message has been played back and the specified interval time has elapsed
(point indicated in the figure), that message is repeatedly played back.
The repeat interval is recognized when playback of a message has been
completed (points A through D in the figure). The repeat interval specified at
that time (2, 4, 2.5, or 5 seconds) first elapses before the next message is
played back.

The message playback interval is recognized at each of points A through E
(where playback ends). The specified interval time elapses first before the
next message is played back.
The output command of a message is recognized at its leading edge and
when playback of the message has ended and the specified interval time has
elapsed (point indicated in the figure).
If more than one output command turns ON at the point indicated in the fig-
ure, then messages are played back according to the following rules:
1.
When a message has been played back once, the output command of
that message is masked.
2.
Of the messages whose output commands have turned ON and have
not yet been masked, the message having the lowest number is played
back.
3.
After all messages whose output commands have turned ON have been
played back (at this time, all the output bits of messages whose output
command is ON are masked), all the output commands are unmasked,
and the message having the lowest message number is played back.
Note Masking means to temporarily stop playback of a message so that another
message can be played back even while the output command of the masked
message is turned ON.
