Tuning a radio frequency with the MFD/PFD Control Unit:
1) Press the NAV or COM Key on the Control Unit to enter a radio tuning mode.
2) Turn the FMS/NAV-COM Knob on the Control Unit to tune a frequency in the desired tuning box (large knob
for MHz; small knob for kHz).
OR:
Press the numeric keys to enter a frequency in the tuning box.
3) Press the Frequency Transfer Key to transfer the frequencies between the active and standby fields.
4) Press the FMS/NAV-COM Knob to transfer the tuning box between radios.
When using the numeric keys to tune a frequency, at the first key press the first digit of the frequency in the
tuning box is highlighted. Frequencies may then be entered by the digit keys or by a combination of FMS/NAV-
COM Knob and numeric keys. While editing the frequency field, the small FMS/NAV-COM Knob can also be
used to change the value of the highlighted digit.
After each key press, the highlighted digit proceeds to the next position (Figure 4-20); the
BKSP Key can be
used to back up through the numbers. Rotating the large FMS/NAV-COM Knob also moves the highlighted
digit right or left. Pressing the Decimal Key begins entry of kHz frequency digits.
