Troubleshooting
I hear a double-beep sound every 30 seconds.
• There is a call on hold at this extension. Press the LINE key of the call on
hold to return to the call and turn off the reminder beep.
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.
• Make sure the backup battery is installed and is charged.
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 18 in this
user's manual.
• Make sure the power cord or the backup battery is plugged in securely.
• Make sure the system is properly set up. Refer to Deskset installation on
pages 4-5 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 cords connecting to the console might be defective. Try
installing new line cords.
• Make sure that the Ring group assignment is correct. Refer to Deskset
information for the ring group status of the deskset. To change the setting or
for more details, refer to Ring group section in user's manual of CM18445/
AM18447 console.
My caller ID isn't working.
• Caller ID is a subscription service. You must subscribe to this service
from your telephone service provider for this feature to work on your deskset.
• The caller must be calling from an area that supports caller ID.
• Both your and your caller's telephone service providers must use caller ID
compatible equipment.
