whether the wireless network function is enabled. 
How can I quickly restore the default settings of the terminal? 
To restore the default settings, press a nd hold the RESET button on the rear panel 
for over six seconds after the HG520c is pow ered on, and then release the button. 
What can I do if I cannot access the Internet through the terminal? 
Step 1
 Check whether the POWER indicator
 on the terminal is solid on. 
If the POWER indicator is off, perform further checks as follows: 
1.  Ensure that the terminal is turned on. 
2.  Ensure that electricity comes from th e socket and that the power input 
from the socket meets the requirements described on the label of the  
						

							
 14 
terminal power adapter. If the voltage is unsteady, for example, if the 
voltage is too high or too low, do  not use the terminal. Wait until the 
voltage restores to its normal level, and then use the terminal. 
3.   Ensure that the terminal is properly connected to the socket through 
the power adapter. 
If the POWER indicator is still off, contact an authorized maintenance 
center. 
Step 2
 After powering on the terminal, wait for about three minutes. Then, check 
whether the ADSL indicator on the terminal is solid on. 
If the ADSL indicator blinks for a l
ong time, perform further checks as 
follows: 
1.   Ensure that telephone lines ar e properly connected. Pay special 
attention to the connections between the telephone lines and the 
splitter. 
2.   Ensure that the terminal or telep hone lines are far from the electric 
appliances that generate strong ma gnetic or electric fields. Replace 
telephone lines when necessary. 
If the ADSL indicator still blinks and do es not turn solid on, contact your 
network operator. 
Step 3  Check whether the LAN indicator of the terminal is on. 
If the LAN indicator is off, perform further checks as follows: 
1.
  Ensure that the network adapter of the computer is enabled. 
2.  Ensure that the network cable between the terminal and the computer 
is properly connected. Remove and th en insert the network cable or 
replace the network cable when necessary. 
If the LAN indicator is still off, contact an authorized maintenance center.
Step 4  Check whether the driver for the netw
ork adapter is properly installed. 
Take a computer that runs Windows XP as an example. To check whether 
the driver for the network adapter is installed, do as follows: 
1.   On the desktop, right-click  My Computer, and then choose  Manage.
2.  In the navigation tree of the  Computer Management window, 
choose  Device Manager . 
3.  In the right pane of the  Computer Management  window, click 
Network adapters  to view the information  about the network adapter 
of the computer. 
If no network adapter is found or if a question mark (?) or an exclamation 
mark (!) is displayed next to the icon  of the network adapter, you can infer 
that the driver for the network adapter  is not properly installed. In this 
case, re-install the driver for the network adapter of the computer.

Step 5 Ensure that you have entered the corre
ct user name and user password that 
are required by the PPP dial-up software. 
The user name and the user passw ord are provided by your network

Step 6  Check whether you can use the PPP dial-up software to dial successfully.
If you cannot use the PPP dial-up softwa
re to dial successfully, perform 
further checks as follows: 
1.   Stop the PPP dial-up software and th en power off the terminal. After 
five minutes, power on the terminal, and then use the PPP dial-up 
software to dial again. 
2.   Restore the default settings of the terminal. 
If the problem persists, cont act your network operator. 
Step 7
 Check whether the proxy server of the Web browser is correctly 
configured. Take the Internet Explorer
 installed on a computer that runs 
Windows XP as an example. To check  whether the proxy server of the 
Web browser is correctly configured, do as follows: 
1.   Launch the Internet Explorer. 
2.  Choose Tools  > Internet Options . 
3.  In the Internet Options  dialog box, click the Connections tab. 
4.  In the Local Area Network (LAN) settings  group box, click LAN 
Settings. 
5.   In the Proxy server  group box of the Local Area Network (LAN) 
Settings dialog box, ensure that the  Use a proxy server for your 
LAN (These settings will no t apply to dial-up or VPN 
connections).  check box is cleared. 
Step 8
 Try to access multiple Web sites to check whether the terminal can access 
these Web sites. 
If the terminal still cannot access Web s
ites, contact your network service 
provider. 
What can I do if Web pages often cannot be displayed during Web page browsing 
and can be displayed after the terminal is restarted? 
Step 1  Ensure that the terminal and othe
r devices, such as telephones or fax 
machines, are connected to tele phone lines through a splitter. 
For details about how to install a splitter, see the related description in the 
manual. 
Step 2
 Ensure that telephone li
nes are properly connected. 
If the telephone lines are improperly connected, the stability of the 
network connection is affected.
