The Accuracy of the Digital Linear Counter
Since the counter is not a digital clock, the number will differ
from the actual elapsed playback or recording time by a few
minutes, depending on such factors as tape length and hub
size.
When decks A and B are operated at the same time, slight
differences in tape length (even in the case of identical tape
types) and running speeds will result in a difference of a few
minutes between both counters.
Note on Memory Play/Stop
In actuality, the tape is rewound to slightly short of 0.00.
Do not turn off the power while using the counter
Turning the power off, then on again resets both counters to 0.00.

What is the Dolby HX PRO system
The Dolby HX PRO system provides linearity in high-range
frequency response during recording. Tapes recorded with
this system retain the same high quality even when played

Bias current" High
Established bias current
As shown above, characteristics such as output level and
distortion differ widely according to the bias (high-

current is susceptible to variations in certain recording
signals (see diagram below) which may cause fluctuations
in frequency response, distortion, or other unwanted
characteristics.

With the Dolby HX PRO system, the effective bias amount

cassette being used when the power was turned off.
However, for Relay Recording or Relay Play, recording or
playback on deck B always starts from the front side.
For single-deck recording
Be sure that only one cassette is inserted into either deck A
or deck B for single-deck recording. If a second cassette is
inserted and the DIR MODE switch is set to = or =,
Simultaneous Recording will occur and both tapes will be
erased.
Make sure the cassette holder is closed
If the cassette holder is left open, recording or playback will
not activate at the desired time.
Keep the POWER switch on the unit on
When the timer is set, the power of the unit will be cut off.
However, the POWER switch must be on to start the timer-
activated operation.
When the timer-activated operation is completed
Set the TIMER switch on the unit to OFF. If the
TIMER switch is left at REC, the unit will automatically start
recording the next time the power is turned on, and the
previously recorded material may be erased.

Cleaning the Heads and Tape Pa
Clean all surfaces over which the tape travels after every
ten hours of operation to guard against:
— low-quality sound
— a decrease in sound level
— excessive wow, flutter or drop-out
— incomplete erasure
— impairment of recording function
To obtain high-quality recorded sound, cleaning before
every recording is recommended.
1 Keeping the power on, turn the volume control on the
amplifier to minimum.
2 Press the # button to open the cassette holder.
