Starting
up
the
Instrument
Display
From
the
factory,
the
SPEEDWATCH
is
in
a
low
power
state,
with
the
time
“12:00”
flashing.
Press
any
button
to
enter
normal
mode.
The
SPEEDWATCH
is
now
in
Manual
Mode;
it
will
only
receive
data
from
the
transmitter
when
the
CHRONO
button
is
pressed
and
the
impeller
is
rotating.
The
default
speed
is
KNOTS,
which
can
be
changed
to
mph,
km/h,
or
m/s.
Impeller
The
SPEEDWATCH
impeller
needs
to
be
screwed
on
to
either
the
white
fin
mount,
the
large
black
fin
or
rudder
black
fin
mount.
The
impeller
is
magnetized
and
creates
a
magnetic
pulse
when
rotating.
This
magnetic
pulse
is
received
by
the
transmitter
and
transmitted
to
the
display.
The
display
cannot
sense
the
impeller
directly;
the
transmitter
must
be
on.
