there are many items to align with five points (F1, F2, F3, F4,
F5) except "Frequency", "Mic Sense", "SQL/RSSI", and "Bat-
tery". The value of each parameter can be changed to desired
position by "" / "" arrow key for up/down, direct number
input and drag the mouse.
To enter the Basic Alignment Mode, select "Basic Alignment"
