BLADE EXPOSURE.
This apparatus complies with the Class B limits for radio
noise emissions set out in Radio Interference Regulations.
NOTICE FOR CUSTOMERS IN THE UNITED KINGDOM
A moulded plug complying with BS 1363 is fitted to this
equipment for your safety and convenience.
Should the fuse in the plug supplied need to be replaced, a
5 AMP fuse approved by ASTA or BSI to BS 1362, (i.e.
marked with © or Y mark) must be used.
If the plug supplied with this equipment has a detachable
fuse cover, be sure to attach the fuse cover after you
change the fuse. Never use the plug without the fuse
cover. If you should lose the fuse cover, please contact
your nearest Sony service station.
IMPORTANT
If the plug supplied is not suitable for the socket outlets in

On safety
*Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified personnel
before operating it any further.
*Unplug the unit from the wall outlet if it will not be used
for a long time. To disconnect the cord, pull it out by
grasping the plug. Never pull the cord itself.
The unit is not disconnected from the AC power source
(mains) as long as it is connected to the wall outlet, even if
the unit itself has been turned off.
On operation
¢ When the unit is not used, turn the power off to conserve
energy and to extend the useful life of your unit.
* Because of a safety mechanism, the function buttons will
not operate if the cassette holder is not completely closed, if
there is no cassette in the cassette holder, or if a cassette has
been incorrectly inserted into the cassette holder.
On head cleaning
The head and tape path should be cleaned after every ten
hours of operation. Dirty heads and a dirty tape path may
cause:
— loss of high-frequency response
— loss of sound volume
— sound drop-out
If you have any questions or problems concerning your unit,
please contact your nearest Sony dealer.
For the customers in the U. S. A.
For detailed safety precautions, see the leaflet “IMPORTANT
SAFEGUARDS”.

Checking the Supplied Accessories
Make sure that the following supplied accessories are
included with your unit.
* Audio connecting cords (2)
Koy Cormel aM laryeclitcvete) a)
Place the unit with the front panel facing you in a location
with adequate air circulation to prevent overheating of the
unit.
*Do not place the unit:
— near heat sources such as radiators or air ducts.
— in places subject to direct sunlight, excessive dust,
mechanical vibration or shock.
— in an inclined position.
— on a rug or other soft surfaces that would block the
ventilation holes on the bottom of the unit.
Do not throw away the carton and the packing material
They will come in handy when transporting the unit or
shipping it for servicing.
Checking the Operating Voltage
Operate the unit only on 120 V AC, 60 Hz (U.S.A. and
Canada model), 240 V AC, 50 Hz (U.K. model) or 240 V
AC, 50/60 Hz (Australia model).
*Before connecting the unit to an AC outlet, be sure that the
operating voltage of your unit is identical with that of your
local power supply.

Hooking Up the System

noise in low-level, high-frequency signals by boosting the
signals during recording and lowering them during
playback.
Note
The Dolby HX PRO system works only during recording, not
during playback (TC-WR545 only).

following cases:
elf you press the PP (or 44 ) button immediately before
the selection.
elf there is noise in the space before the selection.
elf the space before the selection is less than four seconds
long.
The Multi-AMS will treat the following as blanks:
A long pause in the music

add new selections to the existing program.
To check the contents of a program
Press the CHECK button anytime while RMS mode is active.
Pressing the button shows each programmed selection in the
order they were programmed, starting with the first.
Pressing the button after the last selection causes “End” to
appear momentarily in the display window.
To alternate between the RMS and peak level
meter displays
Press the DISPLAY button. The peak level meter display
does not change if there is no RMS program.

on deck A, and the << , PB , H buttons on deck B are
operative.
¢The Multi-AMS function may skip a selection if:
— there is noise in the space before the selection.
— the space before the selection is less than four seconds
long.
elf there is a blank space of more than 13 seconds long, the
unit will fast-forward the tape until the end of the blank
space.
elf the unit encounters a program number that exceeds the
number of selections on the tape, the unit fast-forwards the
tape to the end, erases that and all excessive program
numbers from the program, then continues RMS playback
if program numbers for existing selections remain, or stops
RMS playback if no program numbers remain.

Tips on recording level adjustment
Setting the recording level too low will produce a hissing
sound, while setting it too high will produce distortion.
Generally, the proper recording level for high and low
frequencies is lower than that for middle frequencies. When
recording program sources with many high and low
frequencies, set the level to a relatively low position, then
make adjustments according to recording results.
Recording FM Broadcasts with the Dolby NR
System (TC-WR545 Only)
If your tuner does not have an MPX (multiplex) filter, or, if
equipped, the filter is not working effectively, set the MPX
FILTER switch to ON when recording FM broadcasts with
the Dolby NR system.
The multiplex filter eliminates remnants of the 19 kHz stereo
carrier and 38 kHz subcarrier signals which may impair the
operation of the Dolby NR system. Be sure to turn on the
MPX FILTER switch when using the Dolby NR system.
What Is the Dolby HX PRO System?
(TC-WR545 Only)
The Dolby HX PRO system provides precise bias control
during recording to reduce distortion and improve linearity
in the high-frequency range. The result is recorded sound
that is highly faithful to the original. Since the HX PRO
system operates only during recording, the same high-
quality sound is produced even during playback on other
tape decks, The HX PRO system is independent from the
Dolby NR system and is unaffected by the Dolby NR setting.

Cassette Care
¢ Avoid touching the tape surface of a cassette to prevent
contamination of the heads by dirt, dust, or oil on the skin.
Keep cassettes away from equipment with magnets, such
as speakers and amplifiers, as erasure or distortion of the
recorded tape could occur.
¢Do not expose cassettes to direct sunlight, extremely cold
temperatures, or moisture.
Note on cassettes longer than 90 minutes
We do not recommend the use of cassettes longer than 90
minutes except for long continuous playback.

Calibration (TC-WR545 Only) ~
Though the Automatic Tape Selection (ATS) system in your unit automatically sets the
equalization characteristics, bias current and recording level to suit the magnetic properties of
each tape type, doing the automatic calibration procedure below for the bias current and
recording level may allow you to get even better recording results, especially in conjunction
with the Dolby NR system.

The CAL indicator lights up when existing calibration data

vary in their characteristics, we recommend that you repeat
the automatic calibration procedure each time you insert a
new cassette.
To recalibrate:
1 Insert the cassette.
The CAL indicator lights up.
2 Press AUTO CAL.
The CAL indicator turns off and the unit recalls the
existing calibration data for that tape type.
3 Continue from step 1 of the automatic calibration
procedure.

Notes
Since the unit records a test tone on the tape during
automatic calibration, recorded material on the tape is
erased where the test tone is recorded.
¢We recommend the use of relatively new tape and clean
heads to obtain the best calibration results. Excessively
worn tape or dirty heads may result in incorrect calibration
values.
¢ All calibration data are erased when you turn off the unit.
¢The automatic calibration function works only when both
decks are stopped.
Playback on deck A is disabled during automatic
calibration on deck B.
elt is unnecessary to select the Dolby NR system when
performing automatic calibration since the Dolby NR
setting does not affect the calibration results.

test tone.
— Damaged tape or dirty heads, Change the cassette or
