Message record indicators
:
a) When
REC
goes Low:
If present, SE1 is played and LED flashes once.
Then, the LED stays On to indicate that a recording is in progress.
b) When
REC
goes High or when the memory is full:
If present, SE2 is played and the LED flashes twice, and then remains Off to alert the
user that the recording process has been completed.
Triggering of
REC
during a play, erase or forward operation is an illegal operation and will be
ignored.
7.1.2
Playback Operation
Two playback modes are executed by
PLAY
, which is internally debounced.
a)
Edge-trigger mode
: Pulsing
PLAY
Low once initiates a playback operation of the current
message. Playback automatically stops at the end of the message. Pulsing
PLAY
again
will re-play the message. During playback, the LED flashes and goes Off when the
operation stops. Pulsing
PLAY
to Low again during playback stops the operation. Under
these circumstances, the playback pointer remains at the start of the played message after
the operation is completed.
b)
Sequential Playback mode
: If
PLAY
is held Low constantly, all messages will be played
and looped from the current message to its previous message. This looping continues until
PLAY
is released. After each message, SE1 is played. After the last message has been
played, SE2 is played, and then device plays the first message again. During the entire
playback operation, the LED flashes. When playback stops, the playback pointer will be
placed at the start of the halted message.
Triggering
PLAY
during a record, erase, or forward operation is an illegal operation and will
be ignored.
7.1.3
Forward Operation
The
FWD
allows the user to move the playback pointer to the next message in a forward
direction. When the pointer reaches the last message, it will jump back to the first message.
Hence, the movement is in a circular fashion among the messages. The
FWD
is debounced
internally. The effect of a Low-going pulse on the
FWD
depends on the current state of the
device:
a) If the device is in power-down state and the current location of the playback pointer is
not
the last message: the pointer will advance one message and, if present, SE1 is played.
The LED flashes once.
