The objective lens in the Videoscope is fixed and cannot be adjusted. An object will be in focus if it is between
1.0 inch and infinity.

RTICULATION
CAUTION
:
Do not attempt to articulate Videoscope in the coiled state, catastrophic failure to the
articulation system will occur from added stresses placed on the system. The working length of the
instrument should be in the elongated state at-all-times when articulating the instrument.
The Videoscope has four-way articulation (up, down, left and right). The knobs on the handpiece control the
articulation, see Fig. 5. Rotate one knob to articulate up/down, and rotate the second knob to articulate left/right.
The Videoscope articulation system is considered at its “neutral position” when the distal end is lying in line with
the working length. When neutral, the neutral dots on the Articulation Knobs should be in line with each other
and the white neutral indicator line on the rear body housing.
The scope should always be returned to this
position prior to withdrawal from area being viewed.

Once an object has been acquired in the field of view, line of sight may be maintained by using articulation
locks. Locks are oval rocking levers located to the side of knobs. Each knob has its own color-coded lock to
switch on or off.
When “ON”, the ratchet style locking system engages, while the “OFF” position allows Videoscope to articulate
freely. The ratchet system holds the line of sight. It can also be overpowered by turning the knob to the next
locking position. The operator will hear an audible click as the knob is advanced from position to position. This
is the ratchet mechanism at work.
CAUTION:
Always unlock and straighten Videoscope before withdrawal. Failure to do so may result
in catastrophic failure. Scope is straight when the knobs are returned to their neutral position.
