MAINTENANCE
• When the stain is persistent:
1 Moisten a lens cleaning paper with reagent ethanol properly. Wipe the objective lens with
the lens cleaning paper by rubbing lightly.
2 If your lens cleaning paper is dirty, replace it with clean one and repeat step 1.
3 Repeat steps 1 and 2 until no stain is seen on the lens.
4 Finally, wipe the objective lens with a dry lens cleaning paper. It is o.k. to wipe the lens
after breathing on it.
Don't use the following methods because the lens can be damaged.
• Wiping the lens by grasping with fingernails
• Using a lens cleaning paper wound around a hard tool (for example, a metallic tool)
Use a soft lens cleaning paper without fiber.
• For example, BEMCOT (Asahikasei)
Don't let any strong-alkaline liquid adhere to the objective lens.
If such liquid adheres to the lens, immediately wipe it off.
If it is difficult to remove a stain from the objective lens, contact your dealer or TOPCON
(see the back cover).
