Connect CallFinder to Power
Insert the 9 Vdc power connector into the CallFinder's power
receptacle and fasten it with the lock nut. Connect the female
end of the AC cord to the power block. Then plug the AC cord
into the power outlet.
Caution: Use only the 9 Vdc power transformer supplied with
the CallFinder. Use of any other transformer voids
the warranty and can damage the CallFinder.
