AUTO: When ON selected, the measurement results will be printed out automatically after the both eyes measurement finished (in this case, the datais cleared automatically) When OFF selected, press the print key on panel to print out the measurement results.

REFRACTOMETRY : When OFF selected, the refractometry power won’t be printed out. When STD selected, all refractometry power will be printed out. When AVG selected, only print the average value of the refractomertry power.

KERATOMETRY: When OFF selected, the keratome try power won’t be printed out. When STD selected, all keratome try power will be printed out. When AVG selected, only print the average value of the keratometry power.
EYE:When ON or OFF selected, the refractometry state diagram will be printed or not. CONCENTRATION: Set the appropriate print concentration according to different thermal printing paper.

PUPIL:When ON or OFF selected, the pupil diameter will be printed or not.

SE: When ON or OFF selected, SE data (the approximate value of cylinder power converted in to sphere power)will be printed or not. BC:When ON or OFF selected, BC(base curve of corneal contact lens)will be printed or not.

Install the Printing Paper:

1.) Pull outwards the printer cover,open the cover
2.) Place the new printer paper in the box,keep the paper head upwards
3.) Draw the paper outwardsand directly ride on the printer wheel
