This platform relies on the Battery LED light blinking in an amber or white pattern to determine a failure as listed in the following table: Note: The blinking patterns consist of two numbers (representing the First Group: Amber blinks, Second Group: White blinks).First Group: The LED blinks 1 to 9 times followed by a brief pause with the LED off at an interval of 1.5 seconds. This is in Amber color.Second Group: The LED blinks 1 to 9 times that would then be followed by a longer pause before the next cycle starts again at an interval of 1.5 seconds. This is in White color.Example: No Memory detected (2,3). The battery LED blinks two times in Amber followed by a pause, and then blinks 3 times in White. The Battery LED will pause for 3 seconds before the next cycle repeats itself again.
