The Push To Call (PTC) switch allows the user to place a call to a number that has been 
programmed.  To meet GSM specification, pressing the PTC button with no SIM 
installed will cause the unit to initiate a “411” call.  The application provider will need to 
configure the emergency number for its region. 
 

 
The switch is used to initiate a geo-fence with a default radius of one-half mile.  This 
radius may be re-defined by the application provider and is retained in non-volatile 
memory.  
 

 
The User-Defined button is a programmable button that can be defined for various 
functions.  Some examples of these functions include:  generate a call to a number 
different from the PTC button, generate a geo-fence with different parameters than the 
geo-fence button, send an SMS of the current location to a cell phone, send the current 
location to the server, etc. 
 

 
The Mini-MT has two volume buttons for controlling the audio volume level.  These 
buttons are functional whether in a call or not.  The ‘+’ button is used for increasing 
volume and the ‘–’ button is used for decreasing volume. 
 

NOTE:  While you are on an active phone call, the volume buttons will 
function in both headset and hands-free mode.
