PREPARATION
Battery charging:
Connect the included power cable to the port of the sound system ~220-240V 50/60Hz (29), blue
charging mode indicator CHARGING (25) will light up.
Battery should be charged for approximately 8 to 12 hours. When battery has fully charged, red
indicator FULL (24) will light up.
If the battery has run out of charge, switch off the sound system immediately (set the
POWER (27) switch to OFF (CHARGING) and charge the battery of the sound system by
connecting it to the mains supply.
Low battery manifests itself through sound distortions and reduction in volume.
If the sound system is switched on during the charging (the POWER (27) switch is set to
ON/AC), the battery charge time will be longer.
To extend the service life of the battery, never leave it uncharged.
If you will not use the sound system for a long time, charge the battery every 3 months.

CONNECTING AN EXTERNAL 12V DC POWER SUPPLY
The sound system can run from an external DC power supply unit with an output voltage of
12-15V, and a power of at least 80W.
Before feeding the sound system from an external power supply unit, disconnect the power cord
from the socket ~220V-240V 50/60 Hz (29).
Observing the polarity is important when connecting cables. Incorrect polarity can damage
your sound system or other equipment!
Connect the ʺ+ʺ output lead of the external power supply unit to the red terminal of BATTERY
12V INPUT (26), and the ʺ-ʺ lead, to the black terminal.
Then, set the POWER (27) switch to ON/DC.
Do not connect other electric devices (e.g. a 12V lamp) to the BATTERY 12V INPUT (26)
terminals of the sound system.
USE
Switching on:
The sound system can be powered in two ways:
1) from a 230V, ~50/60Hz mains supply (set the POWER (27) switch to ON/AC),
2) from a 12V battery (set the POWER (27) switch to ON/DC).
Volume adjustment:
The sound system has two volume controllers:
a) VOLUME (21), adjusts (limits) the maximum volume.
