Operation of the device

Operation of the device
CAUTION - GENERAL HAZARDS
The patient should not touch the instrument with his/her hands. In
particular, the instrument should not be used as a support or an aid for
standing up.
Do not operate the device with wet hands.
CAUTION - RISK OF PINCHING
Take precautions to ensure fingers and hands are not trapped when lifting
the device.
Ensure that no parts of the body (fingers, hands) or objects are trapped
beneath the device when lowering it.
Do not place hand or fingers under the chin rest. This could result in
damage or injury.
CAUTION - RISK OF FALSE DIAGNOSIS
Avoid direct and lateral light incidence to the front of the instrument or eye
being examined. The best results will be obtained when the examination
room is slightly darkened (about 55 lux to 100 lux).
Ensure that the front lens of the objective is clean. If necessary, clean the
front lens (see section Care and cleaning, page 56). A smudged objective
may lead to incorrect measurements.
Temperature fluctuations will cause vapor condensation on the protective
glass in the measurement window and on optical parts inside the
instrument. In this case, wait about 40 min until the condensation
disappears before performing measurements.
