Page 12: Disassembly/Assembly
6. Disassembly and Assembly 6-1. Disassembly and Attachment of Upper and Lower Case 1) Remove the main batteries (SUM3 alkaline batteries x 2) and lithium battery (CR2032 x 1). (Refer to the "Instruction Manual" for the removal procedure.) 2) Remove the five flat screws (2 x 5 Ni) (A in diagram at right). - Page 13 6-2. Attachment and Removal of P690-SUB Board 1) Remove the two flat screws (2 x 3.5) and raise up the P690-SUB board. 2) Disconnect the FFC joiner of the P690-SUB board from the connector. First, slide the connector opening with a tweezers or similar tool and then pull out the joiner after loosening the opening.
- Page 14 3) Attachment is performed by following the reverse procedure of removal. Insert the FFC joiner into the space below the laser module while making sure it does become pinched between the upper case and lower case. * Do not touch the screw adjustment above the laser module! 6-4.
- Page 15 4) Remove the two flat screws (2 x 3.5). 5) Stand up the P690-MAIN board while disconnecting the locking hooks (see diagram at right). However, perform this procedure carefully since an auxiliary SUB2 board is connected to the old MAIN board, and that auxiliary SUB2 board is difficult to remove as a result of being adhered to the inner case with...
- Page 16 6-6. Removal and Attachment of Upper Case Key Unit 1) Since the rubber keys and key film are adhered with double-sided adhesive tape in the order shown below, remove each component by carefully prying a small minus precision screwdriver or similar tool between the gaps while being careful not to damage the upper case.
