					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.

					Putting the charger into operation   
					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.   
					̈ Provide sufficient ventilation so that the ambient temperature of the charger   
					does not exceed the temperature limit specified in the specifications (see   
					page 11).   
					̈ 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,   
					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.   
					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.   
					̈ Make sure that the mechanical loading of the rack is even.   
					̈ Make sure that the ambient temperature within the rack does not exceed the   
					
					ventilation; if necessary, provide additional ventilation.   
					̈ When connecting the charger to the mains, observe the information indicated   
					on the type plate. Avoid circuit overloading. If necessary, provide overcurrent   
					protection.   
					̈ Ground the rack via an additional ground connection.   
					̈ Slide the charger into the 19" rack.   
					̈ Fasten the charger to the rack by screwing 4 screws through the 4 mounting   
					
					̈ Attach the mains unit to the rack (e.g. using Velcro tape) so that the mains   
					cables are not mechanically loaded.

					Connecting the charger to and disconnecting it from the   
					mains   
					To connect the charger to the mains and switch it on:   
					̈ Connect the hollow jack plug of the of the NT 12-50C mains unit to the hollow   
					
					
					̈ Connect the mains cable (EU, UK or US version) to the mains unit and to a wall   
					socket.

					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:   
					̈ Fully 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:   
					̈ Insert the bodypack receivers/transmitters into the charger as desribed above.   
					̈ Switch the charger on.   
					If you store the bodypack receivers/transmitters in the charger’s charging   
					compartments:   
					̈ Switch the charger off and on again.   
					
					of the corresponding bodypack receiver/transmitter is fully charged.   
					When the status LED lights up red, the accupack is being charged.

					Charging times   
					With a completely discharged accupack and at room temperature, the charging   
					times are as follows:   
					Capacity obtained   
					Charging time   
					approx. 100%   
					typ. 3-4 hours   
					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.   
					
					following circumstances:   
					• 
					The accupack temperature is too low or too high (see “Specifications” on   
					
					within the charging temperature range.   
					• 
					The accupack is defective.   
					Cleaning and maintaining the L 1039-10   
					CAUTION   
					Liquids can damage the electronics of the product!   
					Liquids entering the housing of the product can cause a short-circuit and damage   
					the electronics.   
					̈ Keep all liquids away from the product.   
					̈ Do not use any solvents or cleansing agents.   
					̈ Remove all bodypack receivers/transmitters from the charging compartments.   
					̈ Before cleaning, disconnect the mains unit from the mains.   
					̈ Use a soft, dry cloth for cleaning.   
					̈ Use a brush or similar to remove dust from the charging compartments.
