Free selection of listening 
source while recording 
The M51 also gives you the 
option to record from one 
source while listening to 
another. 
In this way, you could record a 
radio program to cassette while 
watching a DVD. 
To set this up, you simply have 
to select the listening source in 
the SOURCE menu once you 
have selected the recording 
source with Record, as 
described in the Select 
recording source section. 
Example: 
The above example shows a 
setting whereby you have 
chosen to watch a DVD 
(Listening: DVD/CD) while at 
the same time recording a radio 
programme (Recording: FM 
Tuner). 
Edit source name 
The I/O module offers you the 
option to select your own name 
for the inputs. In this way, you 
no longer have to remember 
which external device you have 
connected to which input. You 
can label it accordingly. 
Select the I/O source in the 
SOURCE menu whose name 
you want to change. You can 
choose between: 
Aux-1, Aux-2, Aux-3, Rec-In. 
You call this function by 
pressing the Setup button for 
approx. 2 seconds and then 
pressing the Source softkey. 
The following display appears: 
If you press the Edit Name key, 
you will move to the source 
name Editor function, as 
described in the next section.
