NOTE: The term "base" above refers to the telephone base, not the charger provided with expansion handsets.
• You may be out of range. Move the handset closer to the base.
• Appliances plugged into the same circuit as the base can cause
interference. Try moving the appliance or base to another outlet.
• The layout of your home or office might be limiting the operating range.
Try moving the base to another location, preferably on an upper floor.
• If the buttons don't work, try placing the handset in the base for at least
15 seconds.
• Disconnect the base from the modular jack and plug in a corded tele-
phone. If calls are still not clear, the problem is probably in your wiring or
local service. Call your local telephone service company.
• If only Internet calls do not ring, make sure your computer is on,
connected to the Internet, and all required software is running.
• Make sure the ringer for the non-ringing line is on (see page 15).
• Make sure the telephone line cord and AC adapter are plugged in prop-
erly (see page 5).
• Move the handset closer to the base.
• You might have too many extension phones on your telephone line to
allow all of them to ring. Try unplugging some of them.
• If the error message "Not Registered" is displayed, return the handset to
the base. If the error message remains after 60 seconds, you will have to
manually re-register the handset (see next page).
• Intercom and call transfer features cannot be used when both Internet
and standard telephone lines are in use. Try again when one line is free.
• The telephone's date and time are taken from your PC. Make sure your
PC is set to the correct time and date.
