IMPORTANT WARNINGS
Press the vacuum footswitch (C1) The system displays the actual vacuum value in mmHg (A7).
once: vacuum is ON When a suction ring is fixated on the eye, the vacuum value
Press again the vacuum footswitch displayed must be less than 250 mmHg.
(C1): vacuum is OFF If the value displayed is above 250 mmHg, please refer to chapter

tone charged (>90%)
Control unit runs on battery

step: fast forward speed, with a louder tone than with 2
Intervention
The system runs automatically on the backup battery: check LED
A11 is OFF.
At the end of the surgery case, connect the console to the main
power supply to recharge the battery immediately: check LED A11
is ON.
Connect the console to the main power supply to recharge the
battery immediately.

If the vacuum cannot be interrupted by pressing the vacuum footpedal while suction ring is on patient's eye,
cut or disconnect the vacuum tubing from the console to decrease pressure.
Then lift keratome carefully taking care not to harm the corneal hinge.

XI. CARE & MAINTENANCE
In cases of unusual vibrations or noises, instability, unusual performance, or failure to pass the vacuum test,
do not use the unit and contact MORIA or your distributor for servicing.
MORIA strongly recommends having the system thoroughly inspected by MORIA on a routine basis
every year.
To clean the control unit, use isopropyl alcohol on a cloth; do not use solvents, abrasives, fluids, or solutions
on the control unit and footpedals.
Please contact MORIA for any other servicing.

Note: Even if there is a vacuum loss during the case, the
microkeratome will continue to function.
Reason Intervention
Loss of turbine pressure The red LED will turn ON (as soon as the pressure is below 2.5
bars).
At the end of the case, check the system and run a test procedure.
Note: The loss of turbine pressure will decrease the blade
oscillation rate.
Too much turbine pressure If the pressure going in the console exceeds 8 bars (116 psi), it
may damage the unit. MORIA strongly recommends sending back
the console for a complete check-up. The pressure sensor board
and other components may have been damaged and may alter
the performance of the turbines and/or alter the information on the
display panel.
