Consult an authorized Blaupunkt dealer for installation or reparation. Read the manual carefully before operating the device for the first time.
Safety Notes Ensure to follow below safety notes during installation and wiring connection: -
· Disconnect the negative terminal of the battery. Refer to the safety notes of the vehicle manufacturer.
· Ensure positions of the holes are nowhere near the vehicle component to avoid any damage during drilling.
· Ensure cross section of the cable is no less than 2.5mm2 if the positive and negative cables are too long.
· Incorrect installation may result in malfunction of the device or the car sound system.
Installation and Connection Instructions
· Select a dry and well-ventilated location to install the device.
· The device must not be installed in overly exposed location such on therear shelf, rear seat etc.
· The installation location must be suitable for screw holes and have stable ground support.
Integrated Fuse The integrated fuse in the device protects the output voltage and the entire electrical system in case of malfunction. Do not replace damaged fuse with higher current.
Disclaimer In no event shall Blaupunkt be liable for any direct, indirect, punitive, incidental, special consequential damages to property or life and whatsoever arising out of or connected with the use or misuse of our products.
