Questions answered in QL120_A3 manuals
How do I program surface mount devices?
You can use the 9 built-in surface mount positions on the right side to press-fit and burn chips directly without connecting jumper wires, though this is not suitable for batch burning.
What does the LED1 indicator signify?
LED1 indicates that the user board power is active; it only lights up after ICD2/MCD2 establishes normal communication with the computer and supplies 5V voltage.
