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.

Replacement parts

When replacement parts are required, be sure the

service technician uses replacement parts specified by

Sennheiser or those having the same characteristics

as the original part. Unauthorized substitutions may

result in fire, electric shock, or other hazards.

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.
