You access the 2nd and 3d row by pressing the device name at the top right hand corner of the screen, next to the power button.
Don’t feel bad that you couldn’t find this in the manual. After much searching, I finally found it on page 6, paragraph 4, where is gave these cryptic instructions:
The selected modes (up to 8 characters in each label key) are displayed. Labels change in the order from the first stage to the third stage and come back to the first and so on each time you press the mode display key.
