I got this from stoves customer service dept when my clock was telling the wrong time.
Press the rotary control knob to switch on the appliance
Touch and hold (for 10 seconds) the cook time icon located on the right hand side of the timer display. The icon will light once activated
The YEAR will then appear in the left hand display, turn the control knob until the correct year is set.
CAL will be shown on the left hand display, turn the control knob until the month is correct
The word DAY will appear on the left hand display, set day of the week by turning the control knob using the following codes
00 – Sunday
01 – Monday
02 – Tuesday
03 – Wednesday
04 – Thursday
05 – Friday
06 – Saturday
DATE will appear on the left hand display, turn the control knob to set the correct date, indicator will flash until stored
Hour will appear on the left hand display, turn the control knob to set the correct hour, indicator will flash until stored
Set minutes. Indicator will flash until stored.
