5.19.1 SELECTING THE INTF GROUP
To select the INTF group, press up or down on the GROUP switch one or more times until "INTF"
appears in the display. At this point each time the SET/NEXT switch is pressed down, the next INTF
function will be displayed. The three functions in the INTF group are:
1. Type
2. Head
3. TLBO
Each of these three functions each has an additional menu layer beneath them containing more
functions, and may be thought of as subgroups within the INTF function group.
