Case Power Sources
The GSA Unit can operate from a variety of power sources: external A/C power, external D/C
power, and from internal batteries. When connecting to or disconnecting from an external
power source, you may hear a click from inside the case. This is caused by relays within the
unit and is normal.
CAUTION: THE EQUIPMENT COVERS INSIDE THE GSA UNIT
SHOULD NOT BE OPENED! 
Hazardous voltages may be present at any time
and there are no field serviceable components inside.
CAUTION: Most power sources and components come with a panel or label
stating their power ranges. If these ranges are exceeded, then there is a very
strong potential to cause irreparable damage to the case and/or component
causing it to malfunction or not to work at all. Therefore do not push these
sources beyond their designated power ranges.
