6.3 LIGHT INTENSITY CONTROL AND DISPLAY
The light intensity is adjustable enabling the user to obtain a brighter or dimmer output by pressing and
holding or repeatedly pressing the up or down arrow buttons until the desired illumination is reached.
Each momentary press changes the intensity 5%.
There is an illuminated vertical bar graph LCD display for visual reference to the amount of light
intensity. Each fully lit segment represents 10% of the available intensity.
6.4 DATA PORTS
There are three (3) DATA Transfer Ports; USB Type 'A', USB Type 'B' and a Serial Port located on the
rear of the cabinet to allow communications between the lightsource and other monitoring or controlling
equipment.
For technical information concerning the DATA Ports or assistance please contact Customer Service.
7. CLEANING AND DISINFECTION
7.1 CLEANING AND DISINFECTING THE UNIT
NOTE
Always disconnect the power cord before cleaning and while unit is drying if wet- wiped
if wet-wiped.
Cleaning and disinfection agents should be commercially available cleansers commonly used for
cleaning and/or disinfection of electronic equipment cabinents in hospitals, such as ethyl or isopropyl
alcohols, disinfecting sprays containing quaternary ammonium compounds or hydrogen peroxide.
7.2 CLEANING THE OPTICS
Exercising proper care for the glass optic in your LED 4000 lightsource can help maintain light quality
and extend usable lifetime. Using the proper cleaning products and methods are as important as
cleaning the component itself.
Cleaning Solutions
There are a variety of cleaning solutions you can use such as Reagent-Grade Isopropyl Alcohol,
Reagent-Grade Acetone and De-Ionized Water to ensure a long product lifetime. A good solvent mix
to use is a mix of 60% acetone* and 40% methanol. (Acetone alone dries too quickly to dissolve all of
the debris. The methanol slows the evaporation time, and also dissolves debris that acetone alone
would not clean.)
*Acetone should never be used on plastic optics or components as it will damage them.
Optic Cleaning Procedure
Step #1
First use compressed air (aerosol can) to remove surface dust without directly contacting any coating
the optic may have. (Wiping a dusty optic with cotton swabs or lens paper can abrade and damage
the optic.)
Step #2
Soak with solvent a Cotton-Tipped Swabs or Lens Tissue then use a circular motion starting from the
edge of the optic moving towards the center to wipe away any dust or dirt. Repeat as necessary, each
time use a new cotton swab or lens tissue.
