Identifying Radio Controls 
 Programmable Features 
 
Any reference in this manual to a control that is “preprogrammed” means that the control must be programmed by a 
dealer or qualified radio technician using the radio's programming software, in order to assign a feature to that control. 
 
The programmable buttons can be programmed as shortcuts to radio functions or preset channels/groups depending on 
the duration of a button press: 
• Press – Pressing and releasing rapidly. 
• Long press – Pressing and holding for the preprogrammed duration (between 0.25 seconds and 3.75 seconds). 
• Hold down – Keeping the button pressed.
