Rotary Adjustment Knob
An alternate to the Arrow Keypad, the Rotary Adjustment Knob may be used to
adjust the current parameter. The step size is controlled by the position of the
cursor, however turning the knob faster will increase the step size. Pushing the
knob will perform functions similar to the NEXT key and switch to the next pa-
rameter in the currently displayed menu.
Second Level Menus (Function Key)
The second level menus (indicated in yellow above certain keys) are accessed
through the use of the yellow FUNC key. Pressing the FUNC key once and then
pressing the desired menu key will display the specified second level menu.
Pressing the FUNC key twice in succession will put the unit into Function Lock
mode, where the second level menus can be accessed without repeatedly
pressing the FUNC key. Pressing the FUNC key a third time will exit Function
Lock mode.
