Operation

Once the HM220d ADSL modem has been properly connected and configured, simply
open your Internet browser and you are instantly on-line. No logon procedures are
necessary. The modem should be left on at all times; there is no need to turn it on and off,
since PipeLock guarantees your security when you are not using the Internet.
The HM220d ADSL modem operates automatically and will rarely, if ever, require any
intervention from you. There are some special features of the modem, such as the
PipeLock, with which you should be familiar. You may also want to know more about
the modem LEDs, which indicate the current operating state and provide useful
diagnostic information.

ON (lit), OFF (unlit), flashing at a certain rate or blinking periodically to indicate activity.
The general purpose of each LED is described in the table on the next page.
