Tools normally used for TV servicing are sufficient.
Standard tools are listed below.

• Diagonal pliers
• Long nose pliers
• Cross head screwdriver
• Wrench (size 5 mm)
• Nutdriver (size 5 mm)
• Adjustable wrench
• Soldering iron
• Solder
• Vinyl insulation tape
• Polishing cloth

• Be sure to check a microwave emission prior to

servicing the oven if the oven is operative prior to
servicing.

• If the oven operates with door open, the service

personnel should;
—Tell the user not to operate the oven

• The service personnel should check all surface and

vent openings for microwave emission testing.

• Check for microwave energy leakage after every

servicing. The power density of the microwave
radiation leakage emitted by the microwave oven
should not exceed 4 mW/cm

2

.

And always start measuring of an unknown field to
assure safety for operating personnel from radiation
leakage.

NOTE: The standard is 5 mW/cm

while in the

customer’s home. 4 mW/cm

stated here is

manufacturer’s own voluntary standard for units in
customer’s home.

• Microwave Survey Meter
• 600cc glass beaker
• Glass thermometer 100°C

• TESTER (VOLTS-DC, AC, Multmeter)
• Microwave survey meter

—Holaday H1-1500, Hi-1501
—Narda 8100, 8200

• Inch scale
• 600 cc non conductive material beaker (glass or

plastic), inside diameter: approx. 8.5cm (3

in.)

•  Cylindrical and made of borosilicate glass vessel max.

thickness: 3mm
outside diameter: approx. 190mm
height: approx. 90mm

•  Glass thermometer: 100°C or 212°F (1 deg scale)

• Pour 275 ± 15cc of 20°C ± 5°C water in a beaker which

is graduated to 600 cc, and place the beaker on the
center of the turntable.

• Set the energy leakage monitor to 2,450 MHz and use

it following the manufacturer’s recommended test
procedure to assure correct result.

• When measuring the leakage, always use the 2 inch

(5cm) spacer supplied with the probe.

• Operate the oven at its maximum output.
• Measure the microwave radiation using and

electromagnetic radiation monitor by holding the probe
perpendicular to the surface being measured.
