When
connecting or
disconnecting
any peripheral,
be
sure
to turn
the HHC
Primary
Unit off first.
Slor.lf you wish
to
attach more
than
one peripheral at
a
time,
you will
need the
1/0
Adaptor,
which
allows
you to connect up
to
six peripherals at one time (full
instructions for use
come
with the
1
/
0
Adaptor).
TV Adaptor
A
TV
Adaptor
connects
your HHC
to
any
TV
set
,
so that you can view
the HHC
output
on
the
larger
screen as
you type and
edit
.
rather than
one line
at
a time on
the
HHC
Display. It also allows the use
of color
graphics.
With appropriate
capsules,
the
TV
interface also can
be used to
display
accounting,
teaching. and other programs, as
well as
to
play
video
games.
Acoustic Modem
An Acoustic Modem connects your HHC to a
telephone
receiver.
With
the
Telecomputing
capsule,
the Modem
converts
your HHC
into
a
"
computer
terminal."
which
allows
you to
connect
with
such
information
networks
as Source
,
Micronet
.
and
Tymnet.
Micro Printer
A Micro Printer
can
print selected files
from
your File System or
the
schedule in
your
Clock/
Controller.
It
also can give you a
"
hard
copy"
of your Calculator
operations.
Indeed,
it
can provide a
permanent
record of
any program performed
by the
HHC.
Programmable
Memory
A
Programmable Memory adds
extra
random
access memory
(RAM),
thus
amplifying the File System storage capacity.
The 1
/0
Key
and
Menu
Any or all of
these
present and future peripherals that are attached to the HHC are
accessed by the 1/0 key (Input/Output key), which calls up the 1/0
Menu
at any
time without disturbing any program
in
progress.
(I/O
Menu is
displayed only on the
LCD
of
the
Primary
Unit,
and
not
on peripherals. e.g. TV Adaptor)
In addition, while you are
in
the I/O
Menu, the
STP/SPD key and the HELP key are
not
functional. The three keys
•
,
•
and
-
cannot
be
used
at
the
same
time.
Also, don'
t try to make selections from the
110
Menu with
a user-definable key
•
.
•
.
or
•
.
The peripheral
selections that
you make with
the 110
key
remain
in
effect
throughout your use of the HHC. If you
turn
a peripheral on while you are
in
the File
System,
for
example,
when
you
press
-
and then enter another
program,
that
same peripheral
will
keep
working
as it did
in
the previous program.
However,
peripherals
all temporarily stop working while you are in the
Pri
mary
Menu.
Thus
if
you need to stop all peripheral activity quickly-for example,
if
a
printer has run out of paper-press
twice.
