Removal and Attachment of P690-MAIN Board
1) Raise out the two main battery springs on the side
on which the lead is connected.
2) Remove the two flat screws (2 x 5 Ni) and
separate the inner case from the upper case for
both the MAIN board and LCD. However,
remove the LCD carefully since it is difficult
to remove as a result of the periphery being
adhered to the upper case with double-sided
adhesive tape.
3) Remove the key film connected to the P690-
MAIN board from the connector. The key
film is removed by opening the connector
opening (dark brown portion) upward.
