Safety Information
WARNING: Do NOT block the ventilation openings. These allow
for the release of heat generated during operation. A buildup of
heat due to ventilation opening blockage can cause failures
which may result in a fire hazard.
WARNING: To prevent electric shock, the instrument must be
plugged into an earth grounded outlet. Do not remove or
disable the ground pin. Only an authorized Carl Zeiss Meditec
service representative may install the instrument.
WARNING: Do not use the printer or the instrument or the
power table with an extension cord or a power strip (multiple
portable socket outlet). For additional safety, do not plug the
printer and the instrument (or the power table) into the same
wall outlet. Failure to observe this warning could result in
electrical shock to the patient and/or examiner.
WARNING: Do not open the instrument covers. Opening the
instrument covers could expose you to electrical and optical
hazards.
