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

correctly.

3. Caution: Use only in conjunction with other Type BF or CF

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.

DirectVision®Technical Reference Manual

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.

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.
