4. Directions for use
If your modem does not work well or the connection is extremely slow, try connecting
again. The quality of the telephone connections in many areas is not always optimal.
4.1 Internet
You may need to create a 'Dial-up' connection in order to connect to your ISP (Internet
Service Provider). This is a standard Windows feature and is usually installed
automatically after double-clicking on the Internet icon.
See the Windows on-line help for more information.
Some Internet providers provide a complete software package for Internet access,
making your system suitable for the Internet.
4.2 Indicators
The USB modem has a number of indicators which show whether or not the modem
has made a connection. The indicators have the following significance:
OH Off hook Lights up once a connection has been made.
READY - Lights up once the modem is connected to the
USB port.
Tx/Rx Transmit / Receive Flashes whenever data is sent and received.

9. Conditions for 56K connection
Under certain circumstances your 56K USB Modem can receive data at a speed of a
maximum of 56,000 bits per second. If it is not possible to connect at 56,000 bps, the
modem will switch back to a lower speed automatically.
A speed of 56,000 bps is only possible
for receiving data under the following
circumstances:
•You are connected with the Internet;
•Your Internet provider has a 56,000 bps compatible connection station at the
number you are calling;
•You are connected with the Internet provider via a modern (digital) telephone
exchange. If unsure, ask your telephone company;
•You are using a direct analog outside line and are not connected via an internal
telephone system or ISDN.
The maximum speed under all circumstances and
for sending data is 33,600 bps.
Note: The speed depends on the quality of the telephone line. The 56K USB
Modem will reduce the speed if the connection is poor.
