Reactor Graviton 2 Installation guide

Graviton 2 Tide Ana-Dig
Instructions & Warranty

Welcome
REACTOR watches were conceived, designed
and built to withstand the real world of sport
enthusiasts. We are very proud of what we
have accomplished and we are excited to
welcome you to our ever-growing family.
While your REACTOR watch is built for
maximum durability, you should ALWAYS:
1) rinse thoroughly after use in salt water
2) keep crown securely screwed down
IMPORTANT!
Tide watches are not intended to be used for
navigation purposes. Local NOAA tide charts
should be used when absolute accurate tide
information is necessary. The tide data used
in this watch is derived from the best data
available today, but its accuracy may vary by
location, time of year, weather condition, and
settings performed by the user.

Setting Analog Time
Your Graviton watch is tted with a screw-
down crown to improve water resistance. To
set the analog time, unscrew the crown by
turning counter clockwise until the crown
pops away from the case. Pull crown out
gently until it clicks and set the time. Screw
the crown down rmly clockwise to ensure a
good seal. It is a good idea to routinely check
the crown for tightness to ensure the water
tight integrity of the watch.

Setting Digi Time & Date
In normal Time mode, press and hold A to
enter set mode. Push C or D to change the
hour, then push B to change set mode to
minutes, then seconds. Wait until the analog
second hand reaches twelve, then press C
to synchronize the seconds. Press B again to
advance to set year, month and day, using C
and D to change each as needed. Push A to
exit set mode.
Note on daylight savings time: If you live in
an area that uses daylight savings time (DST),
it is CRITICAL to the proper functioning of the
tide system to use the DST indicator on the
watch and NOT set the time ahead one hour
using the set function. Always set the watch
to standard time, then activate or deactivate
DST mode by pushing and holding the C
button while in normal time mode. A DST
indicator will appear under the seconds.

Tide Mode Methodology
Graviton 2 has been programmed with
tide chart accurate information for 275
locations throughout N. America and the
Pacic through 2020. Dierent tide charts
for the same locations will tend to vary a bit
depending on their prediction criteria, but
Graviton should provide you with more than
acceptable accuracy for all programmed
locations.
In addition Graviton provides an oset of ±
180 minutes to allow you to add your specic
location if it is not in the database.
Graviton allows you to store your four favorite
locations into short term memory for quick
access. Location # 1, (HOME) is linked to the
tide info in the normal time mode, showing
the next 2 upcoming tides, heights, sunrise
and set and moon phase. Locations 2, 3 and 4
can be accessed in the tide mode.

Tide Mode - Set Locations
From the time mode, push B to enter tide
mode. HOME will display briey and then
change to the name of your home location.
This beach drives the tide time, sunrise, sunset
and moon phase information that is displayed
in normal time mode (see following pages).
The rst two tides of the day will be displayed.
Press C to view the next two tides. Push and
hold A to enter set mode. The country or U.S.
state of your current home beach will display.

Push C and D to cycle through the states
and countries in memory.When you reach
the desired state or country, push B to enter
BEACH mode, then push C and D again to cycle
through the beaches.When the desired beach
is located, push A to select and exit set mode.
Push D to advance to BEACH 2 and repeat
location setting procedure. Repeat for BEACH 3
and BEACH 4 if desired.
Using the Oset Feature:If the location you
want isn’t programmed into the watch, you
can still get fairly accurate tide info using the
oset feature. Complete the location setting
previously described to choose the closest
locale from the database. After choosing
the location, push B to enter oset mode.
Determine the oset by comparing a paper
tide chart for the desired location to the data
in the watch. If desired tides are later, enter a
positive oset by pressing C. If earlier, enter a
negative oset by pressing D. Push A to select
and exit set mode.

Tide Mode - Future Tides
While in tide mode, you can check tides for a
date other than today for any of the beaches
loaded into one of the four memory positions.
Choose either HOME, or BEACH 2, 3 or 4, then
push and hold button C. The location name
will change to the date. Press C to advance,
and D to go back. Each press changes to the
next (or previous) two tides. Push and hold C
again to return to today.
Confused?
While the Graviton 2 is a very advanced
watch, it does take some time to learn all of
its capabilities. More detailed instructions are
available on our website.
And of course, if you still need a little more
help, our sta is available M-F from 8-5
Pacic to answer any questions. Call us at
800-291-6600.

Tide Graph & Moon Phase
The tide graph displays a quick visual reference
of the current tide state. The arrow indicates a
rising or falling tide, while the graph displays
where the tide is in the HI/LO cycle. In the
example at right, the tide is rising and is half
way from LO to HI tide.
The moon phase display is straightforward.
When all the segments are black, the moon is
full. No black segments, no moon.
