System Requirements - Windows 98 or later.
Compliant with USB 1.1 requirements for bus powered devices. USB
Hub supports low power or self powered USB devices (each USB port

Pre-installation Guidelines - Before installing your DPA,
observe the following guidelines:
CONNECTION WARNING - Never connect the DPA directly to the
telephone line or telephone wall outlet. Use the procedures in
this User's Guide to avoid damaging your DPA.
USB DRIVERS - The DPA uses standard Microsoft drivers. When
installing the DPA for the first time you will be prompted by the
computer to install/load drivers. Follow the prompts to identify the DPA
to your operating system.
TELEPHONE LEVEL SWITCH - Set the Telephone Level switch on
the DPA for the telephone you are using (refer to the Level Switch
Setting Table on page 14). Switch setting #3 is used on the majority of
digital telephone systems.
TELEPHONE SET VOLUME CONTROL - The Telephone Set Volume
Control (handset and/or speakerphone volume) may impact your
connection speed. KONEXX recommends that the volume control be
set in the mid-range for most telephone sets. Some AT&T/Lucent /
Avaya sets may require the volume set at a lower level.
SPEAKERPHONES - If the attached telephone has speakerphone
capability, do not use speakerphone mode. Speakerphone mode
disconnects the handset jack used by the Modem Konnector to send
and receive data.
DIALING - Configure your modem for Tone Dialing (Go to
Start…Settings…Control Panel…Modems…Dialing Properties…click
on TONE DIAL ).
MODEM SPEAKER CONTROL AND VOLUME - The telephone
handset is deactivated when your modem is in use. You can use the
“M1” command to enable the modem speaker and the “L3” command
to set its volume. You can then "listen in" on dialed calls to monitor
their status. Refer to your modem manual for more information.
