MV-8800 Using the MV8-OP1
Installing the MV8-OP1
●
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.
❍
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.
❍
When handling the board, grasp it only by its edges. Avoid touching any of the electronic components.
❍
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.
●
Do not touch any of the printed circuit pathways.
●
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.
●
When circuit board installation is complete, double-check your work.
●
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.
●
When turning the unit upside-down, handle with care to avoid dropping it, or allowing it to fall or tip over.
●
Use a Philips screwdriver of the appropriate size to avoid damaging the screw heads (a number of 2
screwdriver). If an unsuitable screwdriver is used, the head of the screw may be stripped.
●
Turn the screwdriver counter-clockwise to loosen the screws-turn it clockwise to tighten them.
●
Be careful not to let the screws drop inside the MV-8800’s body.
●
Do not leave the option slot cover removed. After installation of the MV8-OP1 is complete, be sure to replace the
cover.
●
Be careful not to cut your hand on the edge of the cover or the opening edge while removing the cover.
