1 Make sure that the AUTO indicator is lit. If it is not,
press the START ID AUTO button to light it.
When turning on the power and inserting a cassette
with its safety tab at the record-possible position, the
AUTO indicator lights automatically.
In time recording, this indicator will be the same as the
one before the power is turned off. Start IDs will be
recorded automatically when the AUTO indicator lights.
2 To start recording, press the @REC button, then
press the PAUSE or » (play) button.
When the non-signal level lasts for more than 3 seconds
and a selection then starts, the start ID is written for 9
seconds (18 seconds in the long-play mode).
While a start ID is being written, the [START [D] indicator
blinks on the display.
Why 9 seconds or 18 seconds are necessary for writing
a start ID
A start ID requires 9 or 18 seconds to allow to be detected
when rewinding/fast-forwarding a tape. (The speed is 200
times as fast as that of normal tape operation.)
After the start ID is located, the tape returns to the
beginning of the start ID if necessary, and playback starts
from the beginning of the selection,
If the signal level stays very low for more than 3
seconds
If there is a portion of very low volume level during a
selection, a start ID may be written even in the middle of the
selection. An unwanted start ID can be erased later. (See
page 23).
When the portion between selections is not clear
The start ID position may not coincide exactly to the
beginning of the selection. To shift the start ID position, see
"Shifting Start |Ds' and Program Numbers Position" on page
25.
