Digital Control DIGITRAK FALCON F1 SINGLEBAND User Manual page 4

Interference levels change with time and with even minor changes in location.
The frequency optimizer is not a substitute for prudent operator judgment. If
performance drops while drilling, consider switching to the other selected
band (not available on the Falcon F1) or use Max Mode.
An A on the screen can indicate signal Attenuation due to the presence of
excessive interference, which can make depth readings inaccurate.
Attenuation is normal in shallow depths less than 8 ft (2.4 m). If the signal
strength is also flashing; this indicates extreme interference. Depth and
locate points may be compromised and the locator will not calibrate.
Interference is classified as either active (generating electro-magnetic signals)
or passive (material that can conduct or block electro-magnetic signals).
Sources of interference may include:
Active
Traffic signal loops
Buried dog fences
Cathodic protection
Radio communications
Security systems
Microwave towers
Power, phone, fiber-trace and cable TV lines
Passive
Metal pipes
Rebar
Trench plates
Chain-link fences
