SAFETY CHECK-OUT
After correcting the original service problem, perform the
following safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, "metallized" knobs, screws,
and ali other exposed metal parts for AC leakage. Check leakage as
described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part having
a return to chassis, must not exceed 0.5mA (500 microampers).
Leakage current can be measured by any one of three methods.
1. Acommercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type
recommended by the equipment manufacturer. Discard
used batteries according to manufacturer's instructions.
ADVERSEL !
Lithiumbatteri ~ Eksplosionsfare ved fejlagtig handtering.
Udskiftning ma kun ske med batteri

ADVARSEL
Lithiumbatteri — Eksplosjonsfare.
Ved utskifting benyttes kun batteri som
anbefalt av apparatfabrikanten.

Vaihda paristo ainoastaan laitevalmistajan suosittelemaan
tyyppiin. Havita kaytetty paristo valmistajan ohjeiden
mukaisesti.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The "limit" indica-
tion is 0.75V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2V AC range are
suitable. (See Fig.A)

Clock Setting
This unit uses a built-in clock to keep track of the current
date and time. Once you set the date and time. this
information will be recorded on the tape along with the
audio signal during recording, allowing you to check the
recording date of the tape during playback at a later time.
etting the Date and Time
1 with the unit stopped, press the CLOCK SET
button.
The year display begins to flash.
2 Press 9 (-) or 0 (+) to decrease or increase the
displayed item, then press the CLOCK SET button.
The next item begins to flash
3 Repeat step 2 until ail items have been set.
For greater accuracy, set the seconds display to zero,
then press the CLOCK SET button in synchronization
with a timecast (from the telephone or other time
source).
To confirm the date or time
Press the PRESENT button to display the date, the day of
the week or time. When pressing the PRESENT button
once, the date is displayed, when pressing twice, the day
of the week is displayed and when pressing three times,
the time is displayed. To return to the original counter
display, press the COUNTER MODE button
Time display
The time is displayed in 12-hour format.
Midnight and noon are displayed as follows
Midnight: 12:00 AM
Noon: 12:00 PM
Built-in clock
This unit's built-in clock operates using a quartz oscillator,
and time variations caused by changes in temperature,
etc., may accumulate. For precise recording of hour,
minute, and second data by the built-in date function, it is
recommended that you set the clock once a week.
Precautions when setting the clock
* Set the clock while the tape is stopped
* Although this unit’s clock automatically adjusts for leap
years and long and short months, do not enter a date
which does not exist.
The day of the week is displayed as follows:
Note
This unit uses a back-up battery to keep the clock running
when the power is turned off. The life of the battery under
normal use is approximately seven years. When the battery
Starts to run down, the clock will stop operating normally.
When this occurs, have the battery replaced at your dealer
or nearest Sony Service Center (a battery replacement fee
is required).

SBM (Super Bit Mapping) Function
During anatog recording, the SBM function lowers noise
within the frequency band to which to the human ear is
most receptive to noise, thereby, sharply expanding the
auditory dynamic range of the recorded signal
To activate the function, turn on the SBM switch when
recording an analog source through the analog (LINE IN)
connectors except when long-play mode (32 kHz) is
selected.
High-precision pulse A/D converter
The DAT deck uses a pulse A/D converter and decimation
filter to convert an analog signal into a quantized 24-bit
digital signal. DAT, like CDs, uses 16-bit quantization, and
thus the 8-bit difference results in more precise
quantization, more signal information and less quantizing
noise than 16-bit quantization. During conversion of the 24-
bit data to a 16-bit DAT recording signal, the SBM function
boosts sound quality by reintegrating into the 16-bit signal
4 bits of signal information that would normally be lost
Applying the principle of human hearing
The SBM function applies the principle of human hearing in
the reintegration of signal information. The auditory range of
the human ear is generally considered to be 20 Hz to 20
kHz; hearing sensitivity, however, shows greater sensitivity
to the range between 3 kHz and 4 kHz, and lower sensitivity
to frequencies above and below this range (see Fig. BN )
This principle applies also to quantizing noise as well. By
reducing quantizing noise in this particular range. signals
can be recorded to produce more expansive sound than is
possible by a uniform reduction of noise over the entire
audible range.

Noise-shaping filter
The SBM function uses a noise-shaping filter (see Fig B)
with a frequency response similar to that of the human ear
to reduce quantizing noise within the most sensitive
frequency range, and to feed back the quantizing error
(that is normally lost) back to the input signal, re-integrating
the low-end bit information with the high-end bit information
(see Fig. BY} )

lithium battery (BAT301) or the clock IC (IC330) ordisconnecting
CN151 on removing the front panel assembly the clock is reset.
(In spite of pressing PRESENT button, the data indication be-
comes “— —¥ ~-M——p”
At this time, check the back-up function by the procedures given
below.
(1) Connect DC voltmeter to TP (BATT+) and TP (BATT -) on
the main board.
(2) When the power is off, the voltage value of the item (1) should
be less than +30 mV.
(When the voltage value becomes +30 mV or more, Check
around IC330 or replace 1C330.)
(3) When the power is on, the voltage value of the item (1) should
be less than 0 mV (— (minus) indication).
(When the voltage value becomes + (plus) indication, Check
around D321 or replace D321.)
(4) When the above voltage values are normal, set the preset date
and time (year, month, day, day of the week, hour, minute,
second) according to the instruction manual.
(5) After setting the time on the item (4), turn power off and turn
power on several seconds later, and check the clock works
normally.
Back-up Battery Replacement
The life of the back-up battery under normal use (normal tempera-
ture, normal humidity) is approximately ten years or more. (On the
instruction manual, described “approximately seven years”.)
Be careful about the following points on the battery replacement.
* Repair the cause of the battery wastage by performing mentioned
above “Clock IC Back-up Check”.
* The open-circuit voltage of the replaced battery is 3.0 V or more
as the new one, and when it is 2.0 V or less, it is completely
consumed, replace it with new one.
« Afterthe battery replacement, perform “Clock IC Back-up Check”
again and set the time.
Clock Frequency Adjustment
Adjustment Procedure:
1. Connect a frequency counter to pin ® of 1C330 and GND on the
main board.
2. Turn power on and confirm that the reading on the frequency
counter is 2048.00 + 0.02 Hz. (in normal temperature)
3. Perform “Clock IC Back-up Check” described above.
* Time setting procedure described on page 9.
