy absorbing load attached.
Never look into an open waveguide or antenna
while the device is energized.

Installing microwave oven
1. Empty the microwave oven and clean inside it with a
soft, damp cloth. Check for damage such as
misaligned door, damage around the door or dents
inside the cavity or on the exterior.
2. Put the oven on a counter, table or shelf that is
strong enough to hold the oven, food and utensils
you put in it. (The control panel side of the oven is
the heavy side. Use care when handling.)
3. Do not block the vent and the air intake openings.
Blocking vent or air intake openings can cause
damage to the oven and poor cooking results.
Make sure the microwave oven legs are in place to 
ensure proper air flow.
4. The oven should not be installed in any area where
heat and steam are generated, because they may
damage the electronic or mechanical parts of the
unit.
Do not install the oven next to a conventional
surface unit or above a conventional wall oven.
5. Use the microwave oven in an ambient temperature
of less than 104¡F (40¡C).
6. Place the microwave oven on a sturdy and flat
surface, at least 10cm(4 inches) from the wall.
7. Place the microwave oven as far away as possible
from TV, RADIO, COMPUTER etc, to prevent
interference.
8. This oven must be plugged into a 15A outlet.

of the Grill, Convection and Combination mode.
This glass is very hot during heater operating.

mode with the Convection rack or Grill rack placed
