4.2.2 Declaration of Conformity
This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions:
• this device may not cause harmful interference
• this device must accept any interference received, including interference that may cause
undesired operation
⚠ Radiofrequency radiation exposure information: this equipment complies with the radiation
exposure limits prescribed for an uncontrolled environment for fixed and mobile use conditions.
