forehead pressed firmly against the head rest.
4. Select the laser treatment spot diameter, exposure time and beginning
treatment power level.

6. Select READY mode. The aiming beam will turn on.
7. Adjust the aiming beam intensity.

placement of the laser beam with the slit lamp joystick or micromanipulator.

NOTE
Always place the system in STANDBY mode if there is a prolonged pause in treatment.
If the system is in READY mode and remains idle for 5 minutes, it automatically
reverts to STANDBY mode. To resume treatment, place the system back into READY
mode.
If the system remains idle for 30 minutes, it will END the current treatment and return
all parameters to the default position. The pulse count will retain the same pulse count
of the prior treatment and can only be reset by pressing the Reset button on the
