switch in the far-right position, the
TWR-RF-SNAP can also be powered
by inserting the module into the Tower
System and providing power via the
TWR-ELEVorMCUmodule.Optionally,
with the power switch in the far-left
position, the TWR-RF-SNAP can be
powered via the battery connector in a
stand-alone configuration only.
