2.4.2 Removing RF and Logic Boards From Chassis
Remove the Rf and Logic Boards as follows:
1 Separate the front cover and chassis as described in the preceding section. The RF and
Logic Boards are located inside the metal chassis as shown below.
2 Remove the shields over the RF and Logic Boards. These shields insert in slots on one
side of the chassis and then clip to the other side of the chassis. These shields also hold
the boards in place.
3 Unplug the antenna cable from the RF Board using pliers or a similar tool at the
location shown below. Unlock the Logic Board flex circuit by sliding the tab on the
connector outward. The RF and Logic Boards can now be removed.
When handling these boards, minimize bending of the flex circuit to prevent it from being
damaged.
