Precautions
On safety
¢ Do not disassemble the cabinet as this may result in an
electric shock. Refer servicing to qualified personnel only.
¢ Should any solid object or liquid fall into the cabinet, unplug
the AC power cord before operating the unit any further.
On power sources
¢ Before operating the unit, check that its operating voltage is
identical with your local power supply. The operating
voltage is indicated on the nameplate at the rear of the unit.
¢ 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.
¢ If you are not going to use the unit for a long time, be sure to
disconnect the AC power cord (mains lead) from the wall
outlet. To disconnect the cord, grasp the plug itself; never
pull the cord.
¢ AC power cord must be changed only at the qualified
service shop.
On operation
If the unit is brought directly from a cold place to a warm place,
or is placed in a very damp room, moisture may condense
inside the unit, "CAUTION"
may appear in the display, and
the unit may not operate. If this happens, remove the cassette
and leave the unit turned on for about an hour until the
moisture evaporates.
On placement
¢ Place the unit in a location with adequate ventilation to
prevent heat build-up.
¢ Do not place the unit:
— ona
soft surface such as a rug that might block the
ventilation holes on the bottom.
— near heat sources.
— in direct sunlight.
— inan inclined position.
— ina place subject to excessive dust or mechanical shock.
On the tapes
¢ After using a tape, put it into its case and keep it where it
will not be subject to sunlight, high temperature, moisture or
dust.
¢ Do not use thin-tape cassettes (with a playing time of over
120 minutes) since this may cause the unit to display
inaccurate time information, or result in tape damage caused
by abnormal operation.
¢ The DAT cassette shell is designed to keep out dust. Do not
open the case to expose the tape.
The hole at the back of the cassette is the detector slot. Do not
cover this slot.
For the customers in the U.S.A.
For detailed safety precautions, see the leaflet "IMPORTANT
SAFEGUARDS."
If you have any questions or problems concerning your
unit, please consult your nearest Sony dealer.

Cleaning
Cleaning the cabinet, panel and controls
Use a soft cloth slightly moistened with a mild detergent
solution. Do not use any type of abrasive pad, scouring
powder or solvent such as alcohol or benzine.
Cleaning the head and tape path
¢ Prolonged operation will cause contamination of the head.
To obtain the best possible recording and playback sound,
we recommend that you use the Sony DT-10CL cleaning
cassette (not supplied) to clean the head after every ten
hours or so of operation.
¢ Clean the head with the cleaning cassette when the deck has
not been used for a long period of time.
Contamination of the head may cause sound drop-out
during playback.
Using the cleaning cassette
1 Insert the cleaning cassette as you would a normal DAT
cassette.
2 Press >. After 10 seconds, press Ml.
Do not press the REC @ or >> button for cleaning.
3 Remove the cleaning cassette without rewinding it. You
should rewind the cleaning cassette only when it has
reached the end.
Notes on cleaning
¢ After 10 hours of operation, "CLEANING" appears in the
display for about ten seconds when you turn on the deck. It
is recommended that you clean the head and tape path
periodically, using this message as a guide.
¢ Due to the shortness of the cleaning cassette, the counter will
not show the actual running time and remaining time of the
cassette.
