A DualDisc is a two sided disc product which mates 

DVD recorded material on one side with digital 

audio material on the other side. However, since the 

audio material side does not conform to the Compact 

Disc (CD) standard, playback on this product is not 

guaranteed.

This product is designed to playback discs that 

conform to the Compact Disc (CD) standard. 

Recently, various music discs encoded with copyright 

protection technologies are marketed by some 

record companies. Please be aware that among those 

discs, there are some that do not conform to the CD 

standard and may not be playable by this product.

The use of optical instruments with this product will 

increase eye hazard.

Use of controls or adjustments or performance of 

procedures other than those specified herein may 

result in hazardous radiation exposure.

To reduce the risk of fire, do not place any heating or 

cooking apparatus beneath this unit.

This symbol is intended to alert the user 

to the presence of uninsulated “dangerous 

voltage” within the product’s enclosure that 

may be of sufficient magnitude to constitute 

a risk of electric shock to persons.

This symbol is intended to alert the user to 

the presence of important operating and 

maintenance (servicing) instructions in the 

literature accompanying the appliance.

The graphical symbols are at the top of the enclosure.

Class II equipment symbol 

This symbol indicates that the unit has a 

double insulation system.

This equipment has been tested and found to 

comply with the limits for a Class B digital device, 

pursuant to Part 15 of the FCC Rules. These limits 

are designed to provide reasonable protection against 

harmful interference in a residential installation. 

This equipment generates, uses and can radiate radio 

frequency energy and, if not installed and used in 

accordance with the instructions, may cause harmful 

interference to radio communications. However, there 

is no guarantee that interference will not occur in a 

particular installation. If this equipment does cause 

harmful interference to radio or television reception, 

which can be determined by turning the equipment 

off and on, the user is encouraged to try to correct the 

interference by one or more of the following measures:

— 

Reorient or relocate the receiving antenna.

— 

Increase the separation between the equipment 

and receiver.

— 

Connect the equipment into an outlet on a 

circuit different from that to which the receiver 

is connected.

— 

Consult the dealer or an experienced radio/TV 

technician for help.

 Danger of explosion if battery is incorrectly 

replaced. Replace only with the same or equivalent

 Due to its heavy weight, the unit should be installed 

with great care.

 Installation of the unit requires two persons.

 Use tools carefully while installing of the unit.

 Be sure that the cabinet that is used is sturdy enough 

to support the weight of the unit.

 To reduce the risk of fire, do not place any heating or 

cooking appliance beneath this unit.

 Install the unit so that its AC power cord can be 

connected directly to a wall outlet. Do not use a 

converter or extension cord.

 Be sure that the AC power cord has no slack during 

use of the unit, since the cord acts as an FM wire 

antenna. If the AC power cord has some slack, wind 

it around the cord hook so as to eliminate the slack.

 The unit has a built-in ferrite bar antenna for AM 

radio reception. Confirm that AM reception is 

acceptable before finally attaching the unit.

 Install the unit as far as possible from sources of 

noise (for example, a refrigerator, microwave oven or 

fluorescent lamp).

 This unit is not waterproof. Install it where it will 

not be exposed to splashing by water, as this may 

damage the unit.

 To reduce the risk of fire or electric shock, do not 

touch the AC power cord with wet hands.

 Never place objects between the top of the unit and 

the bottom of the cabinet. This could cause the unit 

to fall.

 Make sure the unit’s four screws are fastened tightly.

 After installing the unit, do not pull down on it or 

hang something heavy on it.

   Decide on the installation location and 

orientation of the unit based on the best 

reception that is possible (see “Improving 

the reception”).

   Mark the position of the 4 holes by using 

the supplied template. Use a drill to make 

the holes (size 6.5 mm diam., 

9

/

32

 inch). (See 

Fig. -)

   When the cabinet door overhangs the shelf 

and obstructs the unit, you can adjust the 

unit/shelf height. 

First set the L mark to the dot which 

becomes the lowest position, then you 

can adjust the height in 4 steps (HL) 

by turning the spacer counterclockwise 

(See Fig. -). The unit can be installed 

without the spacer.

   Install the unit with the supplied mounting 

screws. (See Fig. -)

If you lose the supplied screws, please purchase #10 or 

M5 screws.
