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 25 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 25 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.
