3.4.2 General
Keypad
Operation
The CYD211 has two keypad operations: setting selection and data entry.
Setting Selection:
Allows the user to select from a finite list of parameter
values. During setting selection the
s
and
t
keys are used to select a
parameter value.
Enter
is used to accept the change and advance to the next
parameter.
Select
will cancel the change to that parameter and return to the
normal display.
Data Entry:
Allows the user to enter numeric parameter values using the
s
and
t
keys. Press the
s
key to increase the value of the setting, or press
the
t
key to decrease its value. Holding either key down for a few seconds
will cause the number to change at a faster rate. Once the correct parameter
value is entered press
Enter
to accept the change and advance to next
parameter. Pressing
Select
will cancel the change to that parameter and
return to the normal display.
Related setting selection and data entry sequences are often chained
together under a single setting sequence. To skip over a parameter without
changing its value press
Enter
before pressing an arrow key. To return to
the normal display in the middle of a setting sequence press
Select
before
pressing an arrow key. Changes “entered” before
Select
is pressed are kept.
