Select Keys
Within each function, there are a few parameters that can be selected for
setting or display purposes. The select keys allow the different parameters to
be chosen, without changing the value of any of the parameters.

Set Keys

Once any parameter is chosen, in order to set the value, the

and

keys

increase / decrease the value respectively. In most of the functions

described later, the

and

keys have an auto-repeat facility: press and

hold the key in order to advance quickly.

Note that the

and

keys are the only ‘ destructive ’ keys. The other

keys may be pressed to view or select any of the parameters without
affecting any change in the system.
