Setting the clock

[MadMax]

I don't think it's possible, this is all the manual has to say on setting the clock...

The digital clock indicates the time.

To adjust the clock, put the key in the “ON” position.

With tachometer—

Pushing the reset knob flashes the indicator for the hour and you can adjust the hour.
Press the reset knob until the desired hour will appear.
After 5 or more seconds pass without operating, the indicator for the minute flashes. Then you can adjust the minute.
Press the reset knob until the desired minute will appear.
After 5 or more seconds passes without operating, the indicator will return to the normal display.
If the electrical power source has been disconnected from the clock, the time display will automatically be set to 1:00 (one o’clock).
