New Version Pulse to Dual Tone Multi-Frequency DTMF Converter Enhanced Module Features: If your city telephone line does not support dial-up telephones, install this module so you can use any traditional rotary phone on the telephone line normally. It also adds redial and * # functions. DIALOR2.0 converts pulse dialing signals from old telephones into dual tone multi-frequency (DTMF) signals that are compatible with modern telephone switches. This allows vintage or decorative telephones to be used again for regular daily communication. The enhanced version supports redial, * and # functions, enabling older phones to perform like modern ones. Easy to install and use—simply connect two telephone wires to the designated terminal block and plug the telephone line’s crystal head connector into place. Note: When dialing, do not release the dial immediately after rotating; wait until the indicator light turns on. If the light does not illuminate, there may be an issue with the phone. Dialing method follows standard rotary phone operation. Redial method: Dial 1 and hold for approximately one second, then release the dial—this triggers redial. * and # dialing method: Dial 2 and wait about one second before releasing to send the * signal; dial 3 using the same method to send the # signal.
