5 Appendix
5.1 TROUBLESHOOTING
If you cannot get the headset to work, try the following:
- Turn off the devices and turn them on again.
- Ensure the headset is charged.
- Ensure devices are within the 10-meter (33 feet) range.
- Ensure no obstructions such as thick concrete walls are between con-
necting devices.
Try the following to troubleshoot an audio problem when connected to a computer.

No. The pairing information will be stored in both devices even if one or both of them have been
turned off.
5. IS IT NECESSARY TO RECONNECT THE TWO DEVICES WHEN THERE IS AN
INTERRUPTION ON THE LINK BETWEEN MY PHONE AND HEADSET?
It varies according by phone. Some phones can be reconnected automatically if both devices are
within the effective distance; some must be reconnected.
