The telephone does not
ring when there is an
incoming call.
Appendix J
In case of difficulty
• Make sure the ringer is on (page 14).
• Make sure the telephone line cord(s) and the
power adapter are plugged in properly (see the
installation guide).
• There may be too many extension telephones on
the telephone line to allow all of them to ring
simultaneously. Try unplugging one phone at a
time until the phones start ringing.
• Test a working telephone at the same telephone
jack. If another telephone has the same
problem, the problem is in the telephone jack.
Contact your local telephone company (charges
may apply).

• No spare battery is installed or the spare battery
needs to be replaced.
• Remove and re-install the battery.
• If you are on a conference call with another
telephone in the same system (page 22), the call
cannot be transferred.
• If the destination telephone is on an outside call
or intercom call with another system telephone,
the call cannot be transferred.
• All extensions must have the same outside telephone
line connected to Line 1.
• Make sure the telephone line cord connected
to line jack L1/L2 was provided with the tele-
phone.
• 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 may be the same. Refer to
the EXTENSION NUMBER section on page 32 of
the installation guide.
I cannot transfer outside
calls.
