(compressor/expander)

system

enables

is

designed

for

use

in

an

ambient

temperature

range

of

0°C

to

50°C

(32°F

to

122°F).

Do

not

place

the

unit

on

or

near

a

heat

source

such

as

lighting

equipment

or

a

power

amplifier,

or

in

sunlight

or

excessive

moisture.

In

such

places,

the

external

finish

or

may

be

damaged.

If

the

unit

is

used

in

a

very

humid

subject

to

an

active

gas,

clean

its

surface

as

well

as

the

with

a

dry,

soft

cloth

soon

after

the

use.

Lengthy

use

of

the

unit

in

such

places

or

not

cleaning

it

after

its

use

in

such

places

may

shorten

its

When

cleaning

the

unit,

never

use

organic

solvents

such

as

thinners

or

benzine,

which

will

damage

the

finish

of

the
