Applications
This watch has built-in sensors that measure direction.
Measurement results are indicated by the watch’s hands and displays. This feature makes this watch
useful when hiking, mountain climbing, or when engaging in other such outdoor activities.
x The measurement functions built into this watch are not intended for taking measurements that
require professional or industrial precision. Values produced by this watch should be considered as
reasonable representations only.
x When engaging in mountain climbing or other activities in which losing your way can create a
dangerous or life-threatening situation, always use a second compass to confi rm direction readings.
x Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered
by you or any third party arising through the use of this product or its malfunction.
Important!
x Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or
other activities, always be sure to take along another compass to confi rm readings. If the readings
produced by the digital compass of this watch are different from those of the other compass, perform
bidirectional calibration of the digital compass to ensure more accurate readings.
x Direction readings and digital compass calibration will not be possible if the watch is in the vicinity of
a permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or
electrical household appliances (TV, computer, cellphone, etc.)
Warning!
Congratulations upon your selection of this CASIO watch.
x Note that the product illustrations in this manual are intended for reference only, and so the actual product
may appear somewhat different than depicted by an illustration.
This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of
this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland,
Canada.

Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Charging Guide
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot. Take care when
handling the watch to avoid burn injury. The watch can become particularly hot when exposed to
the following conditions for long periods.
x On the dashboard of a car parked in direct sunlight
x Too close to an incandescent lamp
x Under direct sunlight
Whenever you are not wearing
the watch, be sure to leave it in
a location where it is exposed
to light.
x Best charging performance
is achieved by exposing
the watch to light that is as
strong as possible.
When wearing the watch,
makes sure that its face is
not blocked from light by the
sleeve of your clothing.
x The watch may enter a sleep
state (page E-15) if its face is
blocked by your sleeve even
only partially.
E-9
E-10
Important!
x Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps
to ensure that power does not run down.
x Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to
bright light whenever possible.
Checking the Current Power Level
Certain functions will be disabled when the power level is low. If the power level is low, leave the watch in
a location where its face (solar panel) is exposed to light.

x When power drops to Level 3, all settings (including timekeeping) will be cleared. Recharging the
battery will reset all settings to their initial factory defaults.
x When the watch is at Level 3, exposing it to light for a while will cause the 22 Second Hand to move to
the position of second 57. This indicates that charging has started.
Power Recovery Mode
The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever
power suddenly drops below a certain level due to continuous signal reception or other operations over a
short period. Note that all operations are disabled while the watch is in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal operation after power
recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power
to recover sooner.
Power Saving
Power Saving enters a sleep state (second hand sleep or function sleep) whenever the watch is left for a
certain period in an area where it is dark.
Elapsed Time in Dark Operation
60 to 70 minutes (second hand sleep)
6 or 7 days (function sleep)
x The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep
state when 6:00 AM arrives, however, it will remain there.
x The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.
To recover from the sleep state
Move the watch to a well-lit area or press any button.

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. However, when
using the watch outside of areas covered by time calibration signals, you will have to adjust the settings
manually as required. See “Confi guring Current Time and Day Settings Manually” (page E-30) for more
information.
This section explains how the watch updates its time settings when the city code selected as the Home
City is in Japan, North America, Europe, or China, and is one that supports time calibration signal
reception.
If your Home City Code setting is this:
LON (LONDON), PAR (PARIS), ATH (ATHENS) Anthorn (England), Mainfl ingen (Germany)
HKG (HONG KONG) Shangqiu City (China)
TYO (TOKYO) Fukushima (Japan), Fukuoka/Saga (Japan)
HNL (HONOLULU), ANC (ANCHORAGE),
LAX (LOS ANGELES), DEN (DENVER),
CHI (CHICAGO), NYC (NEW YORK)
Important!
x The areas covered by HNL (HONOLULU) and ANC (ANCHORAGE) are quite far from the calibration
signal transmitters, so certain conditions may cause reception problems.
E-16
x Signal reception may not be possible at the distances noted below during certain times of the year or
day. Radio interference may also cause problems with reception.
− Mainfl ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
− Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
− Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
− Shangqiu (China) transmitter: 500 kilometers (310 miles)
x As of June 2014, China does not use Daylight Saving Time (DST). If China does go to the Daylight
Saving Time system in the future, some functions of this watch may no longer operate correctly.
x Using this watch in a country covered by a time calibration signal that is different from the countries it
supports may result in incorrect time indication due to local application of daylight saving time (summer
time), etc.
To get ready for a receive operation
1. Confi rm that the watch is in the Timekeeping Mode. If it isn’t, hold down B for at least two seconds to
enter the Timekeeping Mode.
2. Place the watch in a location where signal reception is good.

or
E-18
The watch can receive the signal from the transmitter
located here:
Fort Collins, Colorado (United States)
x Position the watch as shown in the nearby illustration,
with 12 o’clock pointed towards a window. Make sure
there are no metal objects nearby.
x Signal reception normally is better at night.
x The receive operation takes from two to 10 minutes, but
in some cases it can take as long as 20 minutes. Take
care that you do not perform any button operation or
move the watch during this time.
