For installations where the LX60 is to be turned on/off, use the white wire
connected to Pin 3 in the DC cable. The LX60 is off when this pin is either
open-circuit or grounded, and on when this pin is connected to power. The
LX60 should not be turned off by simply disconnecting the power.
Pin 3 can be connected to the vehicle ignition or to an external switch.
Note: If you do not connect pin 3 to the ignition or other switch, you
MUST connect it to the positive terminal of your power supply or battery. If
you are using a Sierra Wireless AC adapter, the connection is inside the
cable.
