Operating the CDF-552

Series III and Fliteline Interface

1. Set the MODE SELECTOR to ANT. Note that the external ADF pointer moves to 90

° and stops.

2. If frequencies displayed are not the ones desired, rotate the FREQUENCY KNOBS until the desired

frequency is displayed on the bottom line of the display.

3. Press and release the FREQUENCY TRANSFER button. This exchanges the two displayed

frequencies. The desired frequency is now active.

4. Adjust the VOLUME control to the desired audio level and identify the station represented by the active

frequency displayed.

NOTE: An alternate tuning method is to press and hold the FREQUENCY TRANSFER button for

two seconds before releasing. This removes the standby frequency from the display and
the active frequency may be tuned by rotating FREQUENCY KNOBS. The system is
ready for immediate operation. If desired, press the FREQUENCY TRANSFER button for
two seconds again to restore standby frequency.

5. Rotate the MODE SELECTOR to ADF. Note that the external ADF pointers leave the 90

° parked

position and move to indicate the direction to the active station.

6. Rotate the MODE SELECTOR to BRG and read the magnetic bearing shown digitally on the lower line

of the display. Compare this reading with the other ADF displays to assure correct system operation.

7. Return the MODE SELECTOR to ADF for normal ADF operation.
