Chapter 3 Preparation and inspection before observation
• When removing the insertion tube from the drum, do not apply excessive force. Otherwise,
the insertion tube may be damaged.
• When taking the control unit or base unit out of the case, never hold them by the scope
(including the bend stopper), universal cable, LCD cable or LCD monitor. It may damage the
instrument.
• Check if the gaskets of scope unit, battery cover, I/F connector cover, slot cover, AC adapter
cover, and base unit are kept clean. Wipe off with a clean, soft cloth if dirt or a foreign
substance is attached.
• Check the gaskets of scope unit, battery cover, I/F connector cover, slot cover, AC adapter
cover, and base unit if cuts or gaps are not available.
• Make sure that the scope unit is attached to the base unit firmly.
