Our new on-board phonesystem OE6300KB-HSU has been developed for smaller vehicles and special applications (VIP buses). The freely available Nokia phone model HSU -4 will be plugged into the socket provided in our control electronics. The control unit will be supplied with microphone and speaker and allows hands-free operation on the driver's seat.


The on-board telephone system is designed for an operating voltage of 12 volts. Of course,a version for 24 volt can also be ordered.

Thanks to the processor control we limit the operation to a few operating steps because most functions are controlled automatically.

The complete set comes with the Nokia phone HSU-4. As all our products, this board telephone system is also characterised by an excellent voice quality.
