After

signal
is
acquired
and
your
current
position
has
been
determined,
the
GP
‐
102
shows
non
‐
blinking
satellite
icon
with
arcs
;
more
arcs
meaning
better
signal
quality
with
more
satellites
used
for
an
accurate
position
fix.
The
GP
‐
102
is
now
ready
to
be
used.
The
time
it
takes
to
reach
position
fix
from
powering
on,
after
several
hours
of
unused
period,
may
vary
from
30
seconds
to
couple
minutes,
depending
on
the
surrounding
environment.
Places
with
unobstructed
sky
view
will
result
in
faster
position
fix.
If
the
GP
‐
102
had
been
previously
used
within
the
2
hour
period
before
powering
on,
the
time
to
reach
position
fix
will
be
very
short.
