Quick Start
To Make Outside Calls
Use any SA or Pool button or any line button labeled with a
phone number to make an outside call. ICOM buttons are
resewed for inside calls.
Only SA buttons need a dial-out code (usually a 9) before
dialing the phone number.
On BIS Phones
1. If the red light next to the line button you want to use is
not on, press the button.
The red light goes on.
2. Lift the handset or press Speaker.
The green light next to the line button goes on.
3. If you are using an SA button, dial the dial-out code.
4. Dial the phone number.
