There are two ways to change the volume of a phone call when using the Bluetooth hearing aids:

• Using the volume control buttons on the mobile phone to adjust the call volume
• The push button on the Bluetooth hearing aids themselves can be configured to adjust volume. If that is the case, during a call:
  • To make the call volume louder and to reduce the volume of the surrounding environment, use the push button on the right hearing aid   
  • To make the call volume lower and to increase the volume of the environment, use the push button on the left hearing aid

For further information regarding volume preferences, check the printed Getting Start Guide.
