hour guard

Any one using TS02 hour guard, i have started using one, but im finding the little instruction sheet a tad confusing, and i just cant work out how the daily rest is activated, thought it would be just press the daily rest button, but, no. nothing happens on mine might be broken im not sure, a little explanation would be great,
thanks guys. :blush:

To activate the rest period you must be in drive mode and keep the rest button pressed until it activates, I sure you will have done this ? So I am thinking your Hourguard is u/s.
