rapidly for only 5 seconds. Pressing the CO button again gives you an additional 5 seconds.
• This feature overrides "Data Line Security" and "Executive Busy Override Deny."
• When a two-party call is changed to a three-party call and vice versa, a confirmation tone
is sent to all three parties. Eliminating the tone is programmable.
