DO NOT BECOME EXPOSED TO RADIATION FROM THE
MICROWAVE GENERATOR OR OTHER PARTS CONDUCTING
MICROWAVE ENERGY.
IMPORTANT NOTICE
1. The following components have potentials above 250V while the
appliance is operating..
h Magnetron
h High voltage transformer (Located on Inverter (U))
h High voltage diodes (Located on Inverter (U))
h High voltage capacitors (Located on Inverter (U))
Pay special attention on these portions.
2. When the appliance is operated with the door hinges or magnetron
fixed incorrectly, the microwave leakage can reach more than
5mW/cm
2
. After repair or exchange, it is very important to check if
