	Settings	Description
FL/EQU
-	Function	- This button is used to manually select SMR into float or equalize state.
HVSD RST
-	Function	- When SMRs shut down resulting from DC high voltage. This button is
		used to reset alarm state.
SMR RST
-	Function	System will detect RFA warning when SMRs are vacant or turned off.
		However, if the button is pushed at this time, the system will stop
		sending the warning.
Voltage/Current
-	Function	This button is used to change the voltage or current of LED display.

Notice: When SMR turn off , the system will detect RFA warning in ES48/90-JFAxx. When SMR vacant , the system will detect RFA warning in other system.
