from 0.01 to 3.0s by using the press action switches located directly below the Repeat
Interval display. If the duration is adjusted beyond 3.0 seconds, the “Pulse Duration”
display will show “CW” and the laser output will be continuous for as long as the foot
switch is pressed down. If the interval is adjusted beyond 3.0 seconds, the “Repeat
Interval” display will show “One” and the foot switch will need to be pressed every time
the doctor wishes to fire the laser.
By default setting or when the laser is powered on for the first time, the pulse duration is
0.02 seconds and the repeat interval is set to “One”. The laser output power is set to
0mW. These initial values can be changed by selecting the desired settings and by using
the saving function button on the screen and key in the customized name. You may
retrieve this setting by reopen the file folder.
Inside the Laser System there are two shutter modules that completely blocks the beam
path at all times except when the system is in the READY mode and footswitch is
activated. The microprocessor constantly monitors the electronic sensors position and
their integrity of the shutter at all times. Whenever the system boots up, it will check for
the shutter position to validate if the shutter is engaged and functioned.
The shutter remains closed until doctor initialized the READY mode. This ensures that
the patient is protected in the case of a misfire. When the footswitch is pressed the
microprocessor will carry out various checks on the status of the laser system including
the correct position of the shutter. After the microprocessor finishes the system
checking, then the shutter will await to be opened or activated. If this is OK then the
Laser Diode will be turned on for the selected pulse duration. There is a closed loop
control system to ensure a stable output pulse. The footswitch must be released in order
for next requested to be operated again. The position of the shutter will continuously be
checked during all operating modes.
A sum of the total delivered Laser pulses is shown on the LCD Control panel located near
the bottom right. A reset button switch is located next to the display button. You may
clear the setting by pressing this button will reset the value.
In the case of an emergency, the Red Emergency Switch can be pushed in and locked
down to cut off all power. Normally power can be turned off by using the key switch. In
order to prevent unauthorized persons from operating the system, the key should not be
left in the keyhole when the Laser System is not in use.
The software shutdown is must be clear first prior to turn off the console. The red
power down indicator on the left bottom of the screen may use to shutdown the system
software and it will also prompt you question if you are really want to turn off. If the
answer is "Yes", the system software will shutdown. Otherwise, the system will remain
activate until the user requested it (refer to fig. 4.3).
The user/doctor is expected to be trained and have knowledge in the intended use and
