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 license-free in Europe�
SK 2020-D bodypack transmitter
You can connect one of the following Sennheiser microphones (to be ordered
separately) to the bodypack transmitter:
• Clip-on microphones:
ME 2-II, ME 4, MKE 1-ew, MKE 2-EW Gold
• Headmics:
ME 3-II, HS 2-ew BK, HS 2-ew BE, SL Headmic 1 SB, SL Headmic 1 BK,
SL Headmic 1 BE
• Hand-held microphones with special connecting cable:
e 825 S, e 835, e 845
In addition, you can connect any audio source (e�g� a flash / MP3 player) to the
bodypack transmitter�
SKM 2020-D radio microphone
This extremely rugged radio microphone can be used in various tour situations�
The radio microphone is easy to configure and use�
For storage and safe transportation, the radio microphone can be placed in the
charging case and secured with Velcro tape�
HDE 2020-D-II and EK 2020-D-II receivers
The receivers are easy to use and comfortable to wear� The built-in LC display
shows all the important in- formation 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-II 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�

Overview of the system
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�
ENDEFRITESNL
The L 2021-40 charger
The L 2021-40 charger can charge a total of 40 HDE 2020-D-II and/or
EK 2020-D-II receivers with their built-in rechargeable batteries� The channel
copy function lets you set all receivers to the same channel at the press of a
button�
In addition, the charger allows you to directly configure the receivers via a PC�
You can connect up to 125 chargers to a single PC, allowing you to simultaneously configure up to 5000 receivers�
Additional features of the charger:
• Quick charge of receiver rechargeable batteries�
• Highest possible operational reliability, since temperature and voltage of
the rechargeable batteries are monitored during charging�

CAUTION
DANGER DUE TO HEAT ACCUMULATION!
The charger and the receiver rechargeable batteries can get very hot during
charging� If the heat cannot dissipate, the devices can be damaged�
Make sure that the air vents of the charger are not covered or blocked�
Provide sufficient ventilation so that the maximum ambient temperature of
the charger does not exceed 40°C�
Keep the charger away from heat sources and never expose it to direct sun-
light�
The charger can be:
• placed on a table or cabinet
• installed in a 19" rack

The housing of the charger is designed so that it fits into a 19" rack� The charger can also be installed in a cabinet or similar�
CAUTION
RISKS WHEN RACK MOUNTING THE CHARGER!
When installing the device in a closed or multi-rack assembly, please consider
that, during operation, the ambient temperature, the mechanical loading and
the electrical potentials will be different from those of devices which are not
mounted into a rack�
The ambient temperature within the rack, cabinet or similar must not exceed
the temperature limit specified in the specifications�
When installing the device, take good care not to affect the ventilation required for safe operation� If necessary, provide additional ventilation�
Make sure the mechanical loading of the rack is even to avoid a hazardous
condition�
When connecting the device to the power supply, observe the information
indicated on the type plate� Avoid circuit overloading� If necessary, provide
overcurrent protection�
Ensure a reliable mains ground connection of the device by taking appropriate measures – especially when you are using an extension cable or a
multi-outlet power strip�
When installing the device in a closed or multi-rack assembly, please note
that intrinsically harmless leakage currents of the individual devices may accumulate, thereby exceeding the allowable limit value� As a remedy, ground
the rack via an additional ground connection�

be connected directly to an individual PC or integrated into an existing network� The charger cannot communicate with several PCs at the same time�
The charger also functions without connection to a PC�
Connecting the network cable
Use a standard network cable (RJ45 CAT�5E, to be ordered separately) to
connect the network socket 9 and an Ethernet socket of the network�
Install the “Conference Control” software�

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)
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�
