FCC: This device complies with Part 15.247 of the 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.
FCC: Unlicensed operation limits the radio power. High gain aerials may only be used to compensate for cable losses.
WARNING – EXPLOSION HAZARD
Do not disconnect the device while the circuit is live unless the area is known to be non-hazardous.
NOTE
The 925U-2 module ships from the factory as a bridged meshing radio. If communication with the older legacy 915U-2’s is required, radio’s operating mode can be changed with firmware.
