Configuration Terms:
In-Band
: DVR-LX operates in the same frequency band as a system frequency band.
Cross-Band
: DVR-LX operates in a different frequency band than all of the system
frequency bands.
Stacked
: DVR-LX components are stacked one on top of the other which requires more
height for installation.
Flat
: DVR-LX components are provided individually allowing for a lower profile
installation.
Cautionary Notes & Considerations
CABLE LENGTHS:
Unless special cabling length is specified upon placing an order,
the DVR-LX is shipped with a standard 3ft-long interconnect cable between the MSU
and DVR-LX.
GROUND POLARITY:
The DVR operates only in negative ground, +12VDC electrical
systems. Before starting the installation, make sure that the ground polarity of the
vehicle is correct. Accidentally reversing the polarity will not damage the DVR but will
cause the cable fuse to blow. Futurecom recommends installation of voltage surge
protection to protect the car electronics to prevent spikes in the supply voltage.
(fuse is 7A, 0.25"x1.25", fast-acting fuse)
VEHICLE USER MANUAL:
Before installing any electrical equipment, check the
vehicle manufacturer’s User Manual.
