Anti-cathode poisoning mode (see section 5.1.12). Press either the

7.1.6
Decimal point of tube is faintly glowing
1)
Decimal point is glowing when display is off. This is normal,
especially visible on left most digit. This is a “pilot” decimal point,
and has a constant low current to speed up display time from off
display to a digit.
7.1.7
Tube(s) not working
1)
Display blank, see section 7.1.1.
2)
Tube(s) delay coming on when clock cold or in dark room. This is
normal for Nixie tubes – they need external energy to turn on. When
it is dark they may not come on right away. Once they warmup, they
should be ok.
3)
Parts of the digit do not show up. The tubes have Cathode Poisoning.
Make sure the Anti-Cathode poisoning function is enabled. If it does
not clear after a week or two, the clock will need servicing (new
tubes). Contact ColdWarCreations (
).
4)
A Nixie tube(s) does not light up; the clock will need servicing (new
tubes). Contact ColdWarCreations (
).
5)
If a tube is bad, Contact ColdWarCreations to have the tube replaced,
or (
) to purchase a tube. If you have your
own tube, the Cold War Creations website will have the latest
instructions for tube replacement.
