PRECAUTIONS

FOR

INSTALLATION

DRA-25/25L

uses

a

newly

developed

heat

emitting

unit

by

employing

heat

pipes.

Since

the

heat

pipes

contain

a

coolant,

the

DRA-25/25L

must

be

set

level

or

the

desired

heat

emitting

effect

cannot

be

achieved.

Always

instal!

this

unit

horizontally.

ADVICE

FOR

USE

e

Do

not

place

the

set

in

direct

sunlight,

in

hot

areas

such

as

near

heating

equipment,

with

high

humidity

or

dust

levels.

This

may

cause

damage

to

the

unit.

Check

that

all

parts

are

connected

correctly

before

turning

on

the

power

source.

When

user

is

absent

for

jong

periods,

be

sure

to

remove

plug

from

It

is

not

recommended

to

place

players,

decks

and

other

objects

on

the

DRA-25

or

DRA-25L

so

that

the

vents

are

blocked,

This

will

cause

internal

temperature

rise

and

equipment

failure.

Do

not

use

the

DRA-25

or

ANTENNA

The

accessory

T-type

indoor

antenna

(300

ohms)

can

be

used

inside

wooden

houses

for

local

FM

stations

and

strong

signals.

Orient

the

T-shaped

part

for

optimum

reception

and

mount

the

antenna

on

the

wall

or

ceiling.

(FM

indoor

antennas

may

not

consistently

ensure

stable

reception,

due

to

environment

changes.

In

such

cases

use

an

FM

indoor

antenna

temporarily

until

an

outdoor

antenna

is

installed.)

75

ohms

coaxial

cable

(3C-2V,

5C-2V)

is

preferable

to

obtain

better

performance

of

the

tuner.

(To

antenna,

connect

to

the

Use

this

Orient

the

horizontally

to

obtain

optimum

reception.

Where

broadcast

stations

are

distant

and

only

weak

are

received,

or

where

are

blocked

by

obstacles,

instal!

an

GROUNDING

If

there

is

reception

noise,

use

of

grounding

wire

is

recommended.

Connect

a

thick

insulated

wire

to

the

“GND”

terminal,

and

attach

the

unconnected

bare

end

to

a

metal

water

pipe,

grounding

rod,

or

grounded

Never

connect

the
