Regulatory Compliance

EYE SAFETY

This laser based multimode transceiver is a Class 1 product. It

complies with IEC 60825-1 and FDA 21 CFR 1040.10 and

1040.11.

To meet laser safety requirements the transceiver shall be oper-

ated within the maximum operating limits.

Caution

All adjustments have been made at the factory prior to ship-

ment of the devices. No maintenance or alteration to the

device is required.

Tampering with or modifying the performance of the device

will result in voided product warranty.

Note

Failure to adhere to the above restrictions could result in a modifica-

tion that is considered an act of “manufacturing”, and will require,

under law, recertification of the modified product with the U.S. Food
