There is no charge for a code assignment at this time. This code is assigned to the USER and does
NOT transfer with the aircraft when it is sold.
INSTALLATION TESTING
The following tests should be performed to verify the installation in the airplane is operating
properly:
1. Apply power to the unit and press the SELF-TEST button to initiate a SELF-TEST. Within
approximately four seconds an indication of a SELCAL decode should be received on all
annunciators simultaneously.
2. Using a ground test set such as the Avtech CTS-700 SELCAL/ATSCALL Ramp Test Set,
select the frequency for test on one of the communication transceivers to which the CSD-714
is connected. On the test frequency generate a SELCAL encoded signal of the code sequence
programmed into the CSD-714. Confirm that the appropriate annunciator lamp illuminates
and the chime is heard, if installed. Take the appropriate action to reset the unit. Do this test
for all SELCAL channels and for all radios connected to the CDS-714.
3. If possible, contact the agency which will be furnishing SELCAL service to the aircraft and
request a test call.
