Rear Panel
1. USB: The USB 2.0 port delivers power to the
keyboard and transmits MIDI data when connected
to a computer.
2. SUSTAIN: This input accepts a momentary-
contact foot pedal (not included). When pressed,
this pedal will sustain the sound you are playing
without having to keep your fingers pressing down
on the keys.
Note: The polarity of the sustain pedal is determined by the keyboard upon startup. When an
Oxygen 49 keyboard is powering up, the sustain pedal is assumed to be in the "up" (Off)
position. It is important that the sustain pedal is not pressed during startup, otherwise the pedal
will reverse its operation, and notes will sustain when the pedal is not pressed.
3. POWER ON/OFF: Use this switch to power the device on or off. When this switch is set to the
"on" position, Oxygen 49 is powered through the USB connection to your computer.
4. Kensington Lock: This connector is compatible with standard laptop-style Kensington
security cables for theft protection.
