Troubleshooting
• Do not install this deskset near a microwave oven or on the same electrical
outlet. You might experience decreased performance while the microwave
oven is operating.
• If you plug your telephone in with a modem or a surge protector, plug the
deskset (or modem/surge protector) into a different location. If this does not
solve the problem, relocate your deskset or modem farther apart from one
another, or use a different surge protector.
• Relocate your telephone to a higher location. The telephone might have
better reception in a high area.
• If the other telephones in your building are having the same problem, contact
your telephone service provider.
The deskset display screen is blank.
• Make sure the power cord is connected to both the deskset and an electrical
outlet not controlled by a wall switch.
My calls fade in and out while I'm using my corded handset.
• If you have a corded headset plugged into the telephone, try unplugging it
and firmly plugging it in again.
• If you are using the speakerphone when this problem occurs, eliminate any
background noise. Noise from the television, radio, or other appliances might
cause the speakerphone to cut in and out. Try engaging the MUTE button
when you are not speaking or eliminating the background noise.
My deskset does not ring when I receive a call.
• Make sure that the ringer is not off. Refer to Ringer volume on page 30 in this
user's manual.
• Make sure the telephone line cords, power cord and Ethernet cable are
plugged in securely.
• Make sure the system is properly set up. Refer to Deskset installation on
pages 10-11 for details.
• If the other telephones in your building are having the same problem, contact
your telephone service provider.
• Test a working telephone at the telephone jack. If another telephone has the
same problem, contact your telephone service provider.
• The telephone line cord might be defective. Try installing a new
line cord.
• Make sure that the Line group assignment is correct. See Line group
section on UP416 console's user's manual for more details.
