Important Notes

•Choose a suitable location for your Soundsystem, that neither the driver’s field of vision nor the security of the inmates will be affected. This stands also for Airbag-Zones and Safety Belts. The permanent temperature of the location should not be lower than 5°C and not higher than 50°C. Protect the device from moisture and humidity.

•Ensure that your Soundsystem will not loose during the drive and hurt someone in the passenger cabin. It is recommended, that you mount the Soundsystem with suitable belts or any other mounting solutions in the trunk area.

•Please observe that you don’t damage any serial components of your vehicle (Airbags, Wires, Gastank etc.) during the installation of your Soundsystem by drilling or any other operations.

•The Soundsystem is designed for a 12-14 VDC operation with negative ground. Please also observe the page “Electrical Connections”.

•For your personal concerns you should choose a appropriate sound level for the Soundsystem, that neither the roadworthy of the driver nor his concentration will be disturbed, that he is able to notice possible traffic noises and acoustical warning signals.

•Modern Car Audio Soundsystems provide very high acoustic pressure beyond the

100 dB mark. Please observe in this case, that permanent use of high sound levels may get damage your ability of hearing.

•Follow by any means the installation instructions on the following pages. Faulty installed and connected devices may get damage the vehicle and the device permanently.

•In the case of a malfunction, please observe page “Trouble Shooting”!

•Please keep this Owner’s Manual for later purposes!
