4. Installation
The Vehicle Unit will only operate on 12 V systems with negative earth
(Negative to body).
o Before starting installation, disconnect the vehicle battery and
observe other manufacturers safety instructions regarding
alarm systems, airbags or anti theft radio coding.
o If you want to install the Vehicle Unit in the passenger
compartment, make sure that all antenna cables and wiring is
protected from sharp edges and is routed in such a manner that
it will not be pinched.
o The GPS antenna should be positioned at a place where it will
have an unobstructed view of the sky. The ideal location is on
the inside of the windscreen. The aerial will not work if it is
placed beneath metal or metallic glass coatings.
o The SOS button should be installed at a place on the dashboard.
It should be hidden but easily accessed in emergency cases. To
avoid “false alarms” or unintended confusion with other
electronic control buttons, it should be placed separate from
dashboard controls and car audio devices.
o Do not connect the spare battery to the Vehicle Unit before you
have completed all electrical wiring and connections to the
device.
