Nothing works

•  If running from an external power source, is the red External Power light on the

GSA Unit control panel lit? If not, the GSA Unit is not actually connected to
external power. Possible causes of this problem:

•  The A/C power cord is plugged into a power strip or plug that is not turned

on.

•  The D/C power cord is connected to a source, e.g., a cigarette lighter, which

requires the key in the vehicle to be turned on.

•  The power cord is not fully inserted into the socket or the power source has

a blown fuse or circuit breaker.

•  If the GSA Unit is running from internal battery power and the control panel

switch lights do not come on or are only dimly lit, the case batteries are probably
discharged.
