Once you begin viewing restrictions, you can view any additional frequencies for
the selected airport by rotating K. (Note: An arrow prompt displayed next to the air-

is covered in Section 3. To return to the NAVCOM page, press N.
Some frequencies in the NAVCOM page have tags which designate their usage:
‘tx’ – transmit only ‘rx’ – receive only
‘pt’ – part time frequency
To make any of the frequencies on the NAVCOM page the standby frequency:
1. Press
C
twice to activate the cursor in the GPS window.
2. Rotate
O
until the desired frequency is highlighted.
3. Press
E
to make the highlighted frequency the standby frequency. The cursor will auto-
matically advance to the next frequency on the list.
The GNC 300XL position page displays your present latitude and longitude, alti-
tude and a reference waypoint field. The altitude and reference waypoint fields are
selectable to configure the page to your own preferences and current navigation needs.
An altimeter setting field appears on the position page when you are within 30 nm
of a destination airport. The altimeter setting field allows you to define the current
barometric pressure, which is used by the integrity monitoring to cross check altitude.
Frequency restrictions on 124.60, showing range
of applicable radials from 130º through 309º.
