Components
• Display Contrast Control
When the display
is
dark
or
faint, depending on the battery condition or display
view angle, adjust it by moving the control located on the left side
of
the
computer.
To increase the display contrast, turn the control in the direction indicated by
the arrow. To weaken the contrast, turn it in the opposite direction.
If
the con-
trast
is
still weak even after the control
is
at
its highest-contrast position, the
batteries have probably run down.
If
so, replace the batteries
as
soon
as
possible.
(For battery replacement,
see
page 11.)
• Connector for Peripherals
Use
this connector (I/O port) for connecting
to
optionally available peripherals.
When a printer
is
to
be used, connect on the
FP-
l 2S printer or SB-42 interface
pack (for connecting the computer and
FP-40). When a tape recorder
is
to
be
used, connect
it
with the cassette interface F
A-3
or F
A-5
.
