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 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.
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.

2Installation
2.1Hardware Installation
Step 1: Place the UGL2430-RTB to the best optimum transmission location. The best
transmission location for your UGL2430-RTB is usually at the geographic
center of your wireless network, with line of sign to all of your mobile stations.
Step 2: Connect the UGL2430-RTB to your wired network. Connect the Ethernet WAN
interface of UGL2430-RTB by category 5 Ethernet cable to your switch/ hub/
xDSL modem or cable modem. A straight-through Ethernet cable with
appropriate cable length is needed.
Step 3: Supply DC power to the UGL2430-RTB. Use only the AC/DC power adapter
supplied with the UGL2430-RTB; it maybe occur damage by using a different
type of power adapter.
