may introduce an electric shock hazard by exposing you to dangerously high
voltages or other risks. If the system malfunctions, return it for servicing
immediately.
16. Misuse may damage the AR-200 and may cause risks and hazards for
patients, users and third parties.
17. Misuse, as well as unauthorized assembly and modifications or repairs to the
AR-200 system, or non-compliance with our instructions relieves us of all
liability for claims under warranty or other claims.
18. Use only Arthrex approved accessories.Other accessories may result in
increased emissions or decreased immunity of the system. Contact your

WARNING!
The console, the motors with cable and the footswitch are not suitable for use in
potentially explosive atmospheres or with potentially explosive mixtures of
anesthetic substances containing oxygen or nitrous oxide. Zone M is defined as
a ”medical environment“ and constitutes the part of a room in which potentially
explosive atmospheres may form, due to the use of anesthetics or medical
antiseptics and antibacterial soaps; such atmospheres are typically localized and
temporary. Zone M comprises a truncated pyramid below the operating table
which is tilted outwards at a 30° angle.
WARNING!
Zone G, also known as an ”enclosed medical gas system“, does not necessarily
include areas enclosed around all sides, in which explosive mixtures are
continuously or temporarily generated, directed or used in small quantities.
Do not disconnect the plug of the foot pedal unit by pulling on the
cable. Remove the foot control plug by grasping and pulling on the
body of the connector.
Position the foot control unit, where it cannot be unintentionally
pushed.
Foot control: The foot control is approved for use in zone M (AP).
Regular checking of the foot control:
- Visual inspection for outside damage
- Visually inspect the ESD spring contact on the underside of the foot control
(electrostatic discharge)
- Clean and inspect the ESD spring contact on the underside of the foot control
on a regular basis.
