Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your

purchase, be sure to read this manual carefully and keep it on hand for later reference

when necessary.

Warning!

• The longitude, lunitidal interval, Moon phase indicator, tide graph data, and solar

azimuth data that appear on the display of this watch are not intended for

navigation purposes. Always use proper instruments and resources to obtain data

for navigation purposes.

• This watch is not an instrument for calculating low tide and high tide times. The

tide graph of this watch is intended to provide a reasonable approximation of tidal

movements only.

• When engaging in mountain climbing or other activities in which losing your way

can create a dangerous or life-threatening situation, always be sure to use a

second compass to confirm direction readings.

• CASIO COMPUTER CO., LTD. assumes no responsibility for any loss, or any

claims by third parties that may arise through the use of this watch.

Home Site Data

Tide graph data and Bearing Mode solar azimuth data will not be displayed properly

unless Home Site data (GMT differential, longitude, and lunitidal interval) is configured

correctly.

• The GMT differential is the time difference of the time zone where the site is located

from Greenwich Mean Time.

• Note that you must add one hour to the GMT differential for your time zone

whenever you change to Daylight Saving Time. Subtract one hour when you change

back to Standard Time.

• The lunitidal interval is the time elapsing between the Moon’s transit over a meridian

and the next high tide at that meridian. See “Lunitidal Interval” for more information.

• This watch displays lunitidal intervals in terms of hours and minutes.

• The “Site/Lunitidal Interval Data List” provides GMT differential, longitude, and

lunitidal interval information around the world.

• The following is the initial factory default Home Site data (Tokyo, Japan) when you

first purchase the watch and whenever you have the battery replaced. Change these

settings to match the area where you normally use the watch.

GMT differential (+9.0); Longitude (East 140 degrees); Lunitidal interval (5 hours,

20 minutes)

To configure Home Site data

1.In the Timekeeping Mode, hold down A until the

seconds start to flash, which indicates the setting

screen.

2.Press A again to display the GMT differential setting

Bearing Mode

The Bearing Mode lets you determine approximate

directions using a displayed angle value that indicates the

angle to the sun (solar azimuth).

• All of the operations in this section are performed in the

Bearing Mode, which you can enter from the

Timekeeping Mode by pressing B.

Important!

Before the watch can calculate the solar azimuth (the

angle of the sun in relation to your location) correctly, you

must first set the correct current time, current date, and

Home Site in the Timekeeping Mode. You must also

specify whether the sun traverses the sky to the north or

to the south of your current position.

Solar azimuth

• Note that you cannot use the Bearing Mode to determine directions in the following

cases.

When the sun is not visibl

e

At night

When sun traverses the sky directly overhead or when you cannot determine if it

traverses to the north or south

To set the traverse direction of the sun

1.In the Bearing Mode, hold down A until N or S flashes

on the display. This indicates the setting screen.

2.Press D to toggle the setting between N (north) and S

(south).

3.Press A to exit the setting screen.

• At this time the watch uses the traverse direction setting

you just configured and the Timekeeping Mode data to

calculate and display the solar azimuth.
