3.2.9 Power Supply Loss
Note that if power is lost to the AFS-3 the output relay will relax because there is no voltage to energize the coil.
Additionally, there will be no logic voltage output since there is no power supply. Consider this and take necessary
steps if it becomes necessary to disconnect power from the AFS-3.

3.2.10 Safety Considerations
If the AFS-3 is connected so that loss of audio turns a transmitter off, the return of audio could turn the
transmitter back on. Operating and maintenance personnel should be mindful of this possibility and be
sure the transmitter is rendered inoperable before maintenance is begun on the transmitter, antenna, or
associated equipment.
