Wearing the headset
Do not bend the mounting clip away from the body or apply too much •
pressure on it as this could cause permanent damage to the clip or
headset.
If you have poor call quality issues, make sure that the earbud is
•
properly placed over the ear hole or the microphone is not blocked.
The call quality may vary depending on how you grip your bluetooth
•
headset. To minimize interference, we recommend you hold the middle
bottom part of the headset while talking on the phone.
