Datasheet
4. Safety instructions
The SF23/B emits ionizing laser radiation. The level of the laser emission is Class 1 which indicates that the laser beam is safe to
look at with the unaided eye but must not be viewed using binoculars or other optical devices. Notwithstanding the safety rating,
avoid looking into the beam and switch the unit off when working in the area.
Caution
The use of optical instruments with this product will increase eye hazard.
The SF23/B should not be disassembled or modified in any way. The laser eye safety rating depends on the mechanical integrity
of the optics and electronics so if these are damaged do not continue using the SF23/B. There are no user serviceable parts and
maintenance or repair must only be carried out by the manufacturer or a qualified service agent.
No regular maintenance is required for the SF23/B but if the lenses start to collect dust then they may be wiped with suitable lens
cleaning materials.
