Frame Only.
1. After taking all the accessories out of the microwave oven, turn the microwave oven over on its
back and keep the base of the microwave oven facing towards you.
2. Remove the adjustable feet (Fig. No. 2) from the plastic bag and screw them into the holders
(Fig. No. 1), one by one.
3. Once all 4 feet are fitted, turn the microwave oven back over onto its feet to check if the adjust-
able feet are level. If the microwave oven is unstable, adjust the feet by screwing them up or down
accordingly.
