Alpha-numeric keys
This array of keys permits entering numbers and letters into the Gene Pulser
Xcell. Pressing the Shift key toggles between alphabetic and numeric input. To
type an alphabetic character, press the Shift key to enter alpha mode, then
press the key with the appropriate letter. To type an a, press the 2 key once; to
type a b, press the 2 key twice; to type a c, press the 2 key three times. To use
the same key twice, for example to type a then b, advance the cursor using
the Right Arrow Key. The firmware on Gene Pulser Xcell will automatically
change between alpha and numeric input depending on the parameter being
entered. In Protocol screens and Directory screens where a two-digit entry
must be made, the second digit must be entered within 2 seconds of the first
entry, otherwise the screen will default to the single-digit entry.

Results in discharging a pulse. During this time “Pulsing” is shown on the LCD
display. A tone sounds to indicate that the pulse has been delivered. When

connected and the lid is closed. Otherwise, it is discharged safely within the
instrument.
