DP 2310 Wi-Fi Switch System
Guide
Created on 12/3/2002 11:45 AM
This equipment has been tested and found to comply with the limits of a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a residential environment. This equipment generates,
uses, and radiates radio frequency energy, and if not installed and used in accordance with the
instructions, may cause harmful interference. However, there is no guarantee that interference will not
occur. If this equipment does cause interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to correct the interference by one
of the following measures:
•
Reorient or relocate the receiving antenna.
•
Increase separation between the equipment and receiver.
•
Connect the equipment to an outlet on a circuit different from which the receiver is connected.
•
Consult the dealer or an experienced radio/TV technician.
1.3.1
Declaration of Conformity for RF Exposure
The DP 2310 Wi-Fi Switch has been evaluated under FCC Bulletin OET 65C and found to be compliant
to the requirements set forth in CFR 47 15.247 (b) (4) addressing RF Exposure from radio frequency
devices. The equipment must be positioned not less than 2m from your body or nearby persons. This
distance must be maintained in order to ensure compliance with RF exposure requirements.
1.3.2
Cautions and Warnings
CAUTION:
The radiated output power of this product meets with FCC radio frequency (RF)
exposure limits. However, this equipment should be used in such a manner as to minimize the
potential for human exposure. Table 1.3.3 lists the radiated RF energy characteristics of the DP
2310 Wi-Fi Switch.

Notes: 1) The directional beams from the DP 2310 Wi-Fi Switch are not fully formed until greater
than 30 meters from the antenna, where conventional EIRP calculations apply. 2) The values in the
above table were computed using numerical analysis of the antenna array pattern.
