The AL1 determines its position by communicating with the Global Positioning Satellites through GPS
antenna. The location where the AL1 is installed will have great effect in the overall performance of the GPS
receiver. The AL1 device has an internal GPS antenna but it is not a water proof design. Therefore, it shall not
be installed outside of cabin or with the possibility of being splashed by water or rain . Ideally the label of AL1
should facing up (towards the sky) after the installation, such that the top of the device has a clear view of the
sky. Mounting in this orientation provides optimum GPS signal reception.
Please note that the following interior conditions may cause bad GPS reception of AL1:
 Your vehicle has metallic window tint
 Your vehicle has a windshield mounted radio antenna
 Your vehicle has a solar reflective window
This face towards the sky
