You can activate Timer Mode (countdown or cook timer) by clicking 
button on toolbar. The following window will appear:
Relative Time. Input the target time as relative when you know the length of the interval. For example, 40 minutes for a pie to get ready.
Absolute Time. Use this input field if you know the time when you need to be notified, e.g. TV show at 10 pm.
The value of absolute time is automatically recalculated as you enter relative time and vice versa.
Voice Synthesis. These settings are automatically obtained from the Settings window. However, you can specify different values for current timer. Refer to the Settings topic for details.
Click OK to start the timer.
Tip: You can switch your PC to standby mode while the timer is active. You computer will be automatically resumed from any sleep mode (S1, S3 or even S4) when the time is up.
