When the battery is in CodeBug, it is always on even when it is sleeping. So to get CodeBug into the programming mode, you must:

• plug in CodeBug to your computer via USB

• then hold both buttons for at least 10 seconds (the LED display will turn off after 5 seconds so make sure hold the buttons for at least 5 seconds after that)

• then let go of button B, making sure you keep A pressed

• the programming indicator LED will begin to flash

• you can then load your programs as normal by dragging them onto the CodeBug device.
