• The head sets hanging on the wall are turned off and should be turned off when replaced in the rack.
• The loop only works in the choir loft and in the sanctuary in front of the pulpit. (Unfortunately you can't test one while standing in the narthex.)
• They work best when used in place of hearing aids, but will also work when worn right over hearing aids.
• Hearing aids with tele-coil receptors work better than these head sets. (Your audiologist can retro-fit your hearing aids with tele-coils if you don't already have them.)
