General issues
Screen is blank.
• Ensure power is connected. If powered by an AC adapter, check that adapter
is plugged into a wall socket and the Deskset power jack. If powered by PoE,
ensure that the network switch is providing power through the correct ports.
The DECT headset doesn’t register. “Registration failed” appears on the
screen.
• Deregister the headset from the deskset to which it had been registered.
• Remove and replace the headset in its charger before pressing Register on
the deskset.
Intercom calls (Pages) are not received.
• Your phone can be congured to answer intercom calls (pages)
automatically. See your system administrator if your phone doesn’t answer
intercom calls automatically.
Calls are answered on the headset rather than the speakerphone after I
press a Line key or Answer to answer a call.
• Change the audio mode from Headset to Speaker. See “To set the audio
mode:” on page 60.
Incoming calls do not ring on the deskset when using a cordless handset.
• If you are on a call using the handset, then additional incoming calls will emit
a call waiting tone on the handset, but the deskset ringer will be silent.
My computer can’t connect to the network after plugging the Ethernet cable
through the PC port.
• Make sure the deskset is connected to power. The PC port does not work
when the deskset does not have power source or during a power outage.
• Make sure you plug the Ethernet cable connected to the router into the
deskset Ethernet port and the Ethernet cable connected to the computer into
the deskset PC port.
The network connection speed on my computer drops signicantly after
plugging the Ethernet cable through the PC port.
• If you are using a Gigabit Ethernet system, the connection speed drops to
100 Mbps after plugging the Ethernet cable through the PC port.
