3 Safety Notes
The unit corresponds to all relevant directives
of the EU and is therefore marked with
CAUTION Never operate the megaphone
near the ear of another person!
Due to the amplified voice or a
howling sound, damage to the
hearing can be caused .
•
Never deposit the unit in humid environ-
ments, and protect it against excessive heat
(admissible op erating temperature range
0 – 40 °C) .
•
Avoid using the unit in the rain . Make sure
that no liquid penetrates into the unit .
•
For cleaning only use a soft cloth, dry or
slightly wet; never use chemicals or aggres-
sive detergents .
•
No guarantee claims for the unit and no li-
ability for any resulting personal damage or
material damage will be accepted if the unit
is used for purposes other than originally
intended, if it is not correctly connected or
operated, or if it is not repaired in an expert
way .
If the unit is to be put out of oper-
ation definitively, take it to a local
recycling plant for a disposal which
is not harmful to the environment .
4 Setting into Operation
The unit can alternatively be operated either
via batteries or an external 12 V power supply .
When an external power supply is connected,
the inserted bat teries wil be switched off .
4.1 Inserting batteries
1) Release the locking clip (1) of the battery
compartment, and fold up the battery com-
partment cover (2) .
2) Insert eight 1 .5 V, C size batteries into the
plastic supports of the battery compart-
ment . Observe the correct polarity (see im-
print in the battery compartment) .
3) Close the battery compartment cover again
and lock it with the locking clip .
If not used for a longer time (e . g . more than
one week), the batteries should be removed .
Thus, the unit will not be damaged in case the
batteries should leak .
Never put batteries in the household
waste . To protect the environment,
always take them to a special waste
disposal, e . g . collection container at
your retailer .
4.2 External power supply
To connect an external 12 V power supply,
e . g . 12 V power supply unit, 12 V battery,
remove the protection cover above the jack
"DC-12V" (4), and connect the power supply
via a low-voltage plug 5 .5 mm / 2 .1 mm (out-
side / inside diameter) . The positive pole must
be at the centre contact of the plug .
As an external power supply, also a 12 V
car battery can be used whose negative pole
is connect ed to ground . For this, connect the
supplied adapter cable to the jack "DC-12V"
and to the cigarette lighter socket in the car .
For an optimum electric contact, it should not
be soiled by cigarette ash . If necessary, clean
it with a soft, dry cloth .
