Responsible use

Laser safety matters.

Laser classifications listed for the HJ350-D22 are Class 2 for OTDR/LS and Class 3B for VFL. Avoid direct eye exposure, never look into an active fiber or optical port, and follow appropriate laser-safety procedures. The HJ350 is a portable troubleshooting and diagnostic tool, not a laboratory or certification instrument.
