Appendix A. FCC notifications

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. This device
must be operated as supplied by Campbell Scientific, Inc. Any changes or modifications made to
the device without the express written approval of Campbell Scientific, Inc. may void the user’s
authority to operate the device.

CAUTION:
The MM2 transceiver has a maximum transmitted output power of 1 watt. It is recommended
that the transmit antenna be kept at least 23 cm (approximately 10 in) away from nearby
persons to satisfy FCC RF exposure requirements.

This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. 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 measures:

l

Reorient or relocate the receiving antenna

l

Increase the separation between the equipment and receiver

l

Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected

l

Consult an experienced radio/TV technician for help

l

Consult Campbell Scientific
