Power Supply
The unit can be operated with mains voltage and for mobile use via rechargeable batteries.
Mains operation
To operate the unit via the mains, connect the mains cable provided to the power input and to a mains
socket. When the unit is connected to the mains, the automatic charging for the rechargeable batteries is
always active (the
CHARGE
indicator lights red) even if the unit is switched off. It is not necessary to switch
on the unit for recharging; however, it can be operated during the recharging process. Once the recharging
process has been completed, the charge indicator will go out. To prevent unnecessary power consumption,
always disconnect the mains plug from the mains socket if the unit is not used for a longer period.
Battery operation
During battery operation, the 4-digit LED meter will indicate the charging state of the rechargeable batteries.
When the capacity of the batteries is sufficient, all indicators light up. If the
LOW
indicator lights red, the
batteries are almost discharged and should be recharged as soon as possible. Then connect the device to
the mains power to charge the batteries.
The PA system ships with an internal battery that can power continuous playback at full volume for up to 4
hours. Prior to operating the PA system off mains for the first time, the battery must be fully charged.
Charging time is 4 hours.
Notes
To prevent damage to the battery due to deep discharge and to prevent a reduction of its lifetime, please
observe the following notes:
•
Always fully recharge the battery prior to initial operation and after longer storage.
•
Fully recharge the battery prior to longer storage and at least every month during storage.
Installing an additional battery
RISK OF ELECTRIC SHOCK!
Switch off the device and disconnect it from the mains before opening any covers.
With an additional battery the operation time can be doubled and the PA system can continuously play music
at full volume for up to 8 hours. Charging time for two batteries is 10 hours. Please use the accessory
batteries only which meet the technical requirements.
Follow the steps below to install the battery:
1) Loosen the outer Phillips screws and the inner hexagon socket screw and remove the battery
compartment cover.
2) The power supply cables are color-coded and equipped with blade receptacles. Connect the battery to
the free cable observing the correct polarity (red = positive pole, black = negative pole) and insert the
battery into the compartment.
3) Replace the battery compartment cover.
