Replacing the back cover
The phone's antennas are placed underneath the back cover. To
get the best signal for calls, data connection, or GPS navigation, be
sure to secure the back cover tightly to the phone.
1. Align the back cover onto the top panel of HTC Rezound with
Beats Audio.
2. Press the sides of the back cover down to lock it into place. You'll
hear clicks when the small tabs underneath the back cover are
locked in place.
