* IMPORTANT! In accordance with the ITU-T standard for 56K transmissions (V.90), U.S. Robotics 56 Kbps
modems are capable of 56 Kbps downloads. However, due to FCC rules which restrict power output of service
providers, current download speeds are limited to 53 Kbps. Actual speeds may vary due to line conditions and
other factors. Uploads from users to server equipment travel at speeds up to 31.2 Kbps. An analog phone line
compatible with the V.90 standard or x2 technology and an Internet provider or corporate host site compatible
with the V.90 standard or x2 technology are necessary for these high-speed downloads.

Running the Setup Wizard
The instructions for installing your Connections™CD-ROM
software are on the installation map included in your modem’s
box. If you have not completed this portion of your install, you
should do so now.
Using Connections Software
Once installation is complete, you can use the Connections CD
at any time by following these steps:
•Insert the Connections CD into your CD-ROM drive.
•If the CD is already in your drive, take it out and reinsert
it.
•If you have disabled AutoPlay, click Start, point to

The Connections CD contains the RapidComm communications
software. RapidComm is used with standard modems;
RapidComm Voice is used with modems with voice
functionality.
Once you have installed the Connections program group, you
can install the RapidComm software. (The Setup Wizard does
not install RapidComm.)
Follow these instructions to install RapidComm:
