Optical Power Expert
Use the external power supply (USB power adapter) indoors
only.
Never connect the unit to the AC mains (with the USB power
adapter) when it is used outdoors.
To avoid electrical shock, do not operate the unit if any part of
the outer surface (covers, panels, etc.) is damaged.
Only authorized personnel should carry out adjustments,
maintenance or repair of opened units under voltage. A person
qualified in first aid must also be present. Do not replace any
components while the USB cable and battery are connected.
Unless otherwise specified, all interfaces are intended for
connection to Safety Extra Low Voltage (SELV) circuits only.
Use only the listed and/or certified USB power adapter with
your unit. It provides reinforced insulation between primary
and secondary, and is suitably rated for the country where the
unit is sold. EXFO cannot be held responsible for the safety of
the user if the latter uses accessories not recommended by
EXFO.
Capacitors inside the unit may be charged even if the unit has
been disconnected from its electrical supply.
