Hazard warnings on the EZL 2020-20 L charging case
The label shown on the left is attached to the rear of
the charging case. The symbols on this label have the
following meaning:
This symbol is intended to alert the user to the
presence of uninsulated dangerous voltage within
the device's enclosure that may be of sufficient
magnitude to constitute risk of fire or electric shock.
This symbol is intended to alert the user to the risk of
electric shock if the device is opened. There are no user
serviceable parts inside. Refer servicing to qualified
personnel only.
This symbol indicates the presence of important oper-
ating and maintenance instructions in the literature
accompanying this device.
Overloading
Do not overload wall outlets and extension cables as
this may result in fire and electric shock.

Important safety instructions
Danger of hearing damage due to high volumes
This is a professional transmission system. Commercial
use is subject to the rules and regulations of the trade
association responsible. Sennheiser, as the manu-
facturer, is therefore obliged to expressly point out
possible health risks arising from use.
The HDE 2020 D and EK 2020 D receivers are capable
of producing sound pressure exceeding 85 dB(A).
85 dB(A) is the sound pressure corresponding to the
maximum permissible volume which is by law (in
some countries) allowed to affect your hearing for
the duration of a working day. It is used as a basis
according to the specifications of industrial medicine.
Higher volumes or longer durations can damage your
hearing. At higher volumes, the duration must be
shortened in order to prevent hearing damage. The
following are sure signs that you have been subjected
to excessive noise for too long a time:
· You can hear ringing or whistling sounds in your
ears.
· You have the impression (even for a short time
only) that you can no longer hear high notes.
Intended use of the devices
Intended use includes:
· using the devices for professional purposes,
· having read this instruction manual, especially the
chapter "Important safety instructions" on page 2,
· using the devices within the operating conditions
and limitations described in this instruction
manual.
"Improper use" means using the devices other than as
described in this instruction manual, or under oper-
ating conditions which differ from those described
herein.
