I am having an issue and maybe somebody can give me some advice. My daughter who is 6 years old received Phonak Savia hearing aids 5 years ago and we now use an integrated boot which functions wonderfully. She is in the process of getting a cochlear implant for her right ear, and is profound in her left ear. We use her fm almost every waking minute of the day. It really helps her hear us, and she depends on it greatly. We will wear it most of the day, except when she will watch TV, when we will place the inspiro mic by the speak of the tv. It functions wonderfully. Recently her educational audiologist suggested it may be time to replace her aid in the near future. We purchased a Phonak Naida 5 hearing device, and her school district provided her with a integrated boot. We were all very excited to get the new product. When it arrived, she wore to school the first day and complained that the "fm turned off". It happened a few times during the day, then especially during music class. Her music teacher would put the fm near the singing children, or sing into the mic so that she can hear the words and join in. It would turn of and on at a random time during this, which was very frustrating for her. We then tried to put the mic near the TV speak, and she would complain that the "fm turned off". We listened to the device with an otoscope and noticed the same thing. I contacted the hearing aid dispenser and they said it is probably the receiver. We had 2 receivers, so we switched it out and had the same issue. We then sent back the hearing aid and got a new one, but we had the same issues. This went on for 2 months. I was finally told by Phonak after 1 week of calling their support, speaking to multiple people, and mangers that the device is functioning as intended. It totally blows my mind, that Phonak intended their dynamic fm to constantly go into standby. If I am walking in a city street, or in a mall, if I am not constantly speaking to my daughter, her device will go into stand by after about 45 seconds, then turn back on at will, or when the program detects voice. I could see where it makes sense in theory, but it does not seem to be very responsive. For her it seems more frustrating that the volume fluctuates then if there was no fm system at all. It seems like it is intended for only a classroom use. Does anybody use the Dynamic FM, or have similar issues? Any advice what can be done to work around it? Any other manufacturer suggestions? Sorry for rambling, but I am very frustrated, angry, and annoyed that it took 2 months, countless hours on the phone, email, and 6 trips to the audiologist to figure it out. Phonak is very frustrating. They cannot discuss anything with me, are hesitant to give me answers on how their product functions, and never return calls, or messages.....
