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 opera-
tion 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 µ.
̈ 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 µ 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). Individ-
ual 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 batter-
ies. 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) ·.
