• Color plotter-printer
• Do
not
rotate
the
pen drum in
the
reverse direction when replacing pens.
•
Be
sure
to
remove
the
pens from
th
e pen drum, replace their caps
to
them
, and store
them
in the case
to
prevent them from drying
out
when
the
printer is
not
to
be used for an extended period
of
time.
•
It
takes a certain
amount
of
time for ink
on
the
paper
to
dry. (The ink
is
water-soluble.)
• Do
not
rip
off
the
paper when the printer cover
is
removed. Hold down
the
paper holder when ripping
off
the
paper.
• Do
not
touch
the
internal mechanism when replacing
the
pens. Failure
to
observe this warning may
result in damage
to
the
printer.
• The calor
plotter
printer generates sound· for a
moment
when
the
power
is
turned on. This
is
not
a problem.
• Letters printed in
the
80
character line mode may be difficult
to
read.
In
this case, use the
40
character/
line mode.
• In
the
graphic mode, lines printed repeatedly may become blurred. This
is
particularly liable
to
occur
when a
dotted
line
is
printed repeatedly. Due
to
the
characteristics
of
the
ball pen, this
is
unavoidable.
• Notes concerning software
•
It
takes
about
3 minutes
to
load the BASIC interpreter.
• The reset switch
on
the
rear panel is
to
used in
the
following cases. (See 3.
1.
1.)
To
stop execution
of
a BASIC program during normal execution
or
when
the
program enters an infinite
loop.
To
return to
the
program, use
the
# command. However, the program
or
hardware should be
checked
if
the
program loops.
• BASIC calculation error
• BASIC converts decimal values
to
floating point binary values before performing calculations,
then
converts
the
binary calculation results
into
decimal numbers for display. This can result in a certain
amount
of
error.
(Example:)
PRINT
817
.
3-81
0
.4
6.
899
9
99
· · · · · · · · · Correct result
is
6.
9.
• Approximations are made during calculation
of
functions and exponentiation.
• The above
must
be considered when using
IF
statements.
(Example:)
1 0 A
=1
/ 1
00
*1
00
2 0
IF
A
=1
THEN
PRINT
"
TRUE
"
3 0
PRINT
" F A
LSE
"
4 0
PRINT
"
A=
"
;A
5 0 END
RUN
FA
LSE
A
=1
:GOTO
40
Although
the
practical result
of
the equation in line 10 is
1,
this program prints FALSE because
of
error due
to
conversion.
