Fig. 4.1 shows the default display. The following
information can be obtained from the default display:

Note
The display is normally switched off to save
power. This increases the service life of the
batteries.
The display and lighting are activated as soon
as you turn or click one of the dials. If the
appliance is not used for more than one minute
the basic display returns and switches off after
approx. 10 minutes.
Note
When the dial is turned the values to be
displayed must first be called up by the radio
receiver unit. Until these values are obtained
only dashes instead of values will be displayed
(--). This generally takes up to two seconds.
Depending on the ambient conditions, it may
take up to 15 minutes until the current data are
called up by the radio receiver unit and are
subsequently displayed.
If dashes (--) are displayed continuously,
consult your expert technician.
