- While holding CLOCK, press the HOUR button repeatedly to set the current hour.
- While holding CLOCK, press the MIN button repeatedly to set the current minute.
- Release the CLOCK button. The current time is now set.
5. Operating Instructions
5.1 Programming ON/OFF Times
The timer allows for up to 8 distinct ON/OFF programs. Each program consists of an ON time and an OFF time.

5.3 Random Function
The random function provides a security feature by switching the connected appliance ON and OFF at irregular intervals (2 to 30 minutes delay) around the programmed times. This can simulate presence when you are away.
