The 'Status' LED in the battery control panel of the
CF 32 UP indicates the status of the external DC power supply when the battery switch is ON.
'Status' LED off: there is no power supply available and the internal battery is not being charged.
'Status' LED on: the external DC supply has enough voltage to keep both the cooler working and the internal battery charged.
'Status' LED flashing: the voltage of the DC power supply is too low to charge the battery.
The 'Status' LED is always off when the battery switch is OFF.
