devices: tension at the connectors is a fire hazard. 

Avoid damaging power cords.

  Arrange power supply cords so that 

they are out of the way.  Route them through areas where it is unlikely 

they will be walked on or objects rolled over them. 

Avoid placing the product near any heat source.

  Never place this 

product near any heat source.  This includes any kitchen appliances 
(ovens, toasters, etc.), heating vents, or any other heat source.  This is a 

fire hazard. 

Do not use the product near water.

  Never use this product anywhere 

near a water source or in a damp area.  Don’t use it near bathroom or 
kitchen water sources such as sinks or washing appliances.  Don’t use it 

near pools.  Don’t use it in a damp area such as a basement. 

Avoid stacking.

  Avoid stacking this item on top of or under other 

devices that can generate or radiate heat.  Such stacking can concentrate 

heat sources in a small area and creates a fire hazard. 

Use caution when moving the product.

Using your Access Appliance 

6.1  Using the Connection 

Your Access Appliance provides you with an “Always-On” connection to 
the Internet so simply start up your e-mail client, Web browser, 

newsgroup reader, or other Internet applications and use them as usual.   
Note: If you are concerned that someone may attempt to access your 
computer via the Internet, you can use any number of firewall or Internet 
security software tools to prevent remote access.   Another solution is to 
disconnect the computer cable or disconnect power from your Access 

Appliance. 
 

6.2 Disconnecting 

If you have any security concerns about leaving your PC connected while 
it is not in use, firewall software or equipment can be purchased at many 
computer retailers; or you can simply unplug the Ethernet cable from the 

PC until you need to access the Internet again.

Troubleshooting Connection Problems 

The 

P

 (Power) and 

S

 (Sync) LEDs should be ON; and you should see the 

T (Transmit) and R (Receive) LEDs flash when you attempt to browse the 

Internet. 

If the 

S

 or 

F

 LED is blinking or no LEDs are on, check all the hardware 

connections and cables (refer to 

Connecting to the Access Appliance

). 

If the 

P

S

, and 

D

 LED is ON, then the Access Appliance is functioning 

correctly; but it has not been enabled and you should contact your service 

provider for service activation. 

If this problem persists, contact your service provider for assistance.  (See 

also page 7 for a description of the Front Panel status LEDs.)
