Anti-cathode poisoning mode helps prevent a condition in Nixie
tubes where the cathodes (the individual digits) that aren't used
often will be 'poisoned'. This is where deposits build up on the
digits. When these deposits are thick enough, parts of the digit will
not light up. This mode will cycle all the tubes through all the
digits at full brightness 4 times, exercising the digits, preventing
cathode poisoning.

'23', ‘44’, ‘55’ will be displayed in the 2
rightmost digits, with the colon on. To change the enable time,
press the black function button (left side). Holding the function
button on will quickly cycle through the hours (0-23, 44, 55). Press
the red mode button when the desired anti-cathode poisoning
enable time is displayed. The next option will be displayed.
To cancel the option function, press and hold the red mode button
until the display goes blank. Release the mode button and the clock
will go back to normal operation. Option 1 - 5 will still be saved,
but option 6 will not be saved.
