5.3 Memory, Power and Settings Management
All user entered changes to settings on the E4 XLS, as well as Service Mode data, are saved in FLASH memory.
They are therefore preserved in the event of battery failure or removal, with the exception of time and date (see
paragraph below). If you wish to reset the pipette back to factory settings, open the battery door. Using a clean
pipette tip, gently press and hold the reset button (see illustration below) for about 7 seconds. The unit will
beep, a splash screen will appear, and a “Memory Clear” warning will be displayed. Press the left softkey to
continue. This reset will NOT remove service data from the pipette.

The real-time clock, which keeps track of time and date, requires a continuous source of power. If the main
Li-Ion battery fails or is removed, and no external power source is applied (such as wall power or rapid charge
stand) the clock runs off a back-up coin cell battery. This battery will keep the clock running for about 90-120
days. If the coin cell battery drains completely, a notice will remind you to reset the time and date after power
is restored to the unit. A new coin cell battery will be needed to provide back -up power for the clock if desired.
