How To Use Your Device
Turn On & Off
Remove devices from case to turn on
Place back on case to turn off
❈ Remove the hearing aids from the charging case - they will turn ON automatically (indicator lights flash blue)
❈ The hearing aids enter into hearing aid mode automatically after being turned on.
❈ Place the hearing aids back into the charging case - the lights will flash blue three times and the devices will shut off automatically and begin charging (if the case is sufficiently charged or plugged into a power source). The lights on the devices will be solid orange (indicating charging).
To connect via Bluetooth (first time pairing):
❈ Remove BOTH Left & Right devices (both must be charged) from the Charging Case
❈ Be sure Bluetooth is enabled on your phone. Go to the Bluetooth setting on your phone and select “Pair New Device” (wording on your particular phone may vary slightly)
❈ Search for the Bluetooth identifier of your device (“Smart Buds”) and select it to pair (connect) - this may take up to 2 minutes
❈ Be sure to accept any prompts given regarding connecting the device to your phone
❈ After successful connection, the blue light on the device will flash once every six seconds instead of rapid blinking
Note: The above pairing only needs to be done one time with your phone. After that, as long as your phone is nearby and Bluetooth is enabled, the hearing aids will automatically reconnect when taken out of the charging case.
❈ There are 3 ways to disconnect Bluetooth
1. Turn OFF the devices by returning them to the Charging Case
2. Long press either the R or L buttons on the devices for 3 seconds (You will hear “Power Off” in your earpiece) to turn them off. Another 3 second long press will turn them back on (You will hear “Power On” in your earpiece)
3. Turn OFF Bluetooth on your phone. This will immediately disconnect your hearing aids from the phone. (You will hear “Disconnected” in your earpiece) In this case, to reconnect, simply turn Bluetooth back on in the phone.
