ADDENDUM
A
To
AH
Those
Using
a
Multi-Line
Key
System:
The Tandy
1200 bps
modem
has a mini
jumper
marked "Wl".
When
this
mini
jumper
is
on,
A/Al
are
active.
A/Al
are
used
to
turn
on
"in
use"
lights
on
many
key
systems.
The
mini
jumper
is
shipped
in
the
"off" position
to
avoid
possible
problems
if
you have two
separate
telephone
lines at
your
home
(or office)
.
The
telephone
company
frequently wires the
second
of
the
two
lines
to
the
same
leads as
A/Al
(pins
2,
5
or
RJ11).
When
the
jumper
is
on,
you
may
experience
problems
with the
second
line
when
using the
modem
on
the
first
line.
