Yes, you can fully power off the Bluetooth module of the IC Pad. While the device is turned on, hold the button for 10 seconds (keep holding the button even when the white light goes off). After 10 seconds you will notice the indicator light flashing red a few times, indicating that the module has been powered off, and the device will restart. To confirm that Bluetooth is fully disabled, you can go to the Bluetooth settings on your phone, and attempt to search for a new device, and the IC Pad will not appear there. To turn on the Bluetooth module again, simply follow the same steps: while the device is on, hold the button for 10 seconds.
