Applicable FCC and Licence Regulations - FCCID: DLB5LTT98
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions:
1.) This device may not cause harmful interference, and 2.) this device must accept any interference
received, including interference that may cause undesired operation.
The model ATU Outdoor Manual Antenna Tuning unit is FCC accepted within this certification as serving as
the final output stage.
FCC part 15 rules, Section 15.219 Operation in the band 510–1705 kHz.
(a) The total input power to the final radio frequency stage (exclusive of filament or heater power) shall not
exceed 100 milliwatts.
(b) The total length of the transmission line, antenna and ground lead (if used) shall not exceed 3 meters.
(c) All emissions below 510 kHz or above 1705 kHz shall be attenuated at least 20 dB below the level of
the unmodulated carrier. Determination of compliance with the 20 dB attenuation specification may be
based on measurements at the intentional radiator’s antenna output terminal unless the intentional
radiator uses a permanently attached antenna, in which case compliance shall be demonstrated by
measuring the radiated emissions.
