To Access the Wires-X Network on a Yaesu FTM7250DR
First let's set up your radio for Wires-X Network access. On our Repeater system we use DG-ID of "1" to operate Wires-X Network. There are 2 different ways to do this. One way is to set the DG-ID to TX-1 as we showed you to connect to different repeaters together. This radio has a trick built into the software to do that automatically. Follow the menu options to set the radio up to do this automatically.
Hold down the MHZ/SETUP Button for 2 seconds and you will see the SETUP MENU.
Change the DG-ID from "Auto" to "01". Hold down the MHZ/SETUP Button for 2 seconds to exit the Menu.
Select the menu item "56" W--DGID.
Quickly press the "MHZ/SETUP" button and get this display.

Now that your radio is set up to use Wires-X through our repeaters, Let's do it!
Quickly press the "P3" button on the microphone.
See the different display? Just like that, you are in Wires-X mode! See the display? This tells you what room you are in.
If you hold down the microphone "P3" button for 2 seconds you will exit the Wires-X mode. Give it a try, go back and forth.
Now that you are in the Wires-X mode, where do you want to go? Well probably a Wires-X Network Room. There is only one way of doing that let's look at that now:

Rotate the knob on the right of the radio counter clockwise till you get the screen shown in the picture on the left.
Now we touch the microphone number buttons to enter the room number.  You can find the room numbers at:

Let's enter
21636 for the Texas-Nexus room. When done push the "#" button on the microphone.
After a couple of seconds you will see this Screen showing "TEXAS-NEXUS" as the room you are in. When someone talks in the room you will hear it. And when YOU transmit on your radio and talk the people in the room will hear you.
To disconnect from the room push the "
*" button on the microphone for 2 seconds and it will disconnect you. Please disconnect from a room when you are done using it.
There are many more things that we could go on and on about. But at this point I will let you explore what we have done thus far - Have FUN!
