TAXI PHONE

  
This project is a dedicated device. It dials a single phone number when the handset is lifted. There are two different modes of operation.. A slide-switch on the PC board allows the project to operate in automatic or manual mode. If the switch is in `auto dial` mode, a pre-programmed phone number is AUTOMATICALLY dialled when the phone is lifted. If the switch is in `push to dial,` the project dials the number when the phone is lifted and `push to dial` button is pressed. This allows the phone to be used as a normal phone.
