1.2 Safety Cautions
Follow the following instructions to protect the device from risks and damage caused by fire or electric power:
Use volume labels to mark the type of power.
Use the power adapter that is packed within the device package.
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 any damage caused by overheating to the device.
The long and thin holes on the device are designed for heat dissipation to make sure the device works normally.
Do not cover these heat radiant 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 is over damp or watery. Do not spill any fluid on this device.
Do not connect this device to any PC or electronic product, unless our customer engineer or your broadband
provider instructs you to do this, because any wrong connection may cause any power or fire risk.
Do not place this device on an unstable surface or support.

2 Hardware Installation
Step 1 Connect the Line interface of the device and the Modem interface of the splitter through a telephone cable.
Connect the phone to the Phone interface of the splitter through a cable. Connect the incoming line to the
Line interface of the splitter.
The splitter has three interfaces:
– Line: Connect to a wall phone jack (RJ-11 jack)
– Modem: Connect to the ADSL jack of the device
– Phone: Connect to a telephone set.
Step 2 Connect the LAN interface of the device to the network card of the PC through an Ethernet cable
(MDI/MDIX).

Figure 2 (with a telephone set before the splitter)
In the actual application, connection 1 is recommended.
I
Note:
When connection 2 is used, the filter must be installed close to the telephone lines. Do not use the splitter instead of the filter.
Installing a telephone directly before the splitter may lead to a failure of connection between the device and the
office central, or cannot access into the Internet, or slow the connection speed. If you really need to add a telephone
set before the splitter, you have to add a microfilter before connecting to a telephone set. Do not connect several
telephones before the splitter. Do not connect several telephones with the microfilter.
