# Manually Dialing Out and conversing through the RTU

Occasionally it is desirable to manually place outgoing calls from the RTU in order to converse with someone by phone line connection.

The following describes how to do this:

1. At the Front Panel, starting in the Normal mode, press the DIALOUT/PRESS TO TALK key, wait until you hear a dial tone, then press the digits of the phone number you want to dial. Each digit you press will be dialed as you press it. You will then hear the sound of the ringing at the other end.
2. When you hear the phone answered, press and hold the same DIALOUT/PRESS TO TALK key as you speak to the person on the line. Release the key to listen. Continue the conversation in this manner. The microphone at the top of the front panel will capture your voice for this purpose.
3. To end the call, press NORMAL. If the DIALOUT/PRESS TO TALK key is not pressed for more than the "Session Time-Out" period, the RTU will automatically end the call and return to Normal mode.
4. If you are at the Front Panel when a phone call is in progress, you may suspend the message report and converse with the person on the other end by pressing the DIALOUT/PRESS TO TALK key as described above. There will be no additional dialing, since connection has already been established. To end the call, press NORMAL.
