Troubleshooting
I cannot page or make
intercom calls.
• If any other of your telephones are having the
same problem, the problem is in the wiring
or local service. Contact your local telephone
company (charges may apply).
• If you are using the speakerphone, eliminate
any background noise. Noise from a television,
radio, or other appliances might cause the
telephone to not dial out properly. If you
cannot eliminate the background noise, first try
muting the telephone before dialing, or dialing
from another room in your home with less
background noise.
• Make sure you dial the extension correctly.
• Make sure Line 1 is connected and has the
same phone number on all system phones.
• The called telephone might be on an external
call. Wait and try again.
• Make sure the Do Not Disturb function is turned
off on the called system telephone (page 15).
• Make sure the [INTERCOM] light is off before
make a page or Intercom call. If the light
is on, the system is busy or the intercom is
unavailable. Try again when the intercom light
goes out.
• Make sure the telephone line cord connected to
line jack L1/L2 was the one provided with the
telephone.
• Check to make sure that each telephone set
has a unique extension number. If the sets
receive AC power at the same time, either at
initial installation or after a power failure, the
extension numbers might be the same. Refer to
the EXTENSION NUMBER section on page 32
of the installation guide.
