If your HDs aren't amplifying, even after changing your batteries, it's possible that it may be an issue with either the batteries that you currently have, how the batteries are inserted in your device/s, or in a worst-case scenario, it could be a malfunctioning device.
First, please make sure that you have the batteries connected and snapped down properly.
- Remove the comfort tip from the HD device before trying to attach the batteries. Once the comfort tip is removed you should be able to see two things on the devices: a white dot on the device that will align with the groove locks on top of the HD devices and hooks where the battery should go under.
- Place in the batteries by holding on to the small handle, and insert it nose down, under the hooks. Once attached, you'll need to snap in the batteries and bottom it out to the second latch to make sure it connects properly. This step requires a bit of finesse and can be a bit hard to snap in. Don’t be afraid to press hard on it to ensure it latches correctly for a snug fit.
It can take a few tries to get this correctly, but it gets easier once you get the hang of it. Just remember to make sure to lock the connection by pressing hard on it to snap it in place. There's 2 latches near the bottom of your device, where the batteries hook on to. It must be snapped down completely to be sure it connects properly.

If you’re still not able to turn it on or not getting any amplification, a good way to isolate where the issue is happening, is by plugging in your devices, like you're tuning them.
- So plug in and attach the USB device (rectangular device) to the USB port of your computer
- Attach the programming cable (USB 3.0 Micro-B / the odd shaped USB) to the iHear USB
- Insert the other end of the programming cable to the device/s, like how you insert the batteries
Once all components have been plugged in, the programming cable actually acts like a battery and should draw power from the USB port of your computer, and the devices should work (you don’t even need to open the Tuner). It's kind of like having wired hearing aids. From there you can test it to see if the amplification is working and see if you run into the same scenario after prolonged use (You can leave it on there and it'll stay powered on).
If the device/s are working without issue when plugged in the computer, that would indicate that the devices themselves are working properly, and isolate it being the battery that has the issue. At this point in time, try a new battery and if you can make sure that the batteries are snapped and bottom down to the second latch, to ensure a proper connection. If you're still running into the issue (after isolating on the computer) and using the new batteries, it’s highly likely that you have discharged batteries.
If they don’t turn on or are still having issues while plugged in the computer, it’s probably the device itself that has a problem; which we’ll definitely need to investigate and/or replace via RMA. Please contact Customer Support.
