Note for treatment of LCD
| Wipe the LCD carefully to prevent scratching, using tissue paper and a soft cloth. To remove dirt or salt, use a damp soft cloth, wiping slowly so as to dissolve the dirt or salt. Rinse the cloth regularly so the dirt or salt will not scratch the LCD. Do not use solvents such as thinner, acetone or benzene for cleaning. Also, do not use degreaser or antifog solution. |

Use of the proper fuse
Use of the wrong fuse can damage the equipment or cause fire.
The 1.5 A fuse (Type: FGMB 125V 1.5A PBF, Code No.: 000-157-464-10) in the fuse holder inside of the unit protects the unit from overcurrent and equipment fault. If you cannot turn on the power, check the fuse to see if it has blown. If the fuse has blown, find the reason before you replace the fuse. If the fuse blows again after the replacement, contact your dealer for advice.
