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 power cable and battery are connected.
Unless otherwise specified, all interfaces are intended for
connection to Safety Extra Low Voltage (SELV) circuits only.
Capacitors inside the unit may be charged even if the unit has
been disconnected from its electrical supply.
