Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital service, pursuant to
Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. Any changes or modifications made to this equipment may void the
user’s authority to operate this equipment. This equipment generates, uses, and can radiate radio frequency
energy. 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.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
All external cables connecting to this basic unit must be shielded. For cables connecting to PCMCIA
cards, see the option manual or installation instructions.
RF exposure warning:
The equipment complies with RF exposure limits set forth for an uncontrolled
environment. The antenna(s) used for this transmitter must not be co-located or operating in conjunction
with any other antenna or transmitter.
You are cautioned that changes or modifications not expressly approved by the party responsible for
compliance could void
your authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device mat not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause
undesired operation.
DGT Warning Statement
Article 12 Without permission, any company, firm or user shall not alter the frequency, increase the power, or
change the characteristics and functions of the original design of the certified lower power frequency electric
machinery.
Article 14 The application of low power frequency electric machineries shall not affect the navigation safety
nor interfere a legal communication, if an interference is found, the service will be suspended until
improvement is made and the interference no longer exists.
