system output. It should be noted that only a short press is needed to both turn on and arm/disarm the unit.
The button needs to be pressed and held for approximately 1 second in order to power off the unit. In the
power off sequence the active settings are saved and reloaded when the unit is power back on.

Gate/Trigger Input
The Gate/Trig input allows external signals to either trigger or gate output events depending on setup.
4.2.6
Clock In /Clock Out
The Clock In allows external synchronization with other instruments. Various clock frequencies can be applied to the
input when the unit is set to external clock mode. The Clock Out will output various frequencies as well as a T0
signal. These outputs are user selectable.
