#1 How often should the microwave oven be cleaned to maintain its condition?
The oven should be cleaned regularly, and any food deposits should be removed to prevent deterioration of the surface, which could adversely affect the life of the unit (Page 8).
#2 What should I do if the microwave displays an 'E03' error code?
If the system enters super high temperature protection status, the display will show 'E03' and continue to beep. Pressing the STOP/CANCEL button will return the system to normal standby mode (Page 17).
#3 What is the procedure for replacing the light bulb in the microwave?
If the light bulb burns out, please contact customer service to have it replaced (Page 8).
