IMPORTANT SAFETY INSTRUCTIONS
1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this apparatus near water.
6) Clean only with dry cloth.
7) Do not block any ventilation openings. Install in accordance with
the manufacturer’s instructions.
8) Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers) that
produce heat.
9) Do not defeat the safety purpose of the polarized or groundingtype plug. A polarized plug has two blades with one wider than
the other. A grounding type plug has two blades and a third
grounding prong. The wide blade or the third prong are provided
for your safety. If the provided plug does not fit into your outlet,

10) Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
11) Only use attachments/accessories specified by the manufacturer.
12)Use only with the cart, stand, tripod,
bracket, or table specified by the
manufacturer, or sold with the apparatus.
When a cart is used, use caution when
moving the cart/apparatus combination to
avoid injury from tip-over.
13) Unplug this apparatus during lightning storms or when unused
for long periods of time.
14) Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way,
such as power-supply cord or plug is damaged, liquid has been
spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate normally,
or has been dropped.
<
Do not expose this apparatus to drips or splashes.
< Do not place any objects filled with liquids, such as vases, on the
apparatus.

The apparatus should be located close enough to the AC outlet
so that you can easily grasp the power cord plug at any time.
<
An apparatus with Class !construction shall be connected to an
AC outlet with a protective grounding connection.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK). NO USERSERVICEABLE PARTS INSIDE. REFER SERVICING TO
QUALIFIED SERVICE PERSONNEL.
The lightning flash with arrowhead symbol, within an
equilateral triangle, 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.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.
WARNING: TO PREVENT FIRE OR SHOCK
HAZARD, DO NOT EXPOSE THIS APPLIANCE
TO RAIN OR MOISTURE.
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 equipment and/or 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.
CAUTION
Changes or modifications to this equipments not expressly
approved by TEAC CORPORATION for compliance will void the

placing it in direct sunlight or close to a source of heat. Also
avoid locations subject to vibrations and excessive dust, heat,
cold or moisture.
<
Do not place the unit on the amplifier/receiver.
<
Do not open the cabinet as this might result in damage to the
circuitry or electrical shock. If a foreign object should get into
the unit, contact your dealer or service company.
<
When removing the power plug from the wall outlet, always
pull directly on the plug, never yank the cord.
< Do not attempt to clean the unit with chemical solvents as
this might damage the finish. Use a clean, dry or slightly
damp cloth.

Connecting Antennas
FM Indoor Antenna
In an area with strong FM signals, the T-type FM antenna
provided with this unit is sufficient.
Extend the antenna into a “T” shape and connect the two
wires at the base of the “T” to the provided matching
transformer, as shown.
After completing connection, plug the transformer into the
“FM 75Ω” socket. Extend the top of the “T” and tune the
tuner to your favorite station (see page 8). Adjust the antenna
in a suitable location like a window frame or wall until the
reception is best and then affix the antenna in that position
using thumb tacks, push pins or any other suitable means.
CAUTION:
<
Switch off the power to all equipment before making
connections.
<
Read the instructions of each component you intend to use
with this unit.
<
Be sure to insert each plug securely. To prevent hum and
noise, avoid bundling the signal interconnection cables
together with the AC power cord or speaker cables.
AM Indoor Loop Antenna
The high-performance AM loop antenna provided with this
unit is sufficient for good reception in most areas.
Snap the supplied loop antenna into the hinge on the rear of
the unit, and connect the wires running out the loop antenna
to the AM terminals, as shown.
When you actually try listening AM programs later, you may
want to turn the loop antenna on the hinge for the best
possible reception.
AM Outdoor Antenna
If the AM loop antenna provided does not deliver sufficient
reception (often due to being too far from the transmitter or
in a concrete building, etc.), it may be necessary to use an
outdoor AM antenna.
Use either a high quality commercial AM antenna or, if not
available, an insulated wire more than 5 m (15 feet) long,
strip one end, and connect this to the terminal as shown.
The antenna wire should be strung outdoors or indoors near
a window. For better reception, connect the GND terminal to
a reliable ground.
Note:
Even when using an outdoor AM antenna, do not disconnect
the AM loop antenna.
FM Outdoor Antenna
In an area where FM signals are weak, it will be necessary to
use an 75-ohm unbalanced-type outdoor FM antenna.
Generally, a 3-element antenna will be sufficient; if you live in
an area where the FM signals are particularly weak, it may be
necessary to use one with 5 or more elements.
<
If you are using a 300-ohm antenna, connect it to the tuner
via the supplied matching transformer. (No need for it in
connecting a 75-ohm antenna.)
<
Disconnect the FM indoor antenna when using an outdoor
antenna.

Voltage Conversion
Be sure to remove the power cord from the AC outlet before
repositioning the voltage converter switch.
1. Locate the voltage selector on the rear panel.
2.Using a flat-bladed screwdriver, set to the appropriate
230V or 120V position according to your area.
IN NORTH AMERICA USE ONLY ON 120 V SUPPLY.
RESET switch
In the following cases, function buttons may not work
properly.
• When the system is damaged by electrical shock.
• When the power is irregular or has electrical noises.
In these cases, press the RESET switch once or twice with a
pencil or a ball-point pen lightly.
All the settings kept in memory (such as preset stations) will
be erased.
