Locate Power Source for MicroMax GPS350
1Determine how to power the MicroMax GPS350 using one
of the following sources:
1
Tap Change Bar
aRectifier — with power turned on to the rectifier, use a
voltmeter to locate a power source across any two
available AC taps. The MicroMax GPS350 requires 8 - 42
V AC.
bA 120 V AC convenience outlet with the 12 V DC wall
adapter.
cA DC source, such as a 10 - 60 V DC battery.
2Turn off rectifier power.
