Safety check
Upon completion of any service or repairs to this device, ask the service technician
to perform safety checks to determine that the device is in safe operating order.
Danger of hearing damage due to high volumes
This is a professional 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.
This system is 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:
y You can hear ringing or whistling sounds in your ears.
y 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 of the devices includes:
y using the device for professional purposes,
y having read these instructions, especially the chapter see „Important safety
instructions“ on page 5,
y using the device within the operating conditions and limitations described in
this instruction manual.

The tourguide UHF system
The tourguide UHF system
The tourguide UHF system consists of the EK 1038 receiver in combination with a transmitter of the evolution wireless series G2. The
system offers optimum speech transmission for guided tours and
interpretation applications 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 1038 receiver
with different transmitters, the system can be optimally adapted to
your individual needs.
The system has superb audio quality with an increased signal-tonoise ratio and dynamic range due to the inclusion of Sennheiser’s
HDX noise reduction system.
System components
The components of the system are:
y EK 1038 receiver
y BA 2015 accupack
y L 2015 charger
y NT 1 or NT 3 plug-in mains unit
y GP 03 headphones with stereo jack plug
y transmitter (please specify when ordering)

EK 1038 receiver
Preparing for use
Inserting and changing the battery pack/batteries
For powering the units, we recommend using the supplied BA 2015
battery pack. The battery pack can be recharged in the L 2015
charger while remaining in the receiver (see “Charging the
rechargeable battery BA 2015” on page 27).
Accupacks ensure economical and environmentally friendly operation of the tourguide UHF system during daily use.
If no power supply is available for recharging the battery pack, you
can alternatively use 1.5 V AA size batteries.
Press the two unlocking buttons and open the battery com-
partment cover .
Insert the battery pack or the batteries as shown on the left.
Please observe correct polarity when inserting the battery pack
or the batteries.
Close the battery compartment. The battery compartment
cover locks into place with an audible click.
How to properly use the battery pack or the batteries
For battery pack operation, only use the BA 2015 battery pack in
order to ensure optimum operational reliability. Batteries and
rechargeable battery cells have different discharging curves. The
receiver is able to identify the BA 2015 battery pack and to use it to
full capacity. It also adapts the battery status display according to
the type of power supply used (batteries or battery pack). Individual rechargeable battery cells will not be identified as battery packs.
After use (e.g. during the night), charge the BA 2015 battery
pack of the receiver in the L 2015 charger. The charging time is
approx. 2.5 hours, at which time the unit then switches to trickle
charging.
If you do not use the receiver for extended periods of time (e.g.
while you are on holiday), remove the battery pack or the batteries. After three months at the latest, the battery packs will need
a refresh charge in the L 2015 charger. This prevents damage to
the battery pack due to self-discharge.
Connecting the headphones
You must only connect headphones with a stereo jack plug and a
minimum impedance of 8
Ω to the receiver.
Connect the headphones to the receiver’s 3.5 mm jack socket
(PHONES) .
