CHARGING BATTERIES
Prior to use this system the internal 12V battery need to be charged for 12 hours. If the Power-switch is in OFF
position and the system is connected to mains, the battery will be (re)charged and the Charge-Led lights!!
Note: Pull the plug out of the mains outlet if the battery is fully charged!!
Before the device the first time is actuated, please charge the battery at least 12 hours and max. 72 hours! Battery
should be regularly charged. For optimal battery life the battery should be charged at least 1x per month. Please
note that if you do not load within 6 weeks, the battery becomes defective !!
TROUBLESHOOTING
One certain method of determining if a speaker is faulty is to substitute a speaker that is known to work correctly for
the suspected problem speaker. If the "normally correct speaker" is experiencing the same difficulties or problems
as the suspected problem speaker, use the information below to isolate the problem.
Problem
No output
Intermittent
Constant noise,
buzzing and/or
humming
Poor low-
frequency output
4
Possible cause
Action
Cables
Reseat all connectors
Substitute known good cables
Check solder joins
Inspect cable for damage
Inspect wire or connector for stray strand that may short
Poor connections
While it is possible for a faulty speaker to exhibit intermittent output,
it's more likely that an output cable/connector is the problem. Check
the soldering on your connectors.
Faulty electronic
Any constant noise originates in the amplifier, mixer, signal
processing, source device in the signal devices, or line-level wiring.
Check and correct system grounding as required. Chain check for
noisy sources or electronic components. Check wiring for shielding.
Improper polarity
When two speakers in close proximity to each other are connected
out-of-polarity, they can partially cancel each other out, especially at
low frequencies. Check your speaker cables to be sure they are all
identically wired and connected. Check the balanced line signal
cables to be sure they are all correctly wired.
