Help! B–5
Other Problems
The dial tone is not audible through the handset,
though everything else works.
Verify that the handset cord is securely connected to
both the handset and the bottom of the telephone.
The other party cannot hear you when you are
using the speakerphone, though everything else
works.
Verify that your telephone is equipped with a
speakerphone (speaker and microphone). Check the
telephone name on the label underneath the tele-
phone. RP312, RP312L, RP612, RP612L, RP624,
and RP624L do not have microphones, and you must
use the handset to speak to the other party.
The telephone does not ring when called, though
everything else works.
Verify that the telephone is not forwarded. If the tele-
phone is forwarded, the line key flickers. See
“Forwarding” on page 5–3 for information on
forwarding and cancelling forwarding.
Also verify that the telephone is not in Do Not Disturb
mode. To cancel Do Not Disturb, press the Do Not
Disturb (DND) key until its status light turns off.
Your speakerphone turns on and off when the
other party is talking.
Noisy environments may cause the speakerphone to
behave as if you are talking, thereby cutting off the
other party. If you cannot eliminate the background
noise, try using the Mute feature while the other
person is talking, and then de-activate it when you
want to talk to them. (See “Muting the Speakerphone”
on page 2–16.)
