Identifying Radio Controls

English

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.
