***Important Notes :
To operate correctly the user must wait between dialed digits to allow the unit enough time to send the translated DTMF Tone. This is best performed by simply listening with the receiver to your ear while dialling. Dial a number, wait for the tone, then continue to the next dial digit. Dialing too rapidly may result in misdialed numbers.
An additional benefit of our pulse to tone converter solutions is that they are telephone line powered devices. In other words they need a small amount of power to operate and they derive this from the telephone line as opposed to having to have an additional wall mounted AC power adapter and cable. Before first use the Pulse to Tone convertor must be plugged into the line for a full 10 minutes to “charge” itself before first usage.
In order avoid any physical strain on the phone and line connectors, we recommend that the unit be placed on a flat surface.
The dial of the connected phone must be fully operational with respect to dialling speed as a faulty dial mechanism could result in misunderstood digits. We provide dial cleaning, lubrication and calibration services for vintage rotary phones that are in need of a tune-up.
Testing has shown that this Pulse to Tone converter will NOT work with Magic Jack nor AT&T Uverse. Some Voice Over Internet Protocol (VOIP) solutions are powered through USB ports on a computer and this simply does not provide enough line power and ringing energy for vintage telephones (with or without the Pulse to Tone converter). The pulse to Tone convertor will work with many VOIP adapters that are specifically designed to power multiple telephone sets or provide a “whole house solution/service”.
