Transmitters with LAN or WLAN Interface
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. 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.
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:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Transmitters with WLAN Interface
This device has been designed to operate with a 2 dBi half-wave antenna.
Antennas with a gain greater than 2 dB are strictly prohibited for use with
this device. The required antenna impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and
its gain should be so chosen that the equivalent isotropically radiated
power (e.i.r.p.) is not more than that permitted for successful
communication.
This Class [B] digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe [B] est conforme à la norme NMB-
003 du Canada.
