Display Blanking Mode
During display blanking mode the tubes will be off depending on the display blanking settings,
but the LEDs will continue to work as usual, telling you that the clock is still running.
You can configure the display to blank at weekends, during week days, always or never (the
default). Also you are able to define hours during which to blank. For example I have a setting
saying that the clock is blanked on weekdays between 7am and 4 pm, while I am out at work.
At weekends, the display runs all the time.
You are also able to override the blanking. Press the button while the clock is blanked, and the
display will come on again. Pressing the button will display the time for about a minute (60
seconds, but the display is only blanked on the minute change).
If you press the button multiple times within 5 seconds, the blanking will stay off for longer
periods:
•
1 Press: 10 seconds
•
2 Presses: 1 hour
•
3 Presses: 4 hours
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 “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
seconds minutes will restore the cathode digit.
Normally you will not need to use this mode! It is only there for tubes that are already in
trouble.
Don’t make a habit of using this mode!
Factory Reset
To reset the clock back to initial settings, hold down the button while powering on. The LEDs
will rapidly flash some colours to signal that the reset has been done.
Everything will be reset back to the factory default state, and the clock will go back to “First
Start Mode”.
External power supply
The perfect voltage for the external power supply is 7.5V or 9V DC. You can use 12V DC.
If you use more than 12V be aware that you might have to provide a heat sink for the power
components and adjust the HV voltage generation. It is not advised to use more than 12V.
The absolute maximum permissible is 16V DC. Higher voltages than this will surely damage the
clock.
