The ON-LINE flag turns ON when input refreshing is executed after the
mode selector switch of the Voice Unit has been set to ON-LINE.
The ON-LINE flag turns OFF the next time input refreshing is executed af-
ter a switch from ON-LINE to any other mode has been made.
•
Message output in progress flag (word n+5 bit 02) (valid in ON-LINE mode
only)
This flag turns ON when input refreshing is executed during message play-
back. This flag turns OFF when the next input refreshing is executed, pro-
vided the message has been played back and the specified repeat interval
time has elapsed.
•
