Installing the Wave Expansion Board

Cautions When Installing a Wave Expansion Board

901

•To avoid the risk of damage to internal components that can be caused by static electricity, please carefully observe the following

whenever you handle the board.

1

•Before you touch the board, always first grasp a metal object (such as a water pipe), so you are sure that any static electricity you might have been carrying has been discharged.

2

•When handling the board, grasp it only by its edges. Avoid touching any of the electronic components or connectors.

5

•Save the bag in which the board was originally shipped, and put the board back into it whenever you need to store or transport it.

•Use a Philips screwdriver that is suitable for the size of the screw (a number 2 screwdriver). If an unsuitable screwdriver is used, the head of the screw may be stripped.

•To remove a screw, rotate the screwdriver counter-clockwise. To tighten the screws, rotate the screwdriver clockwise.

•Be careful that the screws you remove do not drop into the interior of the MC-909.

•Be careful not to cut your hand on the edge of the cover or the

opening edge while removing the cover.

911

• Do not touch any of the printed circuit pathways or connection terminals.

912

•Never use excessive force when installing a circuit board. If it doesn’t fit properly on the first attempt, remove the board and try

again.

913

• When circuit board installation is complete, double-check your work.

914

•Always turn the unit off and unplug the power cord before attempting installation of the circuit board (SRX series; Quick

Start p. 2).

915

• Install only the specified circuit board (SRX series). Remove only the specified screws (p. 142).

928

•When turning the unit upside-down, get a bunch of newspapers or magazines, and place them under the four corners or at both ends to prevent damage to the buttons and controls. Also, you should try to orient the unit so no buttons or controls get

damaged.

929

•When turning the unit upside-down, handle with care to avoid dropping it, or allowing it to fall or tip over.

•Do not leave the bottom cover removed. After installation of the Wave Expansion Board is complete, be sure to replace the cover.
