Making Calls

1. Lift the handset or press “hand-free” key, you will hear dialing tone, then you can dial the telephone numbers you want to call.

2. Dialing: dialing the telephone numbers you want to call

3. On completion of dialed digits, you can press “#” to transmit the called telephone numbers. If you don’t dial any key for continual 3 seconds during the dialing, terminal transmits called telephone numbers automatically.

4. During calls, if the telephone numbers is not free ones, the terminal sends out anti-polarity signal.
