information. If your Pavilion PC included this component when
originally purchased, it was factory installed, configured, and
tested for optimal use; no further adjustment is necessary. If you
are installing these components in a previously purchased
Pavilion PC, please consult online Help or the documentation
that came with your PC regarding device expansion, upgrades,
and warranty before proceeding.

Section One - Introduction

Your modem represents a new generation of PC communication peripheral devices, combining high
speed Data and Fax functions into a single device. It supports V.90 and K56flex technology for 56kbits/s
data transfer rates. This high performance modem connects your computer to all popular modems and
fax machines in use today.

How Does K56flex Work

V.90 technology allows users to receive data from their Internet Service Provider (ISP) at data
rates up to 56kbps. To make use of this capability, your ISP must support either the V.90 or the
K56flex standard. Your modem must connect to an ISP or corporate central site with a pure
digital connection to the telephone network to realize speeds reaching 56kbps. 56kbps cannot be
achieved in a connection between two end user modems because each uses an analog
connection.

Benefits of 56K Communications

For serious Internet users the increase in speed is dramatic, because the information that usually
makes you wait – graphics-heavy Web pages, sound, video, and other large files – now
downloads to your computer twice as fast as before. Upstream transmissions (mostly keystroke
and mouse commands from your computer, which require less bandwidth) continue to flow
quickly at the conventional rate of 33.6Kbps.

Modem Features and Compatibility

Your modem is compatible with the following standards.

V.32 (9600 bps) V.32bis (14400 bps)
V.22bis (2400 bps) V.22 (1200 bps)

Section Two - Troubleshooting

Your modem is designed to provide reliable and trouble-free functionality. However, should you
experience any difficulty, the information contained in this section will assist you in determining and
resolving the source of the problem. If you can not resolve your situation after reading this chapter,
contact your dealer or vendor for assistance.

Modem does not respond to commands

1. Make sure the modem is not configured with a conflicting COM port and IRQ setting. Check for
conflicts by going to the SYSTEM control panel and selecting the Device Manager tab. Then,
double-click on the modem icon to get a listing of modems that are installed on your computer.
Double-click on the listing for your new modem. This will show you the modem’s properties. If
Windows configured the modem correctly, the section labeled “Device status” should read “This
device is working properly.” If this is not the case, you might have a hardware resource conflict.
To correct this, click on the Resources tab to view and manually change your configuration to
avoid the conflict.

2. Make sure the modem is properly initialized by the communication software. Your modem may
have been improperly initialized by the software because you have selected an incorrect modem
type. Select "Lucent Based Data/Fax/Voice/DSVD Modem" in your application software.
Alternatively, you should use the “Generic Hayes Modem” option for data-only applications. You
may also be prompted to enter an initialization string” by the software. Use AT&F as your
initialization string.

Modem dials but does not connect.

1. Make sure the phone line is working properly. A noisy line will prevent proper modem operation.

2. Try connecting to another modem number to ensure the problem is not related to the answering
modem.

Modem makes a connection but no data appears on your screen.

1. Make sure all communication parameters (baud rate, data, stop, and parity bits) are properly
configured and are identical on both sides. Be certain hardware flow control (RTS/CTS - default)
is enabled in both the modem and the communication software.

2. Press the ENTER key several times. The remote system may be waiting to receive your data
before it begins.

3. Make sure the correct terminal emulation mode is being used in the software (refer to software
manual).

Modem experiences errors while on-line with a remote modem

1. Make sure Call Waiting is turned off.

2. Make sure RTS/CTS hardware flow control is enabled (do not use XON/XOFF software flow
control when transferring binary files).
