The Nano SX2000 behind-the-ear model is a battery-operated style hearing aid designed to reduce tinnitus, (sound heard in the absence of external noise), by producing a low-level static sound to provide an alternate sound to listen to besides head noise. Similar to our other behind-the-ear hearing aids, every morning before use check for wax clogs in tubing and domes by removing them. Push the nylon monofilament through the slim tube starting at the end that connects to the hearing aid. Clean the end with a tissue when it pokes through. Brush the dome with the cleaning brush. Refer to the “Cleaning Your Hearing Aids” blog on our website for further information.

The SX2000 hearing aid runs on a size 312 battery. Remove the sticker from a zinc-air battery and allow air to load into it for 5 minutes to achieve the best battery life. Follow the instructions in the manual for battery placement, thin tube use, and dome use, or visit our blog library on the Nano website.

If you get some whistling after you put the hearing aids in your ears the first thing is to verify the tubings and domes are clean. When the hearing aid is working correctly it should whistle when it is cupped in your hand. When you cover the clean dome sound opening and cup the hearing aid there should be no feedback. Bring it up to your ear or someone else’s ear. If there is feedback then there is a leakage in the system, possibly caused by a hole in the tubing. Try a new tubing to confirm that the feedback is eliminated. If you experience feedback when the hearing aid is in your ear you may need a different size dome. Refer to the “Choosing the Correct Dome Size for Behind-the-Ear Models” blog on our website.

The adjustments possible for this hearing aid are volume increase or decrease, mode change, and modification of the sound by changing from an open to a closed dome. Different combinations of adjustments will modify the sound of the hearing aids for comfortable listening.
