Steps to try in order
How to fix
Tubes are off
Press any button to wake the device from a
programmed off-time. If the tubes turn on, then the
clock was turned off automatically according to the
configured on-off timer
Connect your device to a PC and
refer to
disable the timer feature.
Press the
▼
button and observe if LEDs change. If so,
the USB voltage is too low to light the tubes.
Ensure that you are using the
supplied USB power adaptor.
Replacements can be ordered from
NIXlabs.
Unplug clock, wait a few seconds, and re-connect.
If the problem occurs frequently,
contact NIXlabs. You can force a
reset by pressing the red button
under the clock with a bent
paperclip (this clears time and
settings).
Ensure USB connector is firmly attached, that you are
using the supplied power adaptor and the outlet is
working. If still inoperable, try a different USB charger
such as those supplied with mobile phones.
If operation is normal with an
alternate power adaptor, then
order a replacement adaptor from
NIXlabs.
Tubes are dim
or
to set the tube brightness level and night-
detection threshold.
Try changing both day and night
tube brightness levels. If the clock
is using the night brightness value,
refer to
(or
) to set the
night-detection threshold.
Ensure you are using the supplied power adaptor and
that it is firmly attached, as brightness is automatically
reduced if the USB voltage drops too low.
Ensure you are using the supplied
USB power adaptor. Replacements
can be ordered from NIXlabs.
Display is
flashing on and
off
Ensure you are using the supplied power adaptor and
that it is firmly attached. If powered from a computer,
do not use unpowered USB hubs or extension cables.
Ensure you are using the supplied
USB power adaptor. Replacements
can be ordered from NIXlabs.
If powered from a computer, avoid
unpowered USB hubs.
Digit is not fully
lit, flickering or
has dark spots.
As the nixie tubes age, they may flicker or partially-
light if the brightness is set too low. Dark spots can be
caused by “cathode poisoning” which can be reduced
by using the anti-poisoning feature. If the tube
appears completely “off” it may have become
damaged (eg: crack in the glass).
Refer to
or
the tube brightness. You can force
the anti-poisoning sequence by
using the Web App. Also see
Maximising Tube Life.
Display and
LEDs are
brighter than
set level
Power supply voltage is too high. Ensure you are using
an appropriate power adaptor. If powered from a
computer, try a different port or USB hub.
