WARNING
Use the external power supply indoors only.
Position the unit so that the air can circulate freely around it.
Operation of any electrical instrument around flammable gases or
fumes constitutes a major safety hazard.
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 power cable and battery are connected.
Capacitors inside the unit may be charged even if the unit has been
disconnected from its electrical supply.
Use only the listed and certified USB power adapter provided by
EXFO with your unit. It provides reinforced insulation between
