Information for United States Users
This equipment has been tested and found to comply within 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
ha
rmful interference in a residential installation. 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 t
o 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 and 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.
The
user is cautioned that changes and modifications made to the equipment without the approval of
manufacturer could void the user’s authority to operate this equipment.
Operation is subject to the following two conditions: (1) This device may not cause harmful interference,
and (2) this device must accept any interference received, including interference that may cause undesired
operation.
The radiated output power of the print server is far below the FCC radio frequency exposure limits.
Nevertheless, print server shall be used in such a manner that the potential for human contact during
nor
mal operation is minimized.
To
satisfy RF exposure requirements, this device and its antenna(s) must operate with a separation
distance
of at least 20 centimeters from all persons and must not be co-located or operating in conjunction
with any other antenna or transmitter. End-users must be provided with specific operating instructions for
satisf
ying RF exposure compliance.
Channel
The Wireless Channel sets the radio frequency used for communication.
- Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel
which provides the least interference and best performance. In the USA and Canada, 11 channel are available.
If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference.
- In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than
one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.)
- If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However,
most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join.
Note:This equipment marketed in USA is restricted by firmware to only operate on 2.4G channel 1-11
