- Most button phones have tone dialing already set. You will recognize them by the fact that when you press the buttons you will hear different tones. On the other hand, when dialing pulse, "dialing" is heard when dialing.
- If the telephone set is not dialing, then after entering the card number, the user will hear the message - "nothing entered - please enter the card number". In this situation, check whether the telephone has been equipped with the tone dialing function.
- To set the dial tone on your camera permanently, move the "Tone - Pulse" (or "T - P") switch to the "Tone" ("T") position. This switch should be located on the handset or the camera housing (back, side, bottom).
