electromagnetic noise sources, such as a computer monitor
or television. Move away from the noise source if you
experience difficulty.
Technical information for e2e 2.0 wireless function:
Operating frequency : Fc = 3.28 MHz; Maxium field strength: –7
dB µA/m at 10m meters.
Changes or modifications not expressly approved by the party
responsible for compliance could void the users authority to
operate the equipment.
This Class B digital apparatus complies with Part 15 of FCC Rules.
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. FCC: SGI-WL002BTE
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. 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.
