The L 1039-10 charger
The L 1039-10 charger is part of the Tourguide 1039 system.
The Tourguide 1039 system consists of the EK 1039 receiver and a suitable trans-
mitter of the evolution wireless G3 or 2000 series. The system offers optimum
speech transmission for guided tours, small conferences and interpretation appli-
cations with one or several speakers. The use of RF transmission allows freedom of
movement for all members of the group. Due to the possibility of combining the
EK 1039 receiver with different transmitters, the system can be optimally adapted
to your individual needs.
The L 1039-10 charger can charge up to ten EK 1039 receivers with their BA 2015
accupacks installed. In addition, the charger allows you to charge all bodypack
receivers or bodypack transmitters of the Sennheiser evolution wireless G3,
evolution wireless G2 or 2000 series.
A list of accessories can be found on the L 1039-10 product page at
www.sennheiser.com.

Putting the charger into operation
Putting the charger into operation
The charger can be:
• placed on a table or cabinet,
• installed in a 19" rack,
• fixedly installed in a cabinet or transport case.
Installing the charger
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 transport case.
왘Slide the charger into the 19" rack.
왘Fasten the charger to the rack by screwing 4 screws through the 4 mounting
holes 4.
왘Attach the mains unit to the rack (e.g. using Velcro tape) so that the mains
cables are not mechanically loaded.
CAUTION
Danger due to heat accumulation!
The charger and the receivers can get very hot during charging. If the heat cannot
dissipate, the products can be damaged.
왘Provide sufficient ventilation so that the ambient temperature of the charger
does not exceed the temperature limit specified in the specifications (see
page 11).
왘Keep the charger away from heat sources and never expose it to direct sunlight.
CAUTION
Risks when rack mounting the charger!
When installing the product in a closed or multi-rack assembly, please consider
that
• the ambient temperature within the rack may increase considerably,
• high mechanical loading may occur, e.g. acting on the housings and cables,
• intrinsically harmless leakage currents of the individual mains units may accu-
mulate, thereby exceeding the allowable limit values.
This can cause material damage and electric shock.
왘Make sure that the mechanical loading of the rack is even.
왘Make sure that the ambient temperature within the rack does not exceed the
temperature limit specified in the specifications (see page 11). Ensure sufficient
ventilation; if necessary, provide additional ventilation.
왘When connecting the charger to the mains, observe the information indicated
on the type plate. Avoid circuit overloading. If necessary, provide overcurrent
protection.
왘Ground the rack via an additional ground connection.

Connecting the charger to and disconnecting it from the
mains
To connect the charger to the mains and switch it on:
왘Connect the hollow jack plug of the of the NT 12-50C mains unit to the hollow
jack socket 6of the charger.
왘Pass the cable of the mains unit through the cable grip 5as shown.
왘Connect the mains cable (EU, UK or US version) to the mains unit and to a wall
socket.
All status LEDs 3and 8light up for a brief moment. The charger is switched on
and in standby mode.
To switch the charger off and disconnect it from the mains:
왘Pull out the mains plug from the wall socket.

Charging the receivers
8|L 1039-10
Charging the receivers
왘Insert the bodypack receiver/transmitter with the BA 2015 accupack installed
into any of the charging compartments 2until it locks into place with an
audible click.
The accupack is being charged. The status LEDs 3and 8indicate the charging
process.
When an accupack is fully charged, the charging process stops automatically.
Accupacks that are left unused for extended periods of time lose a percentage of
their electrical charge. This is independent of whether the bodypack receivers/
transmitters are stored in the charger’s charging compartments or not.
To make sure that you always use fully charged accupacks, we recommend the
following steps:
왘Fully charge the accupacks for about 4-5 hours before use. Recharge the accu-
packs every 2 months at the latest.
If you store the bodypack receivers/transmitters outside the charger:
왘Insert the bodypack receivers/transmitters into the charger as desribed above.
왘Switch the charger on.
If you store the bodypack receivers/transmitters in the charger’s charging
compartments:
왘Switch the charger off and on again.
When the status LED 8of a charging compartment lights up green, the accupack
of the corresponding bodypack receiver/transmitter is fully charged.
When the status LED lights up red, the accupack is being charged.

Cleaning and maintaining the L 1039-10
Indications of the status LEDs
Charging times
With a completely discharged accupack and at room temperature, the charging
times are as follows:
However, charging may take longer under the following circumstances:
• 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 45°C/113°F; in order to protect the
accupack, the charging power will be reduced until the accupack temperature
has dropped to an admissible value.
Charging will be aborted and the status LED 3 will start flashing red under the
following circumstances:
• The accupack temperature is too low or too high (see “Specifications” on
page 11); charging starts automatically when the accupack temperature is
within the charging temperature range.
• The accupack is defective.
Cleaning and maintaining the L 1039-10
왘Remove all bodypack receivers/transmitters from the charging compartments.
왘Before cleaning, disconnect the mains unit from the mains.
왘Use a soft, dry cloth for cleaning.
왘Use a brush or similar to remove dust from the charging compartments.
