Conformance notices 
The RT3000 v4 complies with all emissions and immunity limits for the standards stated on the Declaration of 
Conformity. 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 GPS frequencies L1 (1575 MHz) or L2 (1228 MHz). 
The RT3000 v4 conforms to the requirements for CE.
