Alarm and Time setting Mode
Alarm and time setting mode works identically, see the previous second for how to enter each mode.
When you enter alarm or time setting mode the current alarm setting or time setting will show up in the display. The first two digits will blink.
While the two first digits are blinking, rotate the encoder to set hours. Once you are finished, press the button. The two last digits will start blinking.
While the two last digits are blinking, rotate the encoder to set minutes. Once you are finished, press the button. The display will now show seconds blinking.
While the seconds are blinking (two last digits with nothing shown for the two first digits), rotate the encoder to set seconds. Once you are finished, press the button.
The display will now remember your alarm or time setting and return to normal operation.
The menu system is used to set various minor options for the clock.
Since the clock can only display digits, the menu uses numbers to indicate options.
Each menu item is numbered, starting from 1. The two leftmost digits are used to indicate each menu item number.
For each menu item, the selections are numbered, refer to each menu item below for details. The two rightmost digits are used to indicate the menu item.
Menu item 1 - 12/24 time
Rotate the encoder knob to select between 12 and 24 hour time viewing.
Keep the following in mind when the clock is in 12 hour mode:
- The right orange indicator LED will be used to indicate AM/PM. It will light up when it is PM.
- Setting time and alarm is always done using 24-time. For example, to set the time to 4PM, set it to 16:00.
Menu item 2 - Colon indicator
Option 0 - always off Option 1 (default) - always on) Option 2 - blinking
Menu item 3 - Leading zeros (show 0 before hours smaller than 10)

Menu item 6 - Cathode Anti Poisoning Feature
When nixie tubes are set to display the same number for a long period of time there is a chance of display damage (referred to as cathode poisoning). The chance of this happening is low for this clock since it uses multiplexing meaning that only one digit is ever turned on at a time.
