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 operation and maintenance
(servicing) instructions in the literature accompanying
the appliance.

Caution: To prevent electric shock do not use this (polarized) plug with

an extension cord, receptacle or other outlet unless the blades
can be fully inserted to prevent blade exposure.

Attentions: Pour prévenir les chocs électriques ne pas utiliser cette

fiche polarisée avec un prolongateur, une prise de courant
on une autre sortie de courant, sauf si les lames peuvent

- DIGITAL TUNER

Ability to store up to thirty broadcasting frequencies in the system’s memory, in a simple and easy to use manner.

- 1CD/MP3

The product has a built-in CDP than can play back the CD stored in a MP3 file format to enable convenient
use.(Support playback of CD in CD/MP3 format.)

Operation

Operation

1. Before inserting the power plug to a socket, turn all switches off, put the tone control to the middle, and the

volume to the lowest position.

2. Check if a speaker and input jack are connected correctly.

3. Check the power source and insert a power cord to a socket.

4. Pressing a power switch starts the unit.

5. Checking the volume from an output level indicator, adjust the volume with individual volume and master

volume control, and the tone with a tone control as you want.

6. For the operation of chime, CD and deck, see the relevant detail description in the document.

Make certain that speakers and input sources are properly connected before switching the unit on.
Keep volume levels turned down before switching on.
NOTE: The system’s operation is delayed by approximately three seconds after pressing the power switch. This

Application of The Antenna

Application of The Antenna

- FM RECEIVING ANTENNA

The electric wave of FM broadcasting is weakening in hills and valleys, around buildings and in iron­reinforced buildings.

- INSTALLATION OF ANTENNA EXCLUSIVELY FOR FM

Listening to the broadcasting, fix the antenna after deciding the location and the direction so that the reception
may be optimized.

- INSTALLATION OF ANTENNA USING THE COAXIAL CABLE

Noisy reception may occur in built-up areas and factory sites as well as around power cables. This may be the case
even when an antenna is used exclusively for FM. In these regions, install the antenna using 75Ω coaxial cable.

- INDOOR ANTENNA

In the regions where FM broadcasting is heard comparatively well due to the near distance to the station or
wooden structure, you can receive broadcasting of good quality by using T-type antenna.

- AM LEAD ANTENNA

Fix one end of a six to eight metre length of vinyl-coated single cable to the AM terminal and the other end to
a high place like a wall.

- AM OUTDOOR ANTENNA

Install the vinyl-coated cable to an outdoor place if the AM reception is not good enough.

Installation of The Speaker

Before you connect the speaker, remove the power cord from the power outlet and switch the ACR-120M power
switch off. When connecting the speaker wires to the SPEAKER OUTPUT terminals, use the output terminals that
are suitable for the speaker (see below).
Extreme care must be exercised when connecting to these terminals as potentially hazardous voltages may be present.
