Will the RMP alarm if the power base batteries are low?

How do I know the voltage of the powerbase batteries?

What is “battery maintenance mode”?

It's the trickle charge portion of the battery charging cycle. Note: NiMH batteries will stay in continuous trickle charge mode after fast charge and cell balancing mode.

That light (with the exclamation point above it) will be green when the unit is powered on without error conditions. It will be red if: - The e-stop clip is not engaged on the switch and power is turned on - There is insufficient UI battery pack charge - There is a problem detected within powerbase
