User Manual


The BT-105 is the name of the module used on classic AirTurn two and four pedal units. This screen shows the power and LED indicator light on the back of the BT-105 module.

On-screen Keyboard

It may surprise you that when you are using a Bluetooth foot pedal that the iOS on-screen keyboard does not appear. This is because most Bluetooth foot pedals mimic a computer keyboard resulting in iOS hiding the on-screen keyboard. You can cause the on-screen keyboard to appear by pressing the red power button on the back of the module.


This screen features numbered steps you can take to power on your device as well as pair and configure it for use. Tap on each step to see an animation of the LED status indicator.


You can also read the manual for your product right from this screen. Tap on the "Manual" option in the upper right corner of the screen.
