Warning:
 
These devices contain Class 1 laser products, and comply 
with 21 CFR 1040.10 and 1040.11 EN 60825-1 - Safety of Laser 
Products. 
Class 1 lasers are considered eye-safe; however, follow these 
appropriate safety measures:
Always make sure that the CVX switch is powered down before 
connecting or disconnecting any optical cables.
Always make sure all ports or unconnected optical cable ends are 
covered before powering up the CVX switch.
Never remove a cover from a port or attached optical cable while the 
CVX switch has power.
Caution: 
 
For proper operation, observe the following:
Never touch the end of the fiber in a connector with anything except 
an approved cleaner.
Always clean the end of the fiber in connectors and optical ports 
before connecting the cables. Use an approved cleaner, or a soft cloth 
with isopropyl alcohol.
Never use any optical cable that has been damaged, or that has been 
coiled tighter than a 35-mm radius curve.
