Follow these steps to install crys- tals.

1.Remove the battery pack and the antenna.

2.Use a Phillips screwdriver to remove two of the screws on the battery guide plate as shown. Then loosen the other two screws on the battery guide plate about 4 full turns. (This makes it easier to reinstall the back cover later).
