with your system administrator for more information.

If you press and the speaker light flashes and you do not hear dial tone, the Set Audio option has been used to set
up the phone for headset use; press
headset or handset. If the light stays on steady and you hear dial tone, you can alternate between the speakerphone and

Why is my display blank?

Why does the telephone wobble?
Make sure the cords are routed properly through the back of the phone, as indicated in the section,
set or Headset" on page 10. Check that the leg stands have been properly snapped into place. Since the legs can be ori-
ented in two different ways and in two different positions to offer four different phone viewing angles, check that both
legs are oriented in the same direction and in the same position on either side of the phone.
What is a softkey?
The 6757i has 12 softkeys (6 on the top and 6 on the bottom). You can program all 12 softkeys to perform specific
functions on the phone. These keys are located at the center of the phone on either side of the display panel. Refer
