Pay attention to the power load of the outlet or prolonged
lines. An overburden power outlet or damaged lines and
plugs may cause electric shock or fire accident. Check
the power cords regularly. If you find any damage,
replace it at once.
Proper space left for heat dissipation is necessary to
avoid damage caused by overheating to the device. The
long and thin holes on the device are designed for heat
dissipation to ensure that the device works normally. Do
not cover these heat dissipation holes.
Do not put this device close to a place where a heat
source exits or high temperature occurs. Avoid the
device from direct sunshine.
Do not put this device close to a place where it is over
damp or watery. Do not spill any fluid on this device.
Do not connect this device to any PCs or electronic
products, unless our customer engineer or your
broadband provider instructs you to do this, because any
wrong connection may cause power or fire risk.
Do not place this device on an unstable surface or
support.

2 Hardware Installation
Step 1 Connect the DSL port of the device and the Modem
port of the splitter with a telephone cable. Connect the
phone to the Phone port of the splitter through a
telephone cable. Connect the incoming line to the
Line port of the splitter.
The splitter has three ports:
Line: Connect to a wall phone port (RJ-11 jack).
Modem: Connect to the DSL port of the device.
Phone: Connectto a telephone set.
Step 2 Connect the LAN port of the device to the network
card of the PC through an Ethernet cable
(MDI/MDIX).
Note:
Use twisted-pair cables to connect with the Hub or switch.
Step 3 Plug one end of the power adapter to the wall outlet
and connect the other end to the Power port of the
device.
Connection 1: Figure 3 displays the application diagram for
the connection of the device, PC, splitter and telephone sets,
when no telephone set is placed before the splitter.
