BX40F E. REPAIR PROCEDURE
1, OPTICS CLEANING
1-1 Precautions
Dust is not seen through the eyepiece at observation, because it is
not focused. But, if the dust is stacked, it will affect the observa-
tion brightness and the color temperature in photomicrography. So,
take precautions to keep your finger away from the optical parts and to
prevent exudation of grease. Illuminate with the maximum lamp
voltage to facilitate checking a finger-print and exudation of grease.
