The device you have just purchased is equipped with state-of-the-art technology and is safe to
operate. Nevertheless, problems or malfunctions may occur.
Before contacting a service technician, refer to the following possible solutions:
Distorted sound or no sound is audible
› Check if everything has been connected properly.
› Check if all devices in the playback chain have been turned on and/or are connected.
› Check if the right input has been selected.
› Check the volume control’s position.
The remote control is not working
› Check if the batteries have been inserted correctly.
› If batteries are empty, replace them with new ones.
› Point the remote control to the remote sensor and press to operate.
› Remove any objects found between the remote control and the remote sensor.
› Make sure the distance between the remote control and the device does not exceed 8 m.
Buttons do not function (on the device and/or remote control)
› Turn the device off and then on again. As an alternative, turn the device off, unplug it from the
power outlet and plug in again. (The device may also not be functioning due to a stroke of light-
ning, static electricity or other external factors.).
A connected USB medium is not working
› The USB-port does not provide the power needed for using the external media, for example a
hard drive. Look up the instruction manual of the connected medium.
Any repairs other than those mentioned above are to be carried out solely by an aut-
horized technician.
Maintenance
› Carry out a technical safety inspection on a regular basis, e.g. check if the power cable or
housing may have become damaged.
› If there is reason to believe that the device can no longer be operated safely, then disconnect it
immediately from the power supply and secure it against any unintentional operation. Carefully
remove the power cable plug from the wall outlet and where applicable switch off the corre-
sponding circuit breaker first.
› It can be assumed that safe operation is no longer possible, if:
› there is visible damage to the device or power cable,
› the device no longer works,
› it has been stored for a longer period of time under unfavorable conditions
› or exposed to rigorous transport conditions.
› Always adhere to the following safety instructions before cleaning or servicing the device:
Live parts may be exposed, if the covering is opened or parts are removed.
The device must be disconnected from the power supply source prior to service, main-
tenance or repairs.
› Capacitors within the device may still carry voltage even though they have been disconnected
from all power supply sources.
› Repairs are only to be carried out by qualified personnel, who are familiar with the hazards in-
volved and the relevant regulations.
Transporting or sending the device
› Please retain the original box and the packaging material in case you need to transport or send
the device out for maintenance at a later date. Please note that the device should be repacked
in the original packaging. The box and packaging have been especially developed for this device
in order to protect it during transport and against damage. Retain this instruction manual for
future reference and where required pass it along with the device if handed over to a third party.
Keeping the external case clean
› Never use volatile fluids near the device, as for example insect spray. Avoid letting the device
come in contact with rubber or plastic products for longer periods of time. These could other-
wise leave marks behind.
