deck I. The method used to set relay playback
mode involves stopping the motor of one or both
decks by the relay play switch, and putting one of
the decks into playback standby status (*1) in
advance.
Deck I is switched to playback mode when the
deck I PLAY button is pressed while in relay play-
back ready status, and deck II is switched to play-
back standby status (*1) when the deck II PLAY
button is pressed after that. When deck I stops
again (*2), the deck I motor stops turning (*3) and
the deck II motor starts up to switch deck II from
playback standby mode to regular playback mode.
That is, playback mode is relayed from deck I to
deck II, and the operation is the same when play-
back mode is relayed from deck II to deck I. This
operation can be executed repeatedly by simply
pressing the PLAY button of one deck while the
other deck is in playback mode.

The tape transport units feature a power assist
mechanism where capstan torque is used as a
source of drive power to move the head base. If
the PLAY button is pressed while the motor is
stationary, the capstan does not come in contact
with the pinch roller, nor does the head come in
contact with the tape.
Relay playback can be activated when either
RELAY PLAY indicator I or II is on, or blinking
on and off.
*1. PLAY button is in pressed status with the motor off.
*2. When the deck playback detector switch is turned off.
*3. Motor does not stop if the deck FAST detector switch is on.
@ Relay playback mode start conditions
(1) The COPY switch must be off.
(2) Deck II must not be in recording or recording-
pause mode.
(3). Both decks must not be in playback (or
playback-pause mode together.
The PD4061 is receptive to RELAY PLAY inputs
only when the above conditions are satisfied. The
subsequent outputs are listed in Fig. 12-3.
@ Relay playback mode cancellation conditions
(1) RELAY switch pressed a second time.
(2) COPY switch pressed (switched on).
(3) Deck IH switched to recording or recording-
pause mode.
Relay playback mode is cancelled, and RELAY
indicator I or II is switched off when any one of
these conditions is met. If the FAST detector
switch comes on during relay playback mode, the
corresponding motor output is switched to H level
(but only while the detector switch is on). That is,
the deck which is not in playback mode can be
switched to fast forward or rewind mode.
