Mouse Balls

This is an actual field alert to IBM Field Engineers that went to all

IBM branch offices. The person who wrote it was very serious. The rest

of us find it rather funny...

RE: Mouse balls available as FRU (Field replacement units)

Mouse balls are now available as FRU. Therefore, if a mouse fails to

operate or should it perform erratically, it may need a ball

replacement. Because of the delicate nature of this procedure,

replacement of mouse balls should only be attempted by properly trained

personnel.

Before proceeding, determine the type of mouse balls by examining the

underside of the mouse. Domestic balls will be larger and harder than

foreign balls. Ball removal procedures differ depending on the

manufacturer of the mouse. Foreign balls can be replaced using the

pop-off method. Domestic balls are replaced using the twist-off

method. Mouse balls are not usually static sensitive. However,

excessive handling can result in sudden discharge. Upon completion of

ball replacement, the mouse may be used immediately.

It is recommended that each replacer have a pair of spare balls for

maintaining optimum customer satisfaction and that any customer missing

his balls should suspect local personnel of removing these necessary

items.

To reorder - specify one of the following:

*Domestic Balls

*Foreign Balls
