ADVANCED OPERATION (VOR NAVIGATION: AIR BAND)
Split Operation

VOR stations equipped with this capability typically are shown, on navigation charts, with the voice calling frequency in parenthesis above the navigation frequency.

rSet the desired VOR station’s frequencies in the NAV band (108.000 - 117.975 MHz) using the DIAL selec- tor knob or keypad.
rPress 
Ò 
. The “ 
” icon will blink, and the transmit frequency will appear on the display.
rNow set your radio’s transmit frequency, where the Flight Service Station will be listening for calls, using the DIAL selector knob or keypad.
rPress and hold in the 
key for 2 seconds to save the transmit frequency and return to the NAV band
frequency.
rPress and hold in the PTT switch to transmit on the split transmit frequency.
rRelease the PTT switch to return to the receive mode.
rTo disable the “Split” function, set the receiving fre- quency to any frequency outside of the NAV band (the “ 
” icon will disappear).
Note: A split frequency can be programmed into each memory channel independently. Set a transmit frequency before programming the memory channel, if desired. The split function on/off setting can also be programmed into a memory channel.
