MVP Remo-Con. Pocket Tone Dialer Model PD-911M

Circa Early 1980's to Mid 1990's

Use Case:

This device was used to allow users with an older rotary-dial (pulse-dialing) telephone to make calls that required Dual-Tone Multi-Frequency (DTMF) or "Touch-Tone" signals. This was necessary to interact with automated phone systems, voicemail, or certain long-distance services which did not recognize pulse dialing. The user would dial the initial number with the rotary phone, wait for a dial tone (or connection), hold the tone dialer's speaker up to the phone's microphone (transmitter), and then press the desired keys on the pad to generate the tones needed. It also included memory functions to store up to 10 numbers.

Historical Significance:

This pocket tone dialer is historically significant as a practical and affordable "bridge" technology during the transition from older, electromechanical rotary-dial telephone systems to modern, all-electronic Touch-Tone systems. It provided access to emerging automated services without requiring users to purchase a new, expensive push-button phone. Interestingly, these devices also gained notoriety in pop culture for their use in phone "hacking" (specifically creating "red box" tones for making free long-distance calls from payphones), though their primary purpose was for legitimate communication.
