Try the following actions to resolve the issue. If the issue persists, proceed to the next troubleshooting step.

Try to duplicate the issue

Validate that you understand the symptoms being experienced. For example, make a phone call and change volume and audio settings to make sure the Bluetooth headset is functioning. Use the audio keys on the side of the BlackBerry smartphone to raise and lower the volume.

Verify that the Bluetooth headset is paired with the BlackBerry smartphone

You must pair a BlackBerry smartphone with a Bluetooth enabled device before you can connect to it. For more information about preparing the Bluetooth enabled device for pairing, see the documentation that came with the Bluetooth enabled device.

Pair BlackBerry smartphone with a Bluetooth enabled device

1. On the Home screen, click the connections area at the top of the screen, or click the Manage Connections icon.
2. Click Bluetooth Options > Add New Device > Search.
3. Click a Bluetooth enabled device.
4. If necessary, do one of the following:
• If the Bluetooth enabled device does not have a keyboard (for example, a wireless headset), on your BlackBerry device, type the pairing passkey that either appears on the Bluetooth enabled device or is provided in the documentation that came with the Bluetooth enabled device. The passkey is most often a numeric or alphanumeric code. Note: 0000 is often a common default passkey for Bluetooth devices.
• If the Bluetooth enabled device has a keyboard (for example, a laptop), type a pairing passkey of your choice on both devices.

Verify that the Bluetooth device is set as a trusted connection

You might experience issues if the Bluetooth device that is paired with the BlackBerry smartphone is not set as a trusted connection in the BlackBerry smartphone properties.

1. From the BlackBerry smartphone home screen, select the Options icon.
2. Select Bluetooth.
3. Highlight the Bluetooth paired device in the list that is experiencing this issue and press the Menu key.
4. Select Device Properties.
5. Set Trusted to Yes.

Test the Bluetooth headset

Remove the Bluetooth headset, and then test the audio functions. If the issue occurs only when using the Bluetooth headset, the issue might be with the headset and not the BlackBerry smartphone. In this case, contact the Bluetooth headset manufacturer for further technical support.

Inspect the earpiece jack

Inspect the earpiece jack for any damage. A part may have become dislodged in the earpiece jack, causing the audio problem.

Check audio settings

Check the volume settings and adjust as necessary.

You can also increase the default volume for calls. The higher the volume percentage, the louder the volume. To change the default volume for calls, complete the following steps:

For BlackBerry Device Software 4.5 to 5.0

1. In the phone application, press the Menu key.
2. Click Options.
3. Click General Options.
4. Change the Default Call Volume field.
5. Press the Menu key.
6. Click Save.

For BlackBerry Device Software 6.0

1. In the phone application, press the Menu key.
2. Click Options.
3. Click In-call Settings.
4. Change the Default Call Volume field.
5. Press the Menu key.
6. Click Save.

Improve sound quality for all calls

Note: You cannot change sound quality when you are using a Bluetooth ® enabled headset.
To improve sound quality, complete the following steps:

1. In the phone application, press the Menu key.
2. Click Options.
3. Click Enhanced Audio.
4. Change the Phone Call Audio or Headset Call Audio fields.
5. Press the Menu key.
6. Click Save.

Check the signal strength

You might experience issues with voice quality if you have low or intermittent signal strength. The signal strength of a BlackBerry smartphone should be between –40 and –100 dBms.

To check the signal strength of a BlackBerry smartphone, complete the following steps:

1. On the Home screen, click Options.
2. Click Status.
3. Check the Signal value. The value should be between –40 and –100.

Note: You can press and hold the Alt key, and then type "nmll" to change the signal indicator bars to the numerical value. Repeat this step to again display the signal strength bars.

If the signal strength is good, think where you were when you experienced the issue and if you noticed if the signal strength was low. In areas where signal strength weakens and causes the signal to become blocked by tall buildings, terrain, landscape, and physical distance, moving to an open area might help improve the voice quality.

Perform a Hard Reset

A hard reset is similar to restarting a computer that has stopped responding. A hard reset closes all running BlackBerry applications, restarts the BlackBerry smartphone operating system, and restarts the hardware components of the BlackBerry smartphone, including the wireless transceiver.

Note: a hard reset will not delete any settings or data on the BlackBerry smartphone.

To perform a hard reset, complete the following steps:

1. Turn the BlackBerry smartphone off.
2. Remove the battery.
3. Re-insert the battery.
4. Wait for the BlackBerry smartphone to turn on.

Note: If the issue returns after performing a hard reset, then contact technical support for further investigation.

Update the BlackBerry Device Software

You can download the latest version of Blackberry Device Software from www.blackberry.com/update. Follow the instructions on the screen to download the latest version currently available from your wireless service provider.

If the problem persists, follow your wireless service provider's procedures to service or return the BlackBerry smartphone.
