Warning!
• The device is only intended for operation with a built-in battery, which
must not be replaced by the user and whose type is specified in the
technical information of the operating instructions.
• Ensure that all cable connections are securely and correctly connec-
ted. Do not insert any conductive objects into the device connectors.
• When plugging and unplugging connectors, pull the connections by
the connectors, never pull the connection by the cable itself.

whistle in the ears or other discomfort, stop using the device.
• Never overload the device beyond the limits specified in the technical
data.
• If you notice any abnormal effects (sounds, odors, smoke, ...) while
using the unit, turn off the unit immediately and unplug it from the
wall socket. Have the device checked by a specialist garage.
• Do not store the device in places subject to high or low temperatures
to prevent deformation and disturbance of its covers and parts.
