Maintenance
◆ Regular care
Be sure to disconnect the power cable before doing any maintenance.
<Main unit>
Wipe with a soft cloth. Use a damp cloth with a mild detergent and then wipe with a dry cloth again if the unit is heavily soiled. Do not use
strong solvents such as thinner or alcohol as they may damage the unit casing.
<Lens>
Use commercially available blowers or lens tissue to remove any dirt from the lens.
<Filter>
If dust accumulates on the ventilation port filter, the internal temperature of the unit rises, which may cause damage to the unit. Clean the
filter approximately once every 200 hours. Remove the power cable from the AC outlet, and remove dust from the filter with a vacuum
cleaner.
To prevent dust from entering the filter itself, be sure to vacuum the filter with the unit on its side.
◆ Replacing the filter
Replace the filter when it becomes difficult to remove dust from it.
Maintenance
1. Turn off the power and remove the power cable.
2. Carefully place the unit upside down on a soft cloth to prevent scratching.
3. Press the filter hook on the underside of the main unit to remove the filter.
4. Firmly attach the new filter. The lamp does not light if the filter is
incorrectly attached.
Warning
• Contact a YAMAHA dealer or service center if you require replacement filters.
