CAUTION
Please pay special attention to the following items:
1 Most cleaning agents must be diluted before use. Follow the manufacturer's directions
carefully to avoid damaging the monitor.
2 Do not use the grinding material, such as steel, wool etc.
3 Do not let the cleaning agent enter into the chassis of the system.
4 Do not leave the cleaning agents at any part of the equipment.
The monitor, cables and accessories must be kept dust-free.
Regular cleaning of the monitor shell and the screen is strongly recommended. Use only
non-caustic detergents such as soap and warm water (+40℃/+104℉ maximum) to clean the
monitor shell. Do not use strong solvents such as acetone or trichloroethylene.
Take extra care when cleaning the screen of the monitor because it is more sensitive to rough
cleaning methods than the housing. Do not permit any liquid to enter the monitor case and avoid
pouring it on the monitor while cleaning. Do not allow water or cleaning solutions to enter the
measurement connectors. Wipe around, except connector sockets.
Recommended cleaning agents are:
Tenside (dishwasher detergents) Edisonite Schnellreiniger, Alconox
Ammonias Dilution of Ammonia <3%, Window cleaner
Alcohol Ethanol 70%, Isopropanol 70%, Window cleaner
Sodium Hypochlorite 1% ~ 10%
NOTE:
1 The diluted sodium hypochlorite from 500ppm (1:100 diluted bleaching agent) to
5000ppm (1: 10 bleaching agents) is very effective. The concentration of the diluted
sodium hypochlorite depends on how many organisms (blood, mucus) on the surface
of the chassis to be cleaned.
2 The monitor and sensor surface can be cleaned with hospital-grade ethanol and dried
in air or with crisp and clean cloth.
