Since the fundus camera is a precision instrument, it is necessary to carry out daily inspection and maintenance.
To keep your KOWA
in good and safe conditions, please read this paragraph carefully.
7-1 Daily maintenance
1) After finishing photography, be sure to turn OFF the equipment and seal the objective lens with its protective
lens cap, and then lock the base. Enclose the fundus camera with the dust cover to guard against dust as well.
2) Take care that the objective lens is free of dust, fingerprints and bodily fluid like tears. Right before starting
photography for the day, make sure that the objective lens is free of dirt. If mydriatic mode is selected, you can
sufficiently check for any dirt.
3) If the main camera unit, power unit, forehead rest, a chin rest and options should be dirty, clean them with soft
cloth.
If dirt is stubborn, apply neutral detergent to clean. Do not use chemicals and solvents such as thinner and
benzene that may cause deterioration, deforming or paint peel-off.
Wipe the outer surface with soft cloth, from which water (used to moisten the cloth) was firmly squeezed
off.
Lightly wipe the monitor screen cover with soft cloth such as gauze because it is open to scar.
Wipe off the obstinate dirt with soft cloth, from which water or lukewarm water used to dilute a small
amount of neutral detergent was squeezed off.
4) If you intend not to use the camera for a long period of time, unplug from the
power outlet for safety’s sake.
• If the fundus camera in a cool room should be suddenly moved to a warmer room, or if the room in which
the camera is located should be suddenly heated, the objective lens and/or internal lens may be prohibitively
fogged. Wait for a while until the lens is defogged, and after defogging, start photography. Otherwise,
pictures taken may become out of focus.
• If it has been repeatedly fogged, the lens may get moldy. In this case, contact Kowa or Kowa dealer where
you purchased it.
Caution
Prohibitory
Do not wipe the outer surface of the instrument with solvents
such as benzene, alcohol, thinner, ether and the like. Other-
wise, such substances may cause the surface to be discolored
or deteriorated.
