Conformance notices
The RT complies with the radiated emission limits for 47 CFR 15.109:2010 class A of
Part 15 subpart B of the FCC rules, and with the emission and immunity limits for class
A of EN 55022. These limits are designed to provide reasonable protection against
harmful interference in business, commercial and industrial uses. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following:
• Re-orient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
The RT incorporates a GNSS receiver. No GNSS receiver will be able to track satellites
in the presence of strong RF radiations within 70 MHz of either the L1 GPS frequency
(1575 MHz) or L2 1228 MHz.
The RT conforms to the requirements for CE.
