How can I switch the mode between USB HID and USB Serial?

There are two ways to accomplish this.

1: Scan the special barcode below:

2: Press the scan button combination within 3 seconds (to toggle between modes):

• 3 x Left Scan Button
•3 x Right Scan Button
•1 x Left Scan Button
•1 x Right Scan Button

So, in other words, L-L-L-R-R-R-L-R in 3 seconds. Then you will hear one beep or two beeps confirmation beeps. One beep indicates USB HID mode and two beeps indicates USB Serial.
