TI-3100 Pocket Dialer
Description

The backside of the housing covers a loudspeaker compatible with the headset of an old-fashioned phone. By simply choosing one of about 125 named stored in the internal memory the associated number is given on the display. Simply by pressing the yellow DIAL key the Pocket Dialer converts the number digit by digit into the multitone sound used in the multifrequency phones and emits them with the loudspeaker.
