Important safety instructions

Danger due to high volume!

The equipment is used for commercial purposes.

Commercial use is subject to the rules and regulations

of the trade association responsible. Sennheiser, as

the manufacturer, is therefore obliged to expressly

point out possible health risks arising from use.

The HDE 2020 D stethoset 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:

yYou can hear ringing or whistling sounds in your

ears.

yYou have the impression (even for a short time

only) that you can no longer hear high notes.

Normal use of the equipment

Normal use of the equipment includes:

yusing the equipment for commercial purposes,

yreading these instructions and, in particular, the

section “Important safety Instructions” on page 2,

yonly using the equipment under the operating

conditions, as described in these instructions.

Using the equipment other than as described in these

instructions or non-compliance with the operating

conditions is considered improper use.

The stethoset receivers are easy to use and

comfortable to wear. The built-in display shows all the

important information at a glance (receiving channel,

reception quality, charge status of the built-in

lithium-polymer rechargeable battery as well as the

currently set volume). The rocker button allows fast

and easy setting of the desired channel.

The system can be expanded at any time by adding

additional stethoset receivers.

The charging case simultaneously recharges the

rechargeable batteries of up to 20 stethoset receivers

and the accupack of the bodypack transmitter/

wireless microphone. You do not have do remove the

accupack from the bodypack transmitter to recharge

it. You can recharge one other accupack in addition to

the bodypack transmitter. The channel copy function

lets you set all receivers to the same channel at the

press of a button.

Additional features of the charging case:

yQuick charge of accupacks.

yAutomatic detection of full charge and subsequent

switching to trickle charging so the accupacks can

remain in the charger even when they have been

fully charged.

yHighest possible operational reliability, since

temperature and voltage of the accupacks are

monitored during charging.

yLong accupack service life due to overcharge

protection and recovery of deep-discharged

accupacks.

ySafe carrying and storage of system components.
