When tissue builds up during a cutting procedure, remove the tissue using a clean gauze pad. Do not use alcohol on an initiated tip.

Consult the accessories index for a complete listing of fibers and tips.

When procedure is complete, turn off the laser, appropriately dispose of the tip, clean handpiece with CaviCide™ or similar material,

cover with protective cover, and place the handpiece in the holder. Always clean and use a new tip prior to use.

DESCRIPTION OF LASER OPERATION MODES

Picasso and Picasso Lite have two modes of operation: CONTINUOUS and REPEAT (or PULSE) MODE. In CONTINUOUS mode, the

laser will deliver output radiation at the power level specified by the user for as long as the foot switch is held down. In REPEAT /

PULSE mode, the laser will deliver output radiation at the power level specified by the user and in a pulse format defined by the user

for Picasso or 30 ms for Picasso Lite. In pulse mode, the wattage is reduced meaning that a setting on 1.0 W in pulse mode may

produce only 0.5 W of energy at the tip. In this section, the operation of the laser is described.

SPEED MODE

To select the SPEED MODE of operation, press the key marked with the rabbit symbol. In this mode, the preset from the factory is 1.8 W,

continuous operation while the foot control is depressed. This is a continuous mode of operation. The only variable parameter is the

output power. The user can increase and decrease power shown in watts by pressing the corresponding up/down arrow buttons.

To operate the laser in SPEED MODE, press the STANDBY/READY button. The laser will now deliver output radiation as long as the

user holds the foot switch down. An audible signal will be sounded while the laser is active and the ready button will flash.

SPEED MODE output power can be changed at any time using the up/down arrow buttons. The user may lock this new parameter

into the SPEED MODE setting by first selecting desired parameter for power and then by pushing and holding down the Speed button

for approximately 5 seconds. The system will momentarily blink off and then on again symbolizing the new parameter has been set.

COMFORT MODE

To select the COMFORT MODE of operation, press the key marked with the HAPPY FACE symbol. In this mode, the preset from the

factory is 1.8 W and 30 ms on time and 30 ms off time. This is a PULSED MODE of operation. The user can increase and decrease

power shown in watts by pressing the corresponding up/down arrow buttons.

Once the user has selected the desired wattage, the unit may be enabled by pressing the STANDBY/READY button. After the

STANDBY/READY button has been pressed, the user may operate the laser at this point by depressing the foot switch. The laser will

respond by outputting radiation at the desired power level for a period of 30 ms. An audible signal will be sounded while the laser

is active and the ready light will be flashing. At the end of the ON PULSE, the laser will pause for a period of 30 ms. After the OFF

TIME has passed, the laser will repeat this pattern for as long as the foot switch is depressed. Laser treatment may be interrupted at

any time by releasing the foot switch. To resume treatment, simply depress the foot switch.

The system will momentarily blink off and then on again symbolizing the new parameter has been set.

DIFFUSION MODE

To select the DIFFUSION MODE of operation, press the key with the three wavy lines. This is a continuous mode of operation. In this

mode, the laser is preset from the factory at 0.5 W. The only variable parameter is the output power. The user can increase power

shown in watts by pressing the corresponding arrow buttons.

To operate the laser in DIFFUSION MODE, press the STANDBY/READY button. The laser will deliver output radiation as long as the

user holds the foot switch down. An audible signal will be sounded while the laser is active and the ready button will flash.

DIFFUSION MODE output power can be changed at any time using the up/down arrow buttons. The user may lock this new

parameter into the DIFFUSION MODE setting by first selecting desired parameter for power and then by pushing and holding down

the DIFFUSION button for approximately five seconds. The system will momentarily blink off and then on again symbolizing the new

parameter has been set. The DIFFUSION MODE can be used with a non-initiated tip for the treatment of ulcers.
