8. The performance of the controller may degrade if its components are exposed to severe heat. Do not use or store the unit where it will be exposed to temperatures in excess of 104°F (40°C).

1.0 INTRODUCTION It is recommended that personnel study this manual before attempting to operate, clean, service or adjust the APEX® Universal Drive System (C9800).

9. Handpieces are factory sealed. Do not disassemble or lubricate. Such attempts will invalidate the warranty.

The safe and effective use of this equipment requires understanding of and compliance with all warnings, caution notices and instructions marked on the product and included in this manual.

1.1

10. Do not insert or remove cutter blades when the handpiece motor is rotating. 11. Do not pull the handpiece cord to remove handpiece from controller. 12. After each use, thoroughly clean the unit and accessories (reference “3.1 Cleaning and Sterilizing” on page 27).

General Warnings

1. This equipment is designed for use by medical professionals completely familiar with the required techniques and instructions for use of the equipment. Read and follow all warning and caution notices and instructions marked on the product and included in this manual.

13. Equipment grounding is vital to insure safe operation. Plug the power cord into a properly earthed mains supply outlet whose voltage and frequency characteristics are compatible with those listed on the unit or in this manual. Do not use 2-prong plug adapters or 2-prong extension cords; such devices defeat the safety ground and could cause injury.

2. Do not open the controller chassis while under warranty, as this may void your warranty. There are no user-serviceable parts inside. Removing the cover may introduce an electric shock hazard by exposing you to dangerous high voltages or other risks. If the system malfunctions, return it for service immediately.

14. External equipment, that will be connected to signal input and signal output ports or other connectors, shall comply with relevant IEC standard (i.e., IEC 950 for IT equipment and IEC 601 series for medical electrical equipment). In addition, all such combinations - systems - shall comply with the standard IEC 601-1-1 (Safety requirements for medical electrical systems).

3. Prior to each use, the controller and all associated equipment must be inspected for proper operation.

Any person who connects external equipment to signal input and signal output ports or other connectors has formed a system and is therefore responsible for the system to comply with the requirements of IEC 601-1-1. If in doubt, contact a qualified technician or your local representative.

4. Do not expose the controller to moisture, operate in wet areas, or place liquids on or above the controller. Moisture can damage the unit and can create the danger of electrical shock. 5. Handle all equipment carefully. If the controller or handpiece is dropped or damaged in any way, return immediately for service.

15. Do not use the unit in the presence of flammable anesthetics, gases, disinfecting agents, cleaning solutions, or any material that is susceptible to ignition due to electrical sparking.

6. Do not block or impede the ventilation slots located on the bottom and rear of the chassis.

16. Do not attempt to use the system with incompatible equipment or accessories not authorized by Linvatec. Doing so may void any or all certifications and/or warranties.

7. Never insert foreign objects into the controller. This constitutes a safety hazard and can cause extensive damage or injury.

♦

Provides continuous internal diagnostics to monitor working conditions.

♦

Provides voice interaction messages. Contains a digital volume control to alter the volume intensity.

♦

Equipped with a user selected menu that allows the user to program and save several operating parameters and recall this particular program by user name. Holds four (4) different programs Default plus 3 Users (reference “2.3 Program Setup Menu” on page 19).

♦

Remembers current operating blade RPM settings even if the blade(s) is removed and reinserted.

♦

Accepts several optional footswitches; the APEX Multi-Function Footswitch (Cat. No. C9860), the APEX Basic Footswitch (Cat. No. C9965), the APEX Two Pedal Accelerator Footswitch (Cat. No. C9862) and the APEX One Pedal Footswitch (Cat. No. E9395).
