WARNING - RISK OF ELECTRIC SHOCK
Prevent moisture from penetrating the instrument or keyboard. Disconnect
the power cable from the power supply before cleaning or disinfecting the
device.
CAUTION - RISK DUE TO CROSS-CONTAMINATION
Parts with which the patient has come into contact during the examination
(chin rest, forehead rest) should be cleaned with a disinfectant approved for
the purpose. These parts are resistant to cleaning agents categorized as
"low" (e.g. suds, quaternary ammonium compounds) and "intermediate"
(e.g. alcohol, Javel water, iodine); classification pursuant to: Disinfectants
and activity spectrum according to the Center of Disease Control and
Prevention, Atlanta, USA.
CAUTION - RISK OF FALSE DIAGNOSIS
Use the supplied dust cover to protect the device against dust when not in
use.
CAUTION - PROPERTY DAMAGE
The national disinfecting regulations must be observed in the choice of
disinfectants and methods. Please note that some cleaning agents and
disinfectants may have an adverse effect on plastic components. Damage
caused by such disinfectants is not covered by our warranty. The surfaces of
the instrument have been tested to withstand frequent and long-term
treatment with alcoholic disinfectants and cleaning agents.
Never use aggressive or abrasive cleaning agents.
Cleaning of optical components
The multilayer T* (T-star) antireflection coating of the optical components
(e.g. eyepieces and objectives) results in excellent image quality.
Even slight contamination of the optics or a fingerprint will impair image
quality. In order to protect the internal optical elements from dust, never
leave the device without the objective, binocular tube or eyepiece attached.
After use, cover the device to protect it from dust. Always store objectives,
eyepieces and accessories that are not being used in dust-free cases.
