(see page 9).
® PEAK Level Indicator
In record mode, the indicator flashes in red corresponding to the
extremely short high level pulses which the VU meters cannot
follow. See “Record level adjustment", page 13.
@VU Meters
The meters show the input level in record moda and the recorded
level in playback mode. The left meter is for the left channel and
the right one for the right channel.
The feft meter also functions as a battery check meter.
@Recording Level Controls [REC LEVEL}
These controls adjust the recording level. The concentric knobs
can regulate the right- and left-channel level simultaneously or In-
dependently. The inner knob is for the right channel and the
outer for the left channel.
@ LIMITER Switch
This switch automatically attenuates the high intensity peaks, en-
countered in recording, to hold the recording level below distor-
tion point. With this switch at the ON position after setting the
recording level, the timiter circuitry operates only when a sudden
high input signal is introduced, thus preventing tape saturation.
Use this switch when recording programs containing high level
bursts which might cause distortion.
@ Metal Fitting (for shoulder strap)
@ MICROPHONE Input Jacks
Any low-lmpedance microphone equipped with a Phone plug may
be used. If your microphone is equipped with a miniplug, a plug
adaptor for converting to phone plug Is required.

@ Microphone Attenuator Switch [MIC ATT]
This switch is useful for recording a high input signa} on location
{rock music, ete), of recording with the microphone close to the
source, without overloading the recorder amplitier. Set this
switch to the “20 dB” position when the pointers of the VU
meters swing repeatedly over 0 VU with the REC LEVEL controls
set around the indication "3" or lower. The input signals will be
attenuated by 20 dB.
@ Normally this switch should be set to 0 dB.

CONNECTIONS
Notes on connection
@ When recording from the LINE IN jacks, remove any con-
nections from the MICROPHONE jacks.
@ When interconnecting electronic equipment with the TC-D5,
there are certain conditions that should be observed. tn general,
the output impedance of a signal source shoutd be much jower
than the input impedance of the device to be connected to the
signal source, The output level of a signal source should be equal
to or stightly higher than the rated sensitivity of the other device.
These specifications, both for Sony and other makes of equip-
ment may be found in the instruction manual of the particular
plece of equipment.
@ Turn off the recorder, amplifier, and other connected devices
before making connections.
© insert the cable connectors fulty into the jacks.
Loose connections may cause hum and noise.
@ The red plug of the connecting cord should be connected to
the right channel and the other plug to the left channel.

Recording level adjustment
High recording level Is recommended to reduce annoyance of
tape nolse, but overloaded and distorted tapes could result if the
level Is too high. Generally, recording level should be adjusted so
that the pointers of the meters deflect as close as possibie to 0
at the highest signal-level passage of the program you want to
record. The pointers may go over 0 for an Instant at sudden high
level bursts, but usually this Is not a problem. Such bursts can be
detected by the flashes of the PEAK level indicator. Try to keep
the overall level at a value causing minimum triggering or flashing
of the PEAK level indicator. This Indicator follows the transtent
peaks of occasional high level inputs that cannot be followed by
VU meters.

MAINTENANCE
Cleaning the heads
Keeping the tape heads in a clean condition is essential to the
proper operation of the recorder. Accumulations of dust and tape
oxides on the heads will result in sound drop-outs, a loss of high
frequencies and excessive tape wear. Generally, cleaning after
every 10 hours of operation will be sufficient. However, all sur-
faces over which the tape travels should be cleaned before
making high quality recordings
To clean the heads:
@ Open the Cassette Compartment Lid. Remove the cassette, if
present.
@ Depress the FWD button to move the heads out for easter
access,
@ Moisten the Head Cleaning Tip (supplied) or a soft cloth with
denatured alcohol, and gently wipe the heads, Capstan and Pinch
Rotler over which the tape travels
Erase Head
Capstan
Pinch Roller Record/Playback Hea
@To avoid catching the cotton between the Pinch Roller and
Capstan, insert the tip trom the side shown and depress the
PAUSE button when wiping the Capstan.
© Depress the STOP button to release the FWD button.
® Do not insert a cassette if the heads are protruding; first press
the STOP button
@ Do not insert a cassette before the alcohol has dried com-
pletely
Oemagnetizing the heade
Either prolonged use, or an accidental contact with a piece of
magnetized steet (screwdriver, scissors, etc.) will magnetize the
heads causing an increase in tape noise. The heads and metallic
parts of the tape path should be demagnetized after 20-30 hours
of operation using a commercially available head demagnetizer.
@ When demagnetizing, remove the batteries and disconnect the
ac power adaptor.
@ The Sony Head Demagnetizer HE-3 is recommended.
Cleaning the cabinet
Clean the cabinet with a soft cloth slightly moistened with water
or a mild detergent solution. Do not use solvents such as alcohol,
benzine, or thinner as they may mar the finish of the cabinet.
inside check
Consult your nearest Sony service facility to maintain optimum
performance.

removed, simply cover the siot with callophane or vinyl tape.
cellophane
tape
Remove the
broken tab.
To protect side A recording Do not stick any other mate-
al except on the circled
portions.
Note: Be careful not to cover the detector slots of the chromium
dioxide cassette.
Cassette care
@ Before Inserting a cassette, take up the slack of the tape to
prevent it from becoming entangled around the capstan.
@ Avoid touching the tape surface of a cassette, as any dirt or
dust may cause contamination of the heads.
@ Protect cassettes from dust by storing them in thelr cases.
Even minor dirt or dust could cause contamination of the heads
resulting in nolse and sound drop-outs.
@ Keep cassettes away from magnetic equipment such as
speakers, amplifier, etc., as erasure or distortion on your record-
ed tape could occur.
@ Do not expose a cassette to direct sunlight, extremely cold
temperature or moisture.
@ Avoid fast-winding Just before storing a cassette tape, as this
may cause stretching of the tape edge If it is left over a period of
time.
@ Do not stick thick paper or tape to the cassette, as this may
affect proper cassette alignment and disturb good tape contact
with the head.
