Appendix

B.

Cleaning

the

mouse

This

appendix

provides

instructions

on

how

to

clean

your

mouse.

The

procedure

will

be

different

depending

on

which

type

of

mouse

you

have.

Cleaning

an

optical

mouse

If

you

experience

some

problems

with

your

optical

mouse,

check

the

following:

1.

Turn

the

mouse

over

and

look

carefully

at

the

lens

area.

a.

If

there

is

a

smudge

on

the

lens,

gently

clean

the

area

with

a

plain

cotton

swab

or

plain

q-tip.

b.

If

there

is

some

debris

in

the

lens,

gently

blow

the

debris

away

from

the

area.

2.

Check

the

surface

you

are

using

the

mouse

on.

If

you

have

a

very

intricate

picture

or

pattern

beneath

the

mouse

it

is

difficult

for

the

digital

signal

processor

(DSP)

to

determine

changes

in

the

mouse

position.

need
