EQUIPMENT SAFETY ITEMS
Laser Beam
The equipment uses a low intensity laser beam (red laser) to indicate the infrared laser irradiation
point of the laser therapy handpiece.
As the laser beam passes through the same delivery system as the working beam, it offers a good
way to check the integrity of the delivery system. If the target beam is not present in the distal end
of the delivery system, if its integrity is reduced or if it seems diffuse, this is a possible indication that
the delivery system is damaged or not working properly.
Alerts
For operator’s safety, during emission of laser light, the equipment sounds an alarm.
Spacer
A spacer is sent to be inserted into the tip of the optical fiber, so as to have a contact application,
i.e., the spacer is an applied part of the product. To replace the spacer, simply pull out the one that
has already been used, clean the equipment and the new spacer, according to item “CLEANING/
DISINFECTING”, and insert it into the end of the optical fiber.
Handpiece Led
When the led of the handpiece is blinking fast, the laser has been activated.
