4.2 Main menu items and their functionality − Overview
.
The scope of functions depends on the timer type connected! For
example, the number and representation of parameters or menu
items offered may be different, depending on the timer type used.
For this reason, the functionality of menu items or parameters will
not be dealt with in detail in this manual, which will rather be limited
to the handling of the BT 6.

be limited for your timer type!
