• Turn the mounting brackets on the built-in loudspeaker inwards to the stop. Then insert the speaker into
the assembly opening (fig. 3).
• Fasten the loudspeaker by fastening the screws on the mounting bracket clockwise. When this is done,
the mounting bracket will automatically turn outwards until it meets the stop.
• Do not replace the loudspeaker protective grid on the loudspeaker enclosure (fig. 5).
Maintenance and Cleaning
The built-in loudspeaker is maintenance-free. The surface of the device should only be cleaned with a slightly damp cloth or a dry brush. Never use aggressive cleaning agents or chemical solutions since these might
damage the surface of the casing or impair the operation.
Disposal
Please dispose of the device when it is no longer of use, according to the current statutory
requirements!

Installation and Connection
Make sure that the mounting area can support the weight of the loudspeaker.
The loudspeaker is to be fixed firmly to prevent it from falling and thus to avoid the risk
of injuries.
Before cutting out the installation opening ensure that no electric cables, water pipe
or are similar are at risk of damage behind the mounting location.
Be sure to follow the safety instructions of the tool manufacturer when using tools to
install your speaker.
When connecting the device, make sure the connecting cables are not pinched or
damaged by sharp edges.
The connection may only be made to suitable loudspeaker outputs on audio devices.
Make sure that the data for impedance and/or load stated in the Technical Data table
are in agreement with the data for the connected amplifier. Otherwise, damage to the
loudspeaker or the amplifier can occur.
The amplifier to which the loudspeaker is to be connected must be disconnected from
the power supply while the connection is being made(unplug the power plug!).
• Make sure that the installation location has the necessary installation depth (see Technical Data).
• Saw out the installation opening (for diameter see Technical Data).
• Lay the loudspeaker cabling from your amplifier’s speaker output to the installation location.
• To mount the loudspeaker, first remove the protective grid from the speaker. To do this, turn the mounting bracket on the loudspeaker enclosure as far as it will go to the outside (fig. 1). Them push the mounting brackets down (fig. 2). By doing so the protective grid will be pushed out of the loudspeaker enclosure.
• Before final assembly, connect the loudspeaker to the amplifier. Connect the loudspeaker cables from the
amplifier directly to the flat plug contacts on the loudspeaker:
positive loudspeaker cable > red terminal clamp (+)
negative loudspeaker cable > black terminal clamp (-)
