This device complies with Part 15 of the FCC Rules. Operation
is subject to the following two conditions: (1) this device nay
not cause harmful interference, and (2) this device must
accept any interference received, including interference that
may cause undesired operation.
Changes of modifications not expressly approved by the party

Note: 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 resi-
dential 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 interfer-
ence to radio communications. However, there is no guarantee
that interference will no 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 output on a circuit different
from that to which the receiver in connected.
-Consult the dealer or an experienced radio/TV technician
for help.
A shielded cable must be used when connecting a peripheral
to the serial ports.
