When the hearing aids are in Bluetooth mode, they will only get about 5-6 hours of working time.
However, if you take them out of Bluetooth mode by following the instructions below, you should get up to 15 hours of use.
- Go to Bluetooth Settings on your phone
- Look for "5118L"
- Tap the "i" (information) icon (if using iPhone)
- Tap "Forget This Device"
- Restart your phone
Then when using the hearing aids, push and hold the top function button for 3 seconds to select from the 4 pre-set sound modes. Tinnitus mode is the fourth mode.
