small
NAV

VOL/ID
Knob again to turn the Morse code off in the other radio.

Decoded Morse Code Station Identifier
– The NAV Frequency Box displays the decoded Morse
Code station identifier that is received from the navigation source. Audio verification of the selected
station identifier can be accomplished by selecting the corresponding NAV radio on the audio panel
and pushing the
NAV VOL/ID
Knob.

NAV VOLUME
– NAV radio volume level can be adjusted from 0 to 100% using the
VOL/SQ
Knob.
Turning the knob clockwise increases volume, turning the knob counterclockwise decreases volume.
When adjusting volume using the PFD or MFD VOL/SQ Knob, the level is displayed in place of the
standby frequencies. Volume level indication remains for two seconds after the change.
