the CHARGING STATUS LED is blinking yellow.
Battery Replacement A replacement of the battery is absolutely necessary when the battery
reaches 40% full rated capacity of the 100% design capacity of the
battery pack. Then the system message REPLACE BATTERY is
displayed in the STATUS MESSAGE line. The Battery Service
Information Window in the Battery Service Menu shows the actual
FULL/NEW ratio in percent. If the usage of the Dash 2000 requires a
replacement because the FULL/NEW ratio of 40% is not acceptable then
it is up to the user to replace the battery earlier.
Follow this procedure to replace a defective battery pack in the monitor.
