CHANNEL Tuning CONFIGURATION

In CHANNEL-FREQUENCY mode, when the instrument works in channel
tuning, if you press the CONFIG key [14] you will access the first page of the
configuration menu of the parameters relating on this mode (Fig.23).
The parameters which may be changed and
their values range are shown in the following table.
The parameters are different depending on the
channel, whether it is digital or analogue.
To define a CHANNEL as DIGITAL or
ANALOGUE, you should go to the EDIT
CHANNEL option that is in the GLOBAL
CONFIGURATION menu (see paragraph 4.2.1).
To access the second page of the GLOBAL
CONFIGURATION screen, press again the CONFIG
key [14] (Fig. 24).
To change a parameter value, turn the rotary
selector [9] until the field is activated (it will appear
shaded) and then press the rotary selector, the
value of the parameter will be activated and you will be able to change it by turning the
rotary selector. When the value you want appears, press the rotary selector [9] to
validate it.
Numeric fields such as FREQ. AUDIO, are edited digit by digit, starting from the
lowest weight digit.
