General Safety Instructions
• This device is only suitable for connection to a 12 V power supply.
• Use speakers with a suitable impedance (2-16 ohms, stereo).
• Do not connect active speakers (with built-in amplier).
• Do not mount the amplier in areas where it will be
• exposed to high temperatures (e.g. due to direct sunlight or
heating).
• exposed to rain or moisture.
• exposed to dust or dirt.
• If the car is parked in direct sunlight and the temperature in the car rises
considerably, allow it to cool down before use.
• When installing the device horizontally, make sure to cover the ribs with
a carpet or similar.
• If the power amplier is mounted too close to the car radio, interference
may occur. In this case, place the amplier further away from the radio.
• If the device is not supplied with power, check the connections.
• The amplier uses circuit protection to protect the transistors and
speakers in the event of a malfunction. Do not attempt to test the circuit
protection by covering the heat sink or electrically overloading the
device.
• Do not use the amplier with a weak car battery, as optimum
performance depends on a good power supply.
• Keep the volume at a moderate level so that you can still hear the
sounds outside your vehicle.
Circuit protection
This amplier is equipped with a protection that works in the following
cases:
• The device is overheated.
• Alternating current is generated.
• The loudspeaker connections have a short circuit.
The emergency stop light lights up when the device shuts down. If this
happens, switch o the connected device and nd out the reason for the
malfunction. If the amplier has overheated, wait until the device has cooled
down again before switching it on again.
