Starting condition
Adjustment of playback of A/B-deck
If the A-deck or B-deck has half, the A-deck or B-deck
adjustment mode is accepted.
Either or both decks having halves are adjusted in the
order of Aand B.
Only the deck(s) and only the channel(s) which has
(have) not been adjusted is(are) adjusted at this time.
Normally, if playback of a channel is adjusted, the
REC EQ/BIAS are set again in the unadjusted condi-
tion.
If the playback modes of both A- and B-decks have
been adjusted, the adjustment is finished without ad-
justing anything.
If either deck does not have half, adjustment is

When
performing this operation, press the keys of
the receiver having the names of the above keys used
in the normal mode.
For example, since the [CCRS/CRLS] key is used as
the key for resetting in the normal mode, the [CCRS/
SRLS] key of the receiver is used for this purpose.
Since data cannot be output in series for the adjust-
ment in the system mode, the adjustment value is indi-
cated by the counter of the receiver.
Set the selector
of the receiver to TAPE at this time, however.
