AC power cord is not connected to the
power
supply or is not connected to a power
supply correctly.
Please check that the AC power cord is
connected correctly.
There is no sound or
is
distorted
• The audio cables aren’t connected
correctly.
• The volume is set to the minimum
level.
• The sound is switched OFF.
• Turn up the volume.
• Press MUTE on the remote control to switch
on the sound. Press PLAY/PAUSE.
Plus speakers
produce
humming sound
• Signal lines from source device to Plus
speakers are too long.
• Signal line used is not fault-protected
or the
protection has been damaged
(defective).
• Ground loop (ripple pickup) generated.
• Another piece of equipment on the
same circuit has no interference
suppression (e.g. fridge).
• Use shorter signal line.
• Change signal line for a fault-protected line.
• A ground loop can be generated when two or
more devices connected via a signal line
(synch) are plugged into separate sockets (e.
g. amplifier
and computer). Plug all devices connected to
the
Plus speakers into a multiple socket output
using
safety plugs.
• Switch off possible sources of interference to
test; unplug the device concerned to see if the
humming noise disappears or connect the
source of interference to a different circuit.
(Where
necessary take advice from your electrician).
Insert
a special “ferrite common mode filter” (available
from specialist retailers) between the amplifier
and
the Plus speakers to eliminate the humming.
Turn
the power plug round to reduce the so-called
ripple
voltage (particularly important if the source
device
is not earthed).
The remote
control does not
function
• There is no battery in the remote
control.
• The batteries are flat.
• The remote control isn’t pointed to the
remote sensor.
• The remote control is out of operating
range.
• The unit is turned Off.
• Install two AAA batteries into remote control.
• Replace the batteries with new ones.
• Make sure that the remote control is pointed
to the
remote control sensor.
• Make sure the remote control is within the
operating area.
• Switch Off the unit and disconnect it from the
AC
outlet. Then power it On again.
No playback via
Bluetooth.
• There is no connection between the
Plus
speakers and the Bluetooth end device.
• The Bluetooth end device is paired but
no
playback takes place.
• Connect your Bluetooth end device as
described (refer to your Bluetooth device user
manual).
• The Bluetooth end device must be connected
again.
»You are out of range.
»Set the volume on the mobile end device to
maximum
»Increase the volume of the Plus speakers.
»Ensure that interference sources like a WLAN
router or laptop are not set up in direct
proximity of the Plus speakers.
»Concurrent operation of WLAN and Bluetooth
from a Bluetooth end device is not possible
without interferences in most cases. (Disable
WLAN at your mobile device.)
