If your hearing aids are TRUE bluetooth devices, then it will be listed front and center in the manual.
Just because it pairs with your cell phone, doesn't mean that they are bluetooth devices. The detailed explanation is the second post on page 1.
In most cases, hearing aids are not actually bluetooth devices. You have to buy a "bridge" device from your hearing aids manufacturer (such as the one listed on page 4).
Ask your audiologist for more information.
