HR strap from Garmin 305 won't work with my 705?

Why won’t my 705 pick up the HR strap from my 305? I was hoping to use both computers racing and don’t want to change straps. What’s the deal?

have you put the strap on and did a rescan for it? if it doesn’t pick up put some water on your skin, after that it should work fine, i use both of mine interchangeable.

Maybe I need to try the rescan. I did have it wet.
