Internal Modems with Speakerphone See your modem's communications software manual for instructions. Making a Speakerphone Call with Communications Software 1 Dial the telephone number using your communications software. 2 To end the call, hang up using your software (see the software's Help file for more information). Answering an Incoming Call External Modems with Speakerphone When you hear your phone ring, press the SPEAKER button. 6 CHAPTER 2: INTERNAL AN D EXTERNAL MODEMS WITH SPEAKERPHONE If you do not hear your phone ring, you may not have the telephone's cord plugged into the modem's PHONE jack. If you are using your communications software to dial speakerphone calls, the software needs to be running in order for you to hear incoming calls. Internal Modems with Speakerphone See your modem's communications software manual for instructions. Speaking Privately to a Caller If you want to talk privately to a caller, you can use a phone handset instead of the speaker by lifting the handset. To use the speaker again, press the SPEAKER button and then hang up the handset. Adjusting Speaker Volume Press the up and down volume buttons on top of the modem (marked VOLUME). Muting a Call External Modems with Speakerphone If you'd like to say something without the receiving party hearing you, you can press the MUTE button. When you mute a call, the ONLINE light will blink. To turn off the mute feature, press MUTE again. (The ONLINE light will stop blinking and remain illuminated for the remainder of the call.) Internal Modems with Speakerphone Refer to your communications software manual for specific speakerphone instructions. 3 UNINSTALLING A U.S. ROBOTICS® MODEM NOTE: These instructions only apply to current U.S. Robotics modems. If the modem you'll be uninstalling was made by another manufacturer, refer to that modem's documentation for instructions. This chapter covers the uninstallation of: I I I I A U.S. Robotics Winmodem® modem. A U.S. Robotics Internal Faxmodem. A U.S. Robotics External Faxmodem. A U.S. Robotics Macintosh Faxmodem. Uninstalling a Winmodem modem (Model Numbers 3CP5699A, 3CPxx5699A, 3CPxx2884A, 3CP5695, and 3CPxx5695) 1 Click Start, point to Settings and then click Control Panel. 2 Double-click the Add/Remove Programs icon. 3 Scroll down, select your modem and click Add/Remove. 4 A reminder that your U.S. Robotics modem will be permanently removed from your system appears. Click Remove to proceed. 5 Click OK to confirm that the modem has been removed from your system. 6 Next, verify that you completely uninstalled the Winmodem software. Click Start, point to Settings and select Control Panel. 7 Double-click the System icon and click the Device Manager tab. If you do not see a modem icon, you've successfully uninstalled your Winmodem software. If you do see an icon, repeat these instructions beginning with Step 1. 8 CHAPTER 3: UNINSTALLING A U.S. ROBOTICS ® MODEM 8 Shut down Windows and turn off your computer. 9 Remove the phone cords from the modem's TELCO and PHONE jacks.
