Overloading
Do not overload wall outlets and extension cables as this may result in fire
and electric shock.
If you switch on several chargers at the same time, you can blow the fuse
due to the high switch-on voltage! Therefore, never switch on more than
three chargers at the same time, e.g. via a switchable multi-outlet power
strip.

The L 2021-40 charger
ES
NL
The L 2021-40 charger is part of the Tourguide 2020 D system. The
Tourguide 2020 D system offers optimum digital speech transmission for
guided tours e.g. in factories or museums and during conferences. The
use of RF transmission allows freedom of movement for all members of
the group. Six fixed transmission frequencies in “Tourguide mode” and
eight transmission frequencies in “Conference mode“ offer high flexibility
and adaptability. The L 2021-40 charger simultaneously recharges up to
40 HDE 2020 D stethoset 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 stethoset
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

Putting the charger into operation
Putting the charger into operation
NOTICE! 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.
DE
EN
FR
IT
̈ Make sure that the air vents of the charger are not covered
or blocked.
̈ Make sure that the ambient temperature of the charger
does not exceed 40°C. If necessary, provide additional
ventilation.
̈ Keep the charger away from heat sources and never expose
it to direct sunlight.
The charger can be:
• placed on a table or cabinet
• installed in a 19” rack
• installed in a cabinet or similar
ES
NL
When using the “Conference Control” software, it automatically sorts its
charger displays according to ascending serial numbers. The assignment of
the charger displays of the software to the chargers becomes easier and
clearer if you install the chargers according to ascending serial numbers.
Placing the charger on a table or cabinet
The charger has four plastic feet to ensure that it cannot slip on the surface
on which it is placed.
NOTICE! Risk of staining of furniture surfaces!
Some furniture surfaces have been treated with varnish,
polish or synthetics which might cause stains when they
come into contact with other synthetics. Despite a thorough
testing of the synthetics used by us, we cannot rule out the
possibility of staining.
̈ Do not place the charger on delicate surfaces.
̈ Place the charger on a table, cabinet or similar.

charger can also be installed in a cabinet or similar.
CAUTION! Risks when rack mounting the charger!
DE
EN
FR
IT
When installing the device in a closed or multi-rack assembly,
please consider that, during operation, the ambient temper-
ature, 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.
ES
NL
̈ 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.
̈ Use eight screws to fasten the charger.

Putting the charger into operation
Connecting the charger to a PC
You can connect one or several chargers to a PC. The supplied “Conference
Control” software allows you to centrally and easily configure and monitor
several chargers and receivers.
For this, the charger requires a network connection with a PC. The charger
can be connected directly to an individual PC or integrated into an existing
network. The charger cannot communicate with several PCs at the same
time.
DE
EN
FR
IT
The charger also functions without connection to a PC.
Connecting the network cable
̈ Use a standard network cable (RJ45 CAT.5E, not included in the delivery)
to connect the network socket ¾ and an Ethernet socket of the
network.
̈ Install the “Conference Control” software.
̈ Configure the network communication between the “Conference
Control” software and the charger (the instruction manual of the
“Conference Control” software on the enclosed CD).
ES
NL
Connecting the charger to and disconnecting it from the
mains
CAUTION! Danger due to electric current!
If you connect the charger to an unsuitable power supply, this
can cause damage to the device!
̈ Use a mains cable with a 3-pin IEC mains connector to
ensure a reliable mains ground connection of the charger –
especially when you are using an extension cable or a
multi-outlet power strip.
̈ Avoid circuit overloading. If necessary, provide overcurrent
protection.
To connect the charger to the mains:
̈ Connect the mains cable (not included in the delivery) to the mains
socket µ.
̈ Plug the mains connector into a wall socket.
To disconnect the charger from the mains:
̈ Pull out the mains connector from the wall socket.
