Samsung NP940X3G-S02US - Manual (Page 134)

Appendix
134
When using IEEE 802.11a wireless LAN, this product is restricted to
indoor use due to its operation in the 5.15 to 5.25 GHz frequency
range. Industry Canada requires this product to be used indoors
for the frequency range of 5.15 GHz to 5.25 GHz to reduce the
potential for harmful interference to co-channel mobile satellite
systems. High power radar is allocated as the primary user of the
5.25 to 5.35 GHz and 5.65 to 5.85 GHz bands. These radar stations
can cause interference with and/or damage to this device.
The maximum allowed antenna gain for use with this device
is 6dBi in order to comply with the E.I.R.P limit for the 5.25 to
5.35 and 5.725 to 5.85 GHz frequency range in point-to-point
operation. (If fitted with 2.4G band or 5G band)
Low power, Radio LAN type devices (radio frequency (RF) wireless
communication devices), operating in the 2.4GHz/5GHz Band,
may be present (embedded) in your notebook system. This
section is only applicable if these devices are present. Refer to the
system label to verify the presence of wireless devices.
Wireless devices that may be in your system are only qualified for
use in Canada if an Industry Canada ID number is on the system
label.
