I want to adjust timer.

I've tried pulling various sides of it, i know there are clips somewhere, I just don't want to break it.

if there is a technique or nack to doing it please let me know

thank you

The pictures seem to suggest clips top & bottom. I'd try to lever the cover off near those clips.
