6 Maintenance and Care
6.1 Cleaning
Use a non-abrasive cleaner on the outer glass case. Do not get any water inside the
clock!
The sides of the clock may be removed, but only with the clock unplugged! If the
inside of the case needs to be dusted, be very careful of the tubes, they are
delicate!
The round acrylic side shields (mounted on both sides of the printed circuit card)
can be removed. Remove the clear tape from the tabs, and gently pull the side
shields straight out. To install, push the side shields back on the tabs.
Note: Make sure to unplug the clock before cleaning. While operating high
voltage is present.
6.2 Use
The Nixie clock may be used indoors 50 Deg F. to 120 DegF. Higher or lower
temperatures will shorten the life of the tubes.
Never use outdoors!
