During the 45 seconds, the detector scans the environment searching for any
electrical interference. Once detected, the F3 Compact will automatically select a
different operating frequency to eliminate or reduce the interference.
NOTE
The detector cannot be used for clearing operations during Noise Cancel. The coil
should not be moved during this procedure nor should metallic objects be brought
near the coil.
