10. BROADCAST DELAY TIME AND BUSY OUTPUT ON/OFF SETTINGS
The delay time between message activation and the actual start of playback can be set to 0, 2, or 4 seconds
with the unit's rear-mounted Delay Time Setting switch. When repeat broadcast mode is selected by the
Playback Interval Setting switch, the busy output during the time intervals (except for "0 s" and "
∞ " settings)
can be set to "Make" (ON) or "Break" (OFF).
(Factory-preset to "0" seconds , and the busy output during intervals between repeated broadcasts to "ON".)
Should the beginning of playback contents be lost due to operational delays experienced by connected
external equipment, set the delay time to 2 or 4 seconds.
Note: If the delay time is set to 2 or 4 seconds, the Busy Output terminal is closed during the delay as well.
