Technology to extrapolate and supplement with  
proprietary algorithm, the high-frequency range  
that is cut off when encoding at low bit rate (less  
than 128Kbps, Sampling frequency is 44.1kHz).  
Supplementing is optimized by compression

Accessories/ Installation Procedure  
with the ignition, connect the ignition wire to a power  
source that can be turned on and off with the ignition key.  
Use a commercially available conversion connector if the  
connector does not fit in the vehicle connector.  
Insulate unconnected wires with vinyl tape or other similar  
material. To prevent a short circuit, do not remove the caps  
on the ends of the unconnected wires or the terminals.  
If the console has a lid, make sure to install the unit so that  
the faceplate will not hit the lid when closing and opening.  
If the fuse blows, first make sure the wires aren’t touching  
to cause a short circuit, then replace the old fuse with one  
with the same rating.
