Internet link action buttons

When dial-up Internet access is enabled, three

buttons on the Home page give you manual

control over dialing the modem:

•

Connect

– If the Internet link is down, click

this to make a connection.

•

Disconnect (Abort)

–

If the Internet link is up,

click here to disconnect immediately. While

the unit is dialing or in the process of

connecting the button will display

Abort

but

the result is the same.

•

Sometimes you need to

prevent the unit from attempting to make

automatic connections to the Internet. You

can disable automatic dialing by entering

the management password and clicking

Disable

. After the Internet connection has

been disabled the unit will no longer

attempt to dial out when users try to access

the Internet. However, it will still be

possible to force a connection by clicking

Connect

While automatic dialing is disabled the

button text reads

Enable

; enter the password

and click here to reenable.
