Troubleshooting Solutions

Why is the light not coming on with a new Voice Mail Message?

Your phone system or service provider must provide “Visual” Message

Waiting service for this function to work. Check with your system

administrator for more information.

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

page 16 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 . See the section, "Set Audio" on page 25 for

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 page 14 for details.

Why can I only see 4 options when the installer or user guide says there

are more?

The telephone screen will only show 4 options at a time. To see more, press

the down arrow button .

Can I turn the backlight for the screen on and off?

Yes. You can use the IP phone UI to turn ON and OFF the backlight for the

screen.

1. Press the key.

2. Select Display->Backlight.

3. Press the Change key to turn the backlight on and off.

4. Press Save to save the change.

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 page 16.

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.
