Why is my handset not working?
Check to ensure that the handset cord is fully connected to both the phone
and handset. See the section "Connecting a Handset or Headset"
on
for information.
Why is my speakerphone not working?
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
a second time. If the light goes out, the phone is set up to
be used only with a headset or handset. If the light stays on steady and you
hear dial tone, you can alternate between the speakerphone and the
headset by pressing
instructions on how to change the Set Audio feature.
Why is my display blank?
Ensure that power is being provided to your phone. If your Network does
not provide Inline power over Ethernet, you can obtain an additional
accessory, the a PoE inline power injector, to provide power over
Ethernet locally to your phone. See the section "Connecting to the
Network and to Power" on
for details.

there are more?
The telephone screen will only show 4 options at a time. To see more, press
the down arrow button

backlight for the screen.

Why does the telephone wobble?
Make sure the cords are routed properly through the back of the phone, as
indicated in the section, "Connecting a Handset or Headset" on
Check that the leg stands have been properly snapped into place. Since
the legs can be oriented 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.
