When you edit your MLS Setup or a Phone Book entry, or add a new Phone Book entry, you should specify the phone number of your MLS (or any other remote computer service you are setting up). If you do not, PC Access warns you when you try to close the MLS Setup or Add/Edit Phone Book Entry window. Click the No button if you wish to go back and enter the phone number now. Click the Yes button if you really do want to close the current window without entering the phone number.
If you do not enter the phone number of your MLS, you will have to enter it manually on the Enter Number to Dial... window every time you call the MLS or other remote computer service you are setting up. To reach this window, you must click the Other button on the Calling From window after you click the Call MLS button or the Dial button on the Phone Book window. You must also have checked the Ask for Dialing Location box on the MLS Setup (Dialing Tab) or Add/Edit Phone Book Entry window.
