NOTE: When the start-up process is completed, if the Power LED does not flash – it
displays as a solid green or orange all the time – the start-up process was not
successful. In this case, disconnect the unit from the power supply and then
reconnect it.
NOTE: It is recommended that only vehicle installation specialist connect the unit to the

Connecting the Unit to the Vehicle Battery

(not supplied). This can be done in one of two ways:
• Connecting the unit directly to the battery and the ignition
• Connecting the unit to a power source in the vehicle that is only active when the ignition

powers up when the ignition is switched on. If the unit is connected directly to the battery, it
can be configured to operate only when the vehicle ignition is on or to shut down
automatically soon after the ignition is turned off. Otherwise, it will shut down automatically
when the ignition is turned off.
For testing and evaluation purposes, the unit can also be powered by connecting it to the
vehicle’s cigarette lighter, if the vehicle has one. This method connects the unit to the battery
and the ignition quickly and easily, but it is not normally suitable for permanent connections,
because it is difficult to install the unit and the wiring securely in appropriate locations when
this method is used.
