3.4.1Front Panel Switches

ORIG	Originate Mode. Desktop version only. Use this pushbutton to manually dial a
	modem or another DataTalker. To use the Originate switch, manually dial the
	remote modem’s number on a phone connected to the voice/fax channel 1 FXS
	connector on your DataTalker. Listen for the dialed modem’s answer tone. When
	you hear it, press and release the Originate switch. Replace the telephone
	handset in its cradle, and your data communications can begin.
101-MDM/TA	DataTalker or Modem/TA Mode. Desktop version only. Place this slide switch in
	the 101 position to use the DataTalker’s standard features. If an internal modem
	or ISDN terminal adapter is installed, place it in the MDM/TA position to use the
	DataTalker as a stand-alone modem or ISDN terminal adapter (e.g., to call a
	BBS or an on-line information service).
RESET	Reset. Rack version only. This is a pushbutton switch located behind a hole on
	the front panel. Use it to reset the DataTalker. (Turn the desktop version off and
	on again to achieve the same result.) Insert a narrow object such as a pen or
	pencil point through the hole to activate it.

3.4.2Power Switch

The power switch on the back panel of the desktop DataTalker provides DC power when placed in the I (on) position, and removes power when in the O (off) position. The rack-mounted DataTalker is hot-swappable, and has no power switch.
