Maintenance
• Stains on the cabinet
Should be wiped off with a soft cloth. If the cabinet is heavily stained, wipe it with a cloth soaked in water-diluted neutral
detergent and wrung well, then wipe clean with a dry cloth.
• Since the cabinet may deteriorate in quality, become damaged or get its paint peeled off, be careful about the following:
– Do not wipe it with a hard cloth.
– Do not wipe it strong.
– Do not wipe it with thinner or benzene.
– Do not apply any volatile substance such as insecticides to it.
– Do not allow any rubber or vinyl article to remain in contact with it for a long time.
• Stains on the lens
Sould be cleaned off with commercially available blowers or lens cleaning paper (for cleaning glasses and cameras).
Do not use liquid cleaning agents. This could cause the surface coating to be removed.
Do not rub or hit the lens as its surface is prone to damage.
