Hi Dadybob

there is no time limit for the 660, you can leave it on as long as you like I
wolud do a test period with you being awake and run it for at least an hour to
see what happens first. If you strap it on try not to cover it completely with
cloth or if you do see how warm it gets after about an hour before sleeping with
it.

Take care,
V
