Activity

Semi-annually

Inspect rotation of lighthead / arms at all pivot points. Arms should move freely, without noise. Arms should not drift when released. Check for excessive rotation.

To clean external surfaces...

A) Clean faceplate with an antistatic acrylic cleaning solution using a soft, clean, cloth. B) Wipe external surfaces of arms / lighthead with a mild detergent and water solution. C) Rinse all surfaces with a soft cloth and clean water. D) Wipe all surfaces dry.

Faceplate

To disinfect external surfaces...

A) Apply appropriate disinfecting solution (see EQUIPMENT ALERT) to soft cloth. B) Wring excess solution from cloth, then wipe external surfaces of arms / lighthead. C) Do not rinse or dry. Allow solution to air dry.

To clean faceplate... Use an antistatic acrylic cleaning solution (ex: Brillianize) or an LCD screen cleaner (ex: Klear Screen). The solution should be free of ammonia, carbon tetrachloride, and acetone.

Sterilizing the Handle Caution

The handle is not sterile when shipped. If your application requires the handle to be sterile, it must be sterilized before use, or covered with a sterile protective barrier.

Equipment Alert

Use only steam sterilization on the handle.

To sterilize, process the handle in a dynamic air removal steam sterilizer (sterilizer that uses pressure pulses and / or vacuum purges to remove air from the chamber) at a temperature of 270° F (132° C) for four minutes minimum. If using a Midmark M9 or M11 sterilizer, use the “POUCHES” cycle. It is recommended that the handle be pouched or wrapped for sterilization to maintain its sterility until placed on the light. When pouching or wrapping the handle, use only sterilizer pouches or wraps that have been cleared by the FDA and labeled for use with the steam sterilization cycle parameters (e.g. temperature and exposure time) of the sterilization cycle being used. Place the handle on the sterilizer tray so steam can enter the opening and air and any steam condensate can drain from the handle (see illustration below).
