4.2 Using
To be more easy to use, the remote control unit give direct access to the evice
parameters, there is no navigation.
It is divided in four parts: Common, CD player, Amplifier, Tuner (See section 4.1 for
details).
Two key are common to all airn devices:
Because short push and long pushs are distinguished, it is easier to turn on and off
all cairn devices at the same time (It is impossible to turn on a device and turn off
another one with the same push).
Turn off the device to avoid bad handling.
Use two 1.5 Volt cells size AAA (or LR03).
NOTE: For more details about the informations displayed by the “DISPLAY” key,
please refer to section 6.9.
Replacing the cells
-The “DISPLAY” key displays some inofrmations.
Consecutive pushs make scroll different screens.
-The “POWER” key controls every device at the same
time.
A short push turn them all on, while a long push turn them
all off.

In chapter 2 you have connected your .
Each time you turn on , the evice scans the option connectors and the RS-232
ports to detect the options and other devices linked to it.
If you have connected a new option into, or a Fog3 to the connector “Master” of
, the menu is updated to match with your new configuration.
For example, if you have connected a DAC option, you will see in the audio
connector list some new audio connector like “DAC coax1”, “DAC coax2” and
“DAC opt”.
Then you can create some sources that use these connectors.
NOTE: If you turn off your device unconnecting it from main supply without having
put it in sleep mode, the last changes will not be stored. Because has a low
consumption when powered off, you should use the right button to turn it off
