.1 Overview
・The term "trigger" refers to a signal which is used to control the timing for
recording start or stop.
・The term "triggering has occurred" refers to the state when such a signal has
activated recording start or stop.
・Trigger parameters for the various functions are set using the STATUS 2
screen or the DISPLAY screen.

source).
The manual trigger is always activated when the
MANU TRIG key is pressed,
regardless of other trigger source settings.
