6.2.1 System Power Supply
The RF320 radio should be connected to a DC power source of not less than 9
Vdc and not more than 17 Vdc with a capacity of 2 A. For optimal
performance, it is recommended that the supply voltage be maintained between
12.5 to 14.0 Vdc.
Due to the amperage needed for proper operation of the RF320
during transmission, a datalogger's SW12V should not be used to
power the radio. Using a datalogger's 12V to power the radio is
not recommended. NOTE
The radio is protected against accidental reversal of the input
voltage by an internal, resettable fuse. If a reversal of input
power has occurred, it will be necessary to disconnect the power
supply to reset the fuse. NOTE
