MACHIDA
Operating / Service Manual
Functions:
Eyepiece
Lens system used to enlarge and image the object in view. When looking through the eyepiece, a “V”-shaped
pointer can be seen. This pointer indicates the “up” side of the scope and aids in the orientation of the viewed
object.
Focus Adjustment Ring
Focus adjustment ring which moves the eyepiece in and out to allow for a clear, focused image. Alignment of
colored dot (on ocular) and colored line (on focus ring) put scope at infinity focus.
Angle Deflection Knob
Knob that controls the direction and degree of deflection at the distal end. Turning this dial in either the “U”
(up) or “D” (down) direction will cause the tip of the scope to be deflected up or down respectively.
Angle Lock/Brake Lever
Cam action lever which engages the brake. Turning this lever to “E” (engage) will cause the deflection to be
fixed at any desired position. When the lever is moved to “F” (free), the deflection will no longer be fixed and
the scope will return to the straight (at rest) position.
Main Body
Plastic housing containing internal components. Sealed to withstand soaking.
Insertion Tube
Flexible protective tubing containing angle controlling wires, fiberoptic image guide and light guide. This part is
inserted into the patient’s nasal cavity.
Angle Deflecting Section
Flexible portion of the scope which articulates when the angle deflection knob is rotated.
DEVICE OPERATION - Functions
All scopes are delicate instruments. Never
forcefully twist, pull or bend the insertion tube
and avoid excessive shock.

CAUTION
