Power/Volume
The knob at the top left corner of the GNS 480 controls power on/off and the radio volume. Push the
PWR/VOL knob in to turn power on. Pull the knob out to turn power off. When the power knob is
pulled out, a time-out message and counter will appear for five seconds. Turning the knob will con-
trol the volume of the COM radio, unless the NAV radio is active then the NAV volume is controlled.
A white border surrounding the Com, VOR, and XPDR information will flash and the values you can
change will be highlighted when each mode is activated.

Press the FN key to page through the available group of Functions that appear at the bottom of the
display. The "Smart" function keys located below each label will activate that function.

VTF mode, if you are within 45° of the inbound course and you are on the TO side, the "SUSP" mode
will turn off and return to normal sequencing. See page 99 for more details.
