F3Ci Operations Manual
Noise Cancel will commence with a single beep followed by 20
seconds of a series of two beeps and finishing with a three-beep
sequence.
Figure 17: Noise Cancel
During the 20 seconds, the detector scans the environment
searching for any electrical interference. Once detected, the F3Ci
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.

When the detector is first switched on the LEDs are deactivated. If
required, the LED display can be activated by pressing and holding
the Mode Select button and then pressing the Ground Balance
button. Upon the LEDs illuminating release both buttons. To
extinguish the LED display, repeat the process.
