To program the course, you will first need a portable power source. We like to use a small 12 volt, 1.3 amp sealed lead acid (SLA) rechargeable battery. Connect this to your power cable and plug it in to the unit. The unit will turn on automatically with the motion sensor.
The To The Green GPS Unit will take 3 to 5 minutes to locate and load the proper number of satellites the first time it is activated in a new location. Subsequent activations will take 1 to 2 minutes.
