POWER SUPPLY AND TURN-ON-CONNECTION
INTERCONNECTION
INSTALLATION
The power wiring which is usually installed in on-board car networks is not sufficient for demands of this de-
vice. Make sure that the power wires to GND and to the +12 V terminal has been sufficiently specified. A cable
crosssection of at least 10 mm
2
must be used to connect the battery to the terminals of the device.
First connect the GND terminal (Fig. 1, 13) of the device to an appropriate ground connection at the chassis.
To ensure a good connection, residue dirt and dust from the connection point. A loose connection may cause
malfunctions or interferences noise and distortion.
Then connect the +12 V terminal (Fig. 1, 12) of the device with the battery by using an appropriate cable in-
cluding an in-line fuse (Fig. 1, 14). This fuse should be located very close to the battery (Fig. 1, 15); for safety
reasons not more than 30 cm away. Only insert the fuse when the installation, including the connection of the
loudspeakers, has been accomplished.
Then connect the remote turn-on-wire from the head unit (Fig. 1, 11) with the device‘s REMOTE terminal. A
cable with a cross-section of 0.5 mm
2
is adequate.
1. Mount the device in the car as shown below.
2. Avoid any damage or removing of the components of the vehicle like wires, cables, board computer, seat
belts, gastank or the like.
AUDIO SIGNAL CABLES
When installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the device
(Fig. 1, 8), the audio and power supply cables should, if possible, not be routed along the same side of the
vehicle. We recommend a separated installation, e.g. routing the power cable through the cable channel on the
left side and the audio cables through the cable channel on the right side or vice versa. This prevents interfe-
rences due to crosstalk into the audio signal.
PROTECTION CIRCUIT
If the POWER LED (Fig. 1, 1) lits up blue, the device is in normal operation. If the PROTECT LED (Fig. 1, 1)
lits up red, the device is overheated. If this events, the internal built-in protection circuit shuts down the device
automatically. The device should work again properly after cooling down.
