MCU 2.75 / DSP 1.49
- FOUR PROGRAMMABLE FUNCTIONS: The KX2 now has four programmable functions, PF1-PF4, rather than one. These can be used to quickly access often-used menu entries. To set up a programmable function, locate the desired menu entry, hold PFn, then tap any of 1 through 4. Exit the menu. From then on, the menu function can be accessed using the associated PFn switch. If a menu entry has only two values (such as ON/OFF), accessing it via a programmable function will select the alternate value, then exit the menu immediately. This is especially useful with menu entries such as DUAL RX, VOX MD, ALT MD, and ATU DATA (see rev. 2.73, below).
