The DSG Thresh x threshold is the % of SBS.RelativeStateOfCharge( ) or SBS.AbsoluteStateOfCharge( ) to
enable the respective LED.
The DSG Flash Alarm threshold is the % of SBS.RelativeStateOfCharge( ) or SBS.AbsoluteStateOfCharge( ) at
which the remaining active LEDs flash at a 50% duty-cycle rate of DF:LED Flash Rate.
If DF:Operation Cfg A [LEDRCA] AND SBS.BatteryStatus( ) [RCA] are set, the display flashes at the DF:LED
Flash Rate with a 50% duty cycle.
If DF:Operation Cfg A [LED1, LED0] = User, the User data flash percentages are used and the values are
defined within the range indicated in the Display Timing table.
When DF:Operation Cfg A [LEDRCA] = 0, the SBS.BatteryStatus( )[RCA] is ignored.

The CHG Thresh x threshold is the % of SBS.RelativeStateOfCharge( ) or SBS.AbsoluteStateOfCharge( ) to
enable the respective LED.
During charging the top LED segment flashs at the rate or DF:LED Blink Rate (eg: if
SBS.RelativeStateOfCharge( ) = 36% and 5 LEDs are being used then LED2 will blink).
The CHG Flash Alarm threshold is the % of SBS.RelativeStateOfCharge( ) or SBS.AbsoluteStateOfCharge( ) at
which the remaining active LEDs flash at the rate of DF:LED Flash Rate, with a 50% duty cycle.
If DF:Operation Cfg A [LEDRCA] AND SBS.BatteryStatus( ) [RCA] are set, the display flashes at the DF:LED
Flash Rate with a 50% duty cycle.
If DF:Operation Cfg A [LED1, LED0] = user, the user data flash percentages are used and the values are defined
within the range indicated in the Display Timing table.
