The VHF NAV system provides options to se-
lect VHF NAV and DME frequencies. Located
on both instrument panels, a NAV TUNE switch-
light allows either FMS or manual VHF navaid
frequency tuning. With the FMS annunciator il-
luminated, the FMS allows the pilot to tune the
frequencies with the FMS CDU. With the MAN
annunciator illuminated, the VHF NAV control
head provides manual tuning.
