Page 15: Using Your Personal Fm System With A Hearing Aid
SING ERSONAL If you have a hearing aid equipped with a Telecoil (T-Switch), you can use a Neckloop (NKL 003–children’s size, or NKL 001–adult’s size) to magnetically couple the signal from the PFM Receiver into your hearing aid. The Neckloop plugs into the earphone jack of the receiver. Turn the switch to the “T” position on your hearing aid and adjust the volume control on the receiver to a comfortable level. - Page 16 10. If you are still hearing interference on the Receivers, turn the Transmitter off and listen with a receiver. If you hear the interference with the Transmitter off, you need to change to a clear channel. See the re-tuning instructions. 11. If problems remain, contact your dealer for further help.
