physical damage. If damage is observed, please refer to the
Service and Claims Section in the DirectVision® Technical
Reference Manual.
2. Caution: Do not use the DirectVision® System until you have
verified that it is properly assembled, setup and functioning

5. Caution: To prevent damage to the DirectVision® Guide and
camera handpiece, always handle with care. Do not drop,
crush, cut, or bend any portion of the visual guide beyond a
2” radius. Although the visual guide is flexible, bending
beyond the specified radius could cause breakage in the
fiber optic bundle, which reduces its useful life. Kinking the
visual guide could break the entire fiber optic bundle which
can render it non-operational.
6. Caution: Do not expose the DirectVision® System to
excessive heat which can cause damage.
7. Caution: Never place heavy objects on the DirectVision®
System.

The camera handpiece provides two interfaces:
• Visual Guide
• CCU
Visual Guide Interface
The camera handpiece provides alignment and a locking
mechanism for the camera handpiece-visual guide interface.
When the camera handpiece is not attached to the visual guide, a
protection cap is locked into place.

Camera Control Unit Interface
A shielded cable attached to the camera connector plug provides
the wired electrical interface between the Camera Control Unit
(CCU) and the camera handpiece. When plugging the camera
connector into the CCU, use the red dots on the camera connector
and CCU receptacle to align the recessed connector pins for
proper insertion.
Caution: Be careful how you align the Camera Handpiece Plug into
the CCU Connector Receptacle. Failure to align pins with the
corresponding pin hole could cause damage to the pins.

Storage During Transportation
When the camera handpiece is not in use,
1. The wired attached Plug Cap is locked to the Camera
Handpiece Plug. The Plug Cap protects the receded gold
connector pins.
2. Protection cap is locked into place. The cap protects the
front glass of the LED light source and camera from
accumulating dust. It also protects the outside rim of the
lock mechanism of the handpiece from damage.
3. The handpiece is stored in the cart camera holder.
