Features
3.Features
3.1 Safe to use
The door adopts unique anti-choke structure and integrated punch forming, and thus
effectively prevents the microwave from leaking.
It is controlled by two-step interlock switch. The power will be switched off automatically
when the door is open, therefore it is much safer to use.
3.2 Shining appearance
The door shell and operation panel frame shell adopt in ported high-quality stainless
steel material, and will never get rust and change color. It has modern appearance and
superior quality, and thus becomes the best choice for the household microwave oven.

POINTS OF ATTENTION
Not like the other household appliances, the microwave oven is a kind of
high-voltage appliance. Although common operations will not risk the user in
hazard, please operate it carefully.
1. Do not use duplex receptacle in usage and maintenance.
2. Do not touch any components and circuit when the microwave is running.
3. Be sure to switch off the power before you touch the inside structure of the oven.
4. The high-voltage capacitor may still maintain electricity even 30 seconds after the
microwave oven stops working. To make replacement or checking at this time, be sure
to use insulated screwdriver to short out the two ends of the capacitor and discharge
the stored electricity.
5. Prevent the wristwatch from touching the microwave oven.
