Transmitter

1. Battery Compartment (Next to Power Jack) – Accommodates two AA batteries. To avoid damage to the
transmitter, observe proper polarity when inserting batteries.
2. Power Jack (DC in 9V) – Connect the optional 9V DC, 500mA external power supply to this jack. It is not
necessary to use this jack if you are using batteries to operate the transmitter.
3. Battery Status LED (Low Bat.) – The LED indicator will begin flashing red when battery capacity is running
low.
4. Wireless Connection Status LED (Connect) – This green LED displays the current state of the wireless link:
On – Connected
<
5. Power Switch – This switch powers the unit on and off. If both AC and battery power are available, the transmitter
will opt for AC power in order to preserve battery life. When not in use, be sure to turn off the transmitter to
preserve battery life.
6. MIDI Input
– Attach the included MIDI breakout
cable to this jack and connect the 5-
pin MIDI plug to your keyboard's MIDI
output.
7.
Wireless
(Connect) – The MidAir transmitter
and receiver will usually establish a
wireless connection automatically.
Under some
excessive interference, distance, or
other factors may cause the controller
and receiver units to lose contact. If
the wireless connection fails and the
transmitter and receiver are within a
range of 30 feet, press the wireless
connect buttons on both units to
re-establish connection.
If you're using more than one MidAir wireless setup, you might find yourself in a situation where you've inadvertently
linked a transmitter to the wrong receiver unit. This will result in your MIDI data being routed to the wrong
destination. If this happens, you can simply press the wireless connect buttons on both devices to "re-introduce"
them to each other.
This button is recessed to avoid accidental activation. Use a bent paperclip, pen, or other small object to press the
button.
