Multi Function Knob (MFK)

MFK is the on/off button of your radio. See Turning On the
Radio on page 7 for the procedure to power up and down the
radio.
In addition, there are programmable features available for MFK,
which are:
Mode Change – Turn MFK to scroll the channel or zone list.
Volume Change – Turn MFK to increase or decrease the
volume level of the speaker. Fast turn of MFK makes coarse
tuning of the volume level; slow turn of MFK makes fine tuning
of the volume level. The display shows the volume level and
bars to indicate the current level. The level of last selected
volume before the radio powers down remains the same when
the radio powers up.
The main display only shows the icon of secondary feature; the
main display does not show the icon of primary feature.
The radio by default is set to use the primary feature. Short
presses of MFK toggle it to work on either the secondary or
primary feature.
The secondary feature has an inactivity timer. This timer starts
when the secondary feature is left idle. Your radio returns to
primary feature when this timer expires.
If the MFK is set to operate only one feature besides On/Off the
radio, Volume Change should be the only feature applied to
MFK.
Consult your dealer or system administrator for the best options
available for MFK.
