Problem Solutions
No ring • Check that the ring switch is on.
• Check that incoming calls are not
barred – see page 12.
• Check that you don't have too
many phones connected to your
payphone line.
Your Contour 300 Plus has a REN
of 2, check that the total REN of all
your phones doesn’t add up to more
than 4.
Each phone connected to a phone
line uses the signal that comes down
the line. The signal is only strong
enough for a few phones so you
need to make sure you don’t have
too many phones connected to the
line. The REN number is a guide
to how much of the signal your
phone uses.
