Setting time is not in manual that we received, however, we did get a separate sheet:
Buttons top left-right are
A - Clock adjustment
B - Operating Mode selecting
C - Override
Buttons bottom left-right are:
D - -
E - Programmes
F - +
To set clock: 1 - Push A 2 - When the DAY and the CLOCK icons on the LCD are flashing use + and - (D and F). You should set the day of the week (1 = Monday, 7 = Sunday). To confirm the day press A. 3 - The HOUR and CLOCK are flashing use + and -. Confirm with A. 4 - MINUTES and CLOCK are flashing use + and -. Confirm with A.
My LCD is not working correctly, so I have to press the screen gently to see what icons are displaying. Annoying.
