to power on your OP-1, slide the white power switch located on the right side of the device towards you. the display will light up and the OP-1 loads necessary system data.
to power off, slide the power switch away from you. data is always stored on-the-fly, so you don’t have to worry about saving your sound or recordings.
everything will still be there the next time you power on your OP-1 exactly the same as when you left it.
note: the more samples or other data you store on your OP-1, the longer the start-up process will be. it’s a good habit both for start-up time and for safety to back-up and clear your OP-1 occasionally.
the first thing you should do is to connect your OP-1 to a computer (or optional charger) via the USB port located on the right side of the unit.
make sure to keep your
OP-1 connected until you have fully charged the internal battery. this will be indicated by the same LEDs used for the VU meter.
to check the battery level, press the help key. the LEDs will light up to indicate the level. five lit LEDs is equal to a fully charged battery.

OP-1 has three ports located on the right hand side of the unit.

if you turn your OP-1 upside down,
you will find symbols and braille text that indicates I/O location.
