Power Supply Connector
Attach a power cable from Hand Held Products to this connector. The Mobile Base can be powered by an external DC
power source between 11 VDC to 48 VDC. To run on vehicle power, you can use the 12 VDC cable or 24 VDC cable
option. The appropriate cable comes with the kit you ordered. The 12 VDC cable can be used with a cigarette lighter
outlet. The 24 VDC, pigtail cable can be used to “hard-wire” into the vehicle power bus.
Verify that the power source is always within the specified range and observe correct input voltage polarity. An improper
input voltage range (above the 48 VDC maximum) or reverse polarity could damage the power conversion circuitry.
