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.

 

 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.
