The parameters, which may be changed, and their margins are shown in the
following tables. To change a given parameter turn the rotary selector [9] until the field
is activated (it will appear shadowed) and then press. The value of the parameter will be
activated and may be changed by turning the rotary selector. When the value you want
appears, press the rotary selector [9] to validate it.
