For best reception of FM broadcasts, select an FM antenna with
the best characteristics for the area in which the unit is to be
used.

5. To avoid danger, away from electric power lines.
Danger close to power lines
This unit includes an AM loop antenna. No outdoor antenna is
necessary unless the broadcast signals in your area are
especially weak. (Connect the loop antenna even if an outdoor
antenna is used; if it is not connected, AM reception will not be
possible.)
E How to use the AM loop antenna
Pay attention to the following points when attaching the
antenna.
1)Do not attach it horizontally (to do so would impair
reception).
2) Do not attach it close to metal surfaces (to do so would
result in noise).
3) Do not attach it Close to power cords, speaker wires, etc.
(to do so would result in noise).
4) Do not attach it close to a tape deck (when the tape deck is
being used, chirping or beeping sounds may be received).
1. Connect the AM loop antenna to the AM antenna terminals
located on the rear panel of the unit. (Refer to page 6)
2. Find the height and direction of the antenna where reception
is best and then fix it vertically to the wall, rack, etc.
1) When attaching the antenna to a wall, column or rack.

B Connection of an outdoor antenna
If an outside AM antennais installed (in mountainous regions or
between reinforced-concrete buildings), install it in a location
away from utility poles, high-voltage power lines, high buildings
and busy roads.

The protection circuitry may have operated if either of the
following conditions is noticed:
e No sound is heard when the power is turned on.
* Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for
example, the positive and negative speaker connection wires
are ‘shorted”, or if speaker systems with an impedance less than
the indicated rated impedance of this unit are used.
If this occurs, follow the procedure outlined below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once again.

Before requesting service for this unit, check the chart below for
a possible cause of the problem you are experiencing. Some
simple checks or a minor adjustment on your part may eliminate
the problem and restore proper operation.
If you are in doubt about some of the check points, or if the
remedies indicated in the chart do not solve the problem, refer to
the directory of Authorized Servicenters (enclosed with this unit)
to locate a convenient servicenter, or consult your Technics
dealer for instructions.
Problem
Probable cause(s) _
During disc play
A loud and unusual
sound (“howling”) is
heard when the volume
level is increased.
Suggested remedy
| The location of the turntable and speaker
systems is unstable.
elf the equipment is unstable because it is located
upon a soft surface, such as a carpet, place a solid
material (such as concrete blocks, bricks, a hard
board, etc.) beneath the speaker systems.
* Close the cover of the turntable.
e Try moving the turntable farther away from the
speaker systems.
* Try placing a cushioning material (such as felt or
commercially available audio insulators) beneath
the turntable.
Unusual scratching

"|" An unusual hissing
noise is heard when
listening to the broad-
cast in stereo, but not
heard when listening
monaurally.
A slight noise may be heard because the
method used for modulation of FM stereo
broadcasts is different than that used for
monaural broadcasts.
Noise is excessive in
both stereo and
monaural broadcasts.
Poor location and/or direction of the antenna.
Transmitting station is too far away.
* Try reducing the treble sound by the treble tone
control (à.

monaural sound.)
