The EZL 2020-20 L charging case is a Class 1 device. It
must only be connected to properly grounded power
outlets.
Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug
has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety.
If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete
outlet.
This device must be operated only from the type of
power supply indicated on the marking label. lf you
are not sure of the type of power supply to your
building, consult your dealer or local power company.
Do not overload wall outlets and extension cables as
this may result in fire and electric shock.
Protect the mains cable from being walked on or
pinched, particularly at plugs, convenience
receptacles, and the point where they exit from the
device.
Only use attachments/accessories specified by
Sennheiser.
Use only with the cart, stand, tripod, bracket, or table
specified by Sennheiser, or sold with the device. When
a cart is used, use caution when moving the cart/
device combination to avoid injury from tip-over.
Unplug the device during lightning storms or when
unused for long periods of time.
