The HFL allows you to send numbers or names during a call. This is useful when you call a menu-driven phone system. You can also program account numbers into the HFL phone book for easy retrieval during menu-driven calls.
To send a number during a call, do this:
1. Press and release the Talk Button. After the beep, say "Send." The HFL response is, "What name or number would you like to send?"
2. Press and release the Talk Button. After the beep, say the number you want to send. For example, say "1,2,3." The HFL response is "1,2,3. Say send, or continue to add numbers."
3. Press and release the Talk Button. After the beep, say "Send." The dial tones will be sent, and the call will continue.
The same procedure can be used for names you have stored in your phone book. If you have an account number stored, you can simply say: "Account Number."
