adjacent LED indicating that the Shift function is active. To cancel the shift function before selecting
a blue-labeled function, press SHIFT a second time. The green LED goes off, indicating that the
Shift function is no longer active. SHIFT is also used to activate the hold function which disables
the data knob: the hold function is activated when you press SHIFT until the green LED goes off.
When you want to disable the hold function, repeat the above procedure; when the LED goes off,
the hold function has been reset.
