panel. The button must be held for a few seconds since there is a delay in
power on. You will see the power LED turn on and the display will show

The Z-Xtreme supports both internal and external power sources.
If using internal power, remove the battery and press the power level indi-
cator button. If low, replace battery with a good one and turn on the
receiver.
If using external power, check to ensure the power cable is properly con-
nected to both the battery and the receiver.
If the cable is properly connected, check the power level of the external
power source. If low, replace the battery with a good one and turn on the
receiver.
If external power source is good and the cable is connected to both the
receiver and the power source, there may be a problem with the cable. If
available, try a different power cable. If the new cable works, the old cable
is malfunctioning. Call your local dealer or Ashtech customer support for
assistance.
