Using The Clock Button - Nixie Clock Wemos Series User Manual

Using the clock button

Normally the clock is in "Time Display Mode", which will show the time. If you press the button
for differing lengths, different things will happen.
"Short Press" (less than 1 second): A temporary display will be shown for 5 seconds. This is
useful if you want to know the date, for example. The options here are given in the section
"Temporary Display Mode"
"Medium Press" (more than 1 second): The clock will go into "Setting Mode" to allow you to
change settings. If you are connected to a network, you can change settings using a browser
which is much easier.
"Long Press" (more than 8 seconds): The clock will go into "Tube healing mode". Read the
section on "Tube healing Mode" before using this mode. This mode can damage your
tubes if you don't use it correctly!
