Fuse replacement
The fuse in the fuse holder protects the equipment from internal fault. If the fuse blows, find the cause before replacing it. If the fuse blows again after replacement, request service.
WARNING
Use the proper fuse.
Use of a wrong fuse can cause fire or damage to the equipment.

Battery replacement
The remote controller has two AA batteries. If the distance from which the remote controller can be operated has decreased, change the batteries.
Note: Use the two AA batteries. Replace all batteries together. Do not mix old and new batteries.
WARNING
Ensure battery polarity is correct.
Wrong polarity may cause the batteries to explode.
Dispose of used batteries as industrial waste. Follow the appropriate regulations for the disposal of industrial waste.
LCD replacement
The life of the LCD is about 40,000 hours. When the brilliance cannot be raised sufficiently, replace the LCD.
