Troubleshooting

• If using an AC wall adapter make

sure the DC jack is properly con-

nected at the rear of the telephone.

• If using inline powering from

a switch or hub, check that the

switch/hub is correctly supplying

power to that particular port (con-

tact your System Administrator)

• If the idle display is not similar to

that shown on Page 4, try reboot-

ing the telephone (See Page 16) or

cycling power and allow the unit

to reboot. Contact your System

Administrator if the display still

shows problems.

No Display or Incorrect Display

No Dial Tone

• Make sure that the handset cord ts

the handset and the jack on the rear

panel correctly.

• Switch between Handset, Head-

set (if connected), and Handsfree

Speakerphone Modes to try to ob-

tain dial tone on these other paths.

• Make sure that the LAN cable is

inserted properly at the rear of the

telephone

No Ringing

• Adjust the ringing level from the

front panel using the volume up/

down keys.

• Place a call to the unit from a

known working telephone. Check

for incoming ring signal.

No Audio on Headset

• Ensure the headset is plugged into

the jack marked Headset on the

rear panel.

• Swap the handset into the headset

jack (or vice-versa) and verify that

audio is now present (if so, the

headset may need replacing).

• Ensure the headset amplier (if

connected) is turned on and/or the

volume is correctly adjusted. If the

amplier is equipped with batteries,

check that they are fully charged.

No Response from Key Presses

• Some keys are inactive when the

telephone is not in a call. Check

for a response from other feature

keys or from the dial pad.

• Place a call to the unit from a

known working telephone. Check

for display updates.

• To check if the telephone is cor-

rectly registered to the server, press

Menu followed by System Status

and Server Status.

• Contact your System Administrator

before attempting to reboot your

telephone, since this may allow

more detailed troubleshooting to

occur before losing any current

status information.
