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 manufacturer, 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 operating conditions which differ from those described
herein.

Overview of the system
Overview of the system
The Tourguide System 2020 D offers optimum digital
speech transmission for conferences and guided tours
e.g. in factories or museums. The use of RF transmission allows freedom of movement for all members of
the group. Six preset intermodulation-free receiving
frequencies offer high flexibility and adaptability.
The Tourguide System 2020 D operates in the
863 MHz – 865 MHz frequency band, which is licensefree in Europe. For an overview, refer to page 56.

Overview of the system
HDE 2020 D and EK 2020 D receivers
The receivers are easy to use and comfortable to wear.
The built-in LC 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 EK 2020 D allows you to connect any headphones
or an induction loop for wearers of hearing aids.
The system can be expanded at any time by adding
additional receivers.
EZL 2020-20 L charging case
The charging case simultaneously recharges up to
20 stethoset receivers with their built-in rechargeable
batteries, as well as the BA 2015 accupack of the
bodypack transmitter/radio microphone. You can also
charge the bodypack transmitter with the BA 2015
accupack inserted plus an additional spare accupack.
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:
• Quick charge of accupacks.
• 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.
• Highest possible operational reliability, since
temperature and voltage of the accupacks are
monitored during charging.
• Long accupack service life due to overcharge
protection and recovery of deep-discharged accupacks.
• Safe storage and transportation of the system
components.

Using the components
Adjusting the radio microphone’s input sensitivity
The input sensitivity is adjusted too high when close
talking distances or speakers with loud voices cause
overmodulation in the transmission link. When the
audio input level is excessively high, the audio level
display (AF) shows full deflection.
If, on the other had, the input sensitivity is adjusted
too low, the transmission link will be undermodulated,
which would result in a signal with high background
noise.
The input sensitivity is correctly adjusted when the
audio level display (AF) only shows full deflection only
during the loudest passages.
To adjust the sensitivity of the radio microphone:
Press the SET button .

Warranty
The original Sennheiser product you have purchased is covered by a warranty of
24 months. The warranty period begins on the date of purchase of brand new,
unused products by the first end user. Please retain your sales receipt (or your
warranty certificate) as proof of purchase. Unless you submit proof of purchase,
which will be verified by your local Sennheiser service partner, you will be obliged
to pay for any repairs that are carried out. Proof of purchase must state the date of
purchase and name of the product.
We shall satisfy our warranty obligations by remedying any material or manufacturing faults free of charge at our discretion either by repair or by exchanging
individual parts or the entire appliance. Any defective parts removed from a
product during the course of a warranty claim shall become the property of
Sennheiser electronic GmbH & Co. KG.
The following cases are not covered by the above warranty:
• minor faults or deviations in the quality of a product which do not affect the
product’s value or fitness for its intended purpose
• any accessories supplied with the product
• rechargeable and disposable batteries (these products have a shorter service
life, the length of which also depends on the frequency of use)
• faults resulting from improper use (e.g. operating errors, mechanical damage,
incorrect operating voltage)
Proper use for the purposes of this warranty is defined as use of the product
under the conditions stated in the instructions for use.
• faults due to wear and tear
• any modification of Sennheiser products effected by you or a third party, unless
Sennheiser has given its prior written consent to the nature and extent of the
modification
• faults due to force majeure
• faults of which the purchaser was already aware at the time of purchase
All warranty claims become void if the product is tampered with by unauthorised
persons or repair shops.
Warranty claims can be enforced in any country throughout the world in which the
statutory rights of the country concerned are not in conflict with our warranty regulations. No other warranty claims or claims over and above the rights stated in
these terms and conditions will be accepted.
