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, Headset, or DHSG Headset" on page 11 for information.

Why is my speakerphone not working?

If you press Headset	and the speaker light flashes and you do not hear dial
Speaker/

tone, the Set Audio option has been used to set up the phone for headset

use; press Headset	a second time. If the light goes out, the phone is set up to
Speaker/

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

Headset

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 9 for details.

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

1.Press the Options 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, Headset, or DHSG Headset" on page 11. 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.
