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:
y You can hear ringing or whistling sounds in your
ears.
y You 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:
y using the equipment for commercial purposes,
y reading these instructions and, in particular, the
section “Important safety Instructions” on page 2,
y only 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.

Overview of the system
The HDE 2020 D stethoset receivers
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 EZL 2020-20 L charging case
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:
y Quick charge of accupacks.
y Automatic 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.
y Highest possible operational reliability, since
temperature and voltage of the accupacks are
monitored during charging.
y Long accupack service life due to overcharge
protection and recovery of deep-discharged
accupacks.
y Safe carrying and storage of system components.

approx. 3½ hours at room temperature.
y Alternatively, you can remove the accupack from
the bodypack transmitter and insert it into the
charging compartment for accupack/bodypack
transmitter , as described in the following
section.
y In the charging case, there is no error indication
like the one on the quick charger L 2015 (“red

Charging the BA 2015 accupack
To charge the accupack of the wireless microphone or
bodypack transmitter:
Remove the accupack, as described on page 23 or
page 24.
Place the accupack into the charging compartment
for the accupack/bodypack transmitter as
shown in the diagram on the left.
The red LED CHARGE/ERROR of the charging
compartment lights up.
When the accupack is fully charged, the green LED
READY lights up.
Notes:
y Charging a completely discharged accupack takes
approx. 3½ hours at room temperature. It is
normal for the accupacks to get hot during
charging.
y However, the charging process may take longer
if:
– the accupack is deep-discharged and first has
to be reconditioned by a deep discharge
recovery charge,
– the ambient temperature is close to or over
40°C, since, in order to protect the accupack, the
charging process will be interrupted until the
temperature has dropped to a safe level.
y For safety reasons, each charging process will be
interrupted after 4 hours.
y When not using the BA 2015 accupack for
extended periods of time, charge it about every
three to six months.

Notes:
y Charging a completely discharged rechargeable
battery takes approx. 2½ hours at room
temperature.
y However, the charging process may take longer if:
– the rechargeable battery is deep discharged
and first has to be reconditioned by a deep
discharge recovery charge,
– the temperature of the built-in rechargeable
battery is over 40°C or below 3°C, since, in order
to protect the rechargeable battery, the
charging process will be interrupted until the
temperature is again within the admissible
range (the LED
flashes red).
y An additional temperature protection prevents
overheating inside the charging case. If the
temperature inside the charging case exceeds
safety limits, the charging process will be
interrupted and will only be restarted when the
charging case has cooled down.
y When not using the receivers for extended
periods of time, charge them about every six
months in order to prevent deep discharge
damage to the rechargeable batteries.

Warranty
The warranty period for this genuine Sennheiser product is 24 months from the
date of purchase. The warranty period starts on the date of purchase of brand-new,
unused products by the initial end-user. For this reason, we recommend that the
sales receipt be retained as proof of purchase. Without this proof (which is checked
by the responsible Sennheiser service agent) you will not be reimbursed for any
repairs that are carried out. The date of purchase and the name of the product must
appear on the sales receipt.
At our discretion, the warranty covers, free of charge, the remedy of material and
manufacturing defects through repair or replacement of either individual parts or
the entire device. In the event of a warranty claim, the faulty parts removed from
the product become the property of Sennheiser electronic GmbH & Co. KG, or the
Service agent.
The warranty excludes:
y Immaterial defects or nonconformities in the quality of the product that do not
affect the value and normal use
y Accessories that come with the product
y Rechargeable batteries and batteries (by nature, these products have a shorter
service life, the length of which also depends on how much they are used)
y Defects resulting from improper use (e. g. operator error, mechanical damage,
incorrect operating voltage)
Proper use means use of the product under the conditions described in the
instructions for use.
y Wear and tear
y Modifications of Sennheiser products undertaken by you or others, unless the
type and scope of the modification has been previously approved in writing by
Sennheiser
y Defects resulting from force majeure
y Known defects at the time of purchase
The warranty is void if the product is manipulated by non-authorised persons or
repair stations.
The warranty can be claimed in all countries outside the U.S. provided that no
national law limits our terms of warranty. No claims can be made under the
warranty other or more extensive than those described here.
