1.4. FCC Compliance Information

This device complies with part 15 of the FCC Rules. 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.

Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.

NOTE: The manufacturer is not responsible for any radio or TV interference caused by
unauthorized modifications to this

equipment. Such modifications could void the user’s

authority to operate the equipment.

This product also complies with FCC Part 22, 90 and Part 95 Subpart J of the FCC rules
and regulations.

The Federal Communications Commission (FCC), with its action in ET Docket 93-62, has
adopted a safety standard for human exposure to Radio Frequency (RF) electromagnetic
energy emitted by FCC-certified equipment. This product meets the uncontrolled
environmental limits as stated in OET-65C (01-01) when operated in accordance with the
operation guidelines described in this manual. Proper operation of this radio device
according to the instructions in this publication will result in user exposure substantially
below the FCC recommended limits.
