Scroll back.

 Use the scroll back (rapid count down) effect when 

changing from “9” to “0”.

“1” = enable

“0” = disable

15

Red Channel Intensity.

 Sets the maximum intensity of the red 

channel back light. This will be dimmed according to the display 
dimming.

Default: 255

Max: 255
Min: 0

16

Green Channel Intensity.

 Sets the maximum intensity of the green

channel back light. This will be dimmed according to the display 

dimming.

Default: 255
Max: 255

Min: 0

17

Blue Channel Intensity.

 Sets the maximum intensity of the blue 

channel back light. This will be dimmed according to the display 
dimming.

Default: 255

Max: 255
Min: 0

18

Current case temperature.

 Show the current temperature inside 

the case (used as part of the temperature compensation for the 

clock crystal).

19

Clock version.

 Show the clock software version. In this version, will 

show “0006”.

20

Digit Test.

 Will roll through all digits on all locations to check that 

the display is healthy.

Display Blanking Mode

During display blanking mode, the “tick” LED will continue to pulse at low intensity, telling you that the 
clock is still running. In order to display the time, just press the button, and the time will be displayed.

If you want to enable the display for the rest of the day, do a long press of the button.

Tube Healing Mode

After a long period of time, tube filaments which are not often used (e.g. the “9” on the tens of hours or 
minutes) can get dim, despite the ACP that is regularly done.

If you make a “super-long” press of the button (more than 8 seconds), the clock will enter filament healing 
mode. All the power will be placed through a single filament of a single digit to clean it. A short press will 
change the selected filament.

Another super-long press or cycling through all the filaments will return the clock to normal.

Caution!

 Don't leave a single filament in this state for an extended period of time. It is a harsh process, 

and may damage the tube if you leave it in this mode for too long. Normally a few minutes will restore the 
cathode digit.

Factory Reset

To reset the clock back to initial settings, hold down the button while powering on and hold for at least 3 
seconds. The “tick” LED will flash 10 times to signal that the reset has been done.

Everything will be reset back to the factory default state.
