ISEDC STATEMENT:
Operation of 5150-5350 MHz is restricted to indoor use only.
This device contains license-exempt transmitter(s)/receiver(s) that comply
with
Innovation, Science, and Economic Development Canada’s license-exempt RSS(s).
Operation is subject to the following two conditions:
(1) This device may not cause interference, and
(2) This device must accept any interference, including interference that may
cause
undesired operation of the device.
The device comply with RF exposure guidelines, users can obtain Canadian
