7.3 First Tube Test
Insert the 6 tube cells into the main PCB, ensuring the tubes face
forwards (The switches are at the back).
Connect a 12V DC power supply (2.1mm central pin type, centre
positive) and power up.
The clock should start counting 0-9 repeatedly on all tubes. If this
does not happen, power off and check all tubes are connected
correctly. If the counting order is wrong, go back and repeat step
7.2.
Pressing ‘SET’ will exit the tube test mode with a bleep and the
clock will start time display.
Do not be tempted to press buttons without knowing the function.
If the clock bleeps, shows the time and is incrementing time, this is
sufficient at this stage. Power off and disconnect the power supply.
