Laser Safety

GTS-820A series uses the visible laser beam for auto tracking, optical communication. The GTS-820A series products are manufactured and sold in accordance with “Radiation Safety of Laser Products, Equipment Classification, Requirements and User‘s Guide” (IEC Publication 60825-1) or “Performance Standards for Light-Emitting Products” (FDA/BRH 21 CFR 1040) provided on the safety standards for laser beam.

As per the said standards, GTS-820A series is classified as “Class 2 (CLASS II) Laser Products”. The laser beam belongs not very dangerous type but we request you to keep and understand “Safety standard for users” as mentioned in the manual instruction.

In case of any failure, do not disassemble the instrument. Contact TOPCON or your TOPCON dealer. Laser class of each mode is as follows.
