IMPORTANT SAFETY / COMPLIANCE INFO
Class 2 wiring: to reduce the risk of electric shock, the external wiring
connected to the terminals marked with "class 2 wiring" requires installation
of class 2 wiring by an authorized/trained person or by using ready-made leads
or cords.
This unit has NOT been designed for use in mobile applications, such as:
mobile discobars, mobile PA systems, live bands and audio rental systems.
Using it in such applications will lead to product damage and safety risks.
Do not remove or defeat the ground prong on the power cord, as this will
constitute a shock hazard. Equipment should be connected to a mains
socket outlet with a protective earthing connection. This plug is the main
disconnecting device and should remain readily operable. There are no user
interchangeable parts. Please contact Biamp Technical Support or your local
distributor for all service requirements.
