1.2 Safety Precautions
Follow the following instructions to prevent 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 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 damage caused
by overheating to the device. The long and thin holes on the device are

2
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 exists 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
To connect the device, do as follows:
Step 1 Connect the ADSL 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
