During the course of navigating with the GNC 300XL, there may be times when
you need to quickly select a comm frequency while you are entering data in the GPS
window. Whenever data entry in the GPS window is interrupted by activating the
standby frequency field, the GPS field in use will become 'splatted', or blocked out.
Once the standby frequency has been entered, you may return to data entry by
pressing the C key. The cursor will return to the active GPS field at the point where
data entry was interrupted.
The GNC 300XL' s auto-tune feature allows you to quickly select any database
frequency in the GPS window as your standby frequency.
