Operation Guide 3173 3246
Congratulations upon your selection of this CASIO watch.
Applications
The built-in sensors of this watch measure direction, barometric pressure, temperature and altitude. 
Measured values are then shown on the display. Such features make this watch useful when hiking, 
mountain climbing, or when engaging in other such outdoor activities.
Warning !
 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.
 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.
 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.
About This Manual
 The operational procedures for Modules 3173 and 3246 are identical. All of the illustrations in this 
manual show Module 3173.
 Depending on the model of your watch, display text appears either as dark fi gures on a light 
background, or light fi gures on a dark background. All sample displays in this manual are shown using 
dark fi gures on a light background.
 Button operations are indicated using the letters shown in the illustration.
 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.
Things to check before using the watch
1. Check the battery power level.
Is “H” or “M” displayed for the battery power indicator?
Go to step 2.
Power is low. Charge the watch by placing it in a location 
where it is exposed to light. For details, see “Charging the 
Watch” .
NO
YES
YES
Does any one of the following conditions exist?
 Battery power indicator shows “L” and “LOW” is displayed in the 
upper left corner of the screen.
 “C” is displayed in the lower left corner of the screen.
 The face is blank.
The watch is charged 
sufficiently.
For details about 
charging, see 
“Charging the Watch” .

2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under “To confi gure Home City settings” to confi gure your Home City and daylight 
saving time settings.
Important!
World Time Mode and Sunrise/Sunset Mode data depend on correct Home City, time, and date settings 
in the Timekeeping Mode. Make sure you confi gure these settings correctly.
3. Set the current time.
See “Confi guring Current Time and Date Settings”.
The watch is now ready for use.
Charging the Watch
The face of the watch is a solar cell 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
Whenever you are not wearing the 
watch, leave it in a location where it 
is exposed to light.
 Best charging performance is 
achieved by exposing the watch to 
the strongest light available.
When wearing the watch, make sure 
that its face is not blocked from light 
by the sleeve of your clothing.
 The watch may enter a sleep state 
if its face is blocked by your sleeve 
even only partially.
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.
 On the dashboard of a car parked in direct sunlight
 Too close to an incandescent lamp
 Under direct sunlight
Important!
 Allowing the watch to become very hot can cause its liquid crystal display to black out. The 
appearance of the LCD should become normal again when the watch returns to a lower temperature.
 Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when 
storing it for long periods. This helps to ensure that power does not run down.
 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. Expose the watch to bright light 
whenever possible.

Power Levels
You can get an idea of the watch’s power level by observing the battery power indicator on the display.

(C)
Except for timekeeping and the C (charge) 
indicator, all functions and display

5
All functions disabled.
 The fl ashing LOW indicator at Level 3 (L) tells you that battery power is very low, and that exposure to 
bright light for charging is required as soon as possible.
 At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery 
reaches Level 2 (M) after falling to Level 5, reconfi gure the current time, date, and other settings.
 Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).
 Leaving the watch exposed to direct sunlight or some other very strong light source can cause the 
battery power indicator to show a reading temporarily that is higher than the actual battery level. The 
correct battery level should be indicated after a few minutes.
 All data stored in memory is deleted, and the current time and all other settings return to their initial 
factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.
Power Recovery Mode
 Performing multiple sensor, illumination, or beeper operations during a short period may cause all of 
the battery power indicators (HM, and L) to start fl ashing on the display. This indicates that the watch 
is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and 
sensor operations will be disabled until battery power recovers.
 Battery power will recover in about 15 minutes. At this time, the battery power indicators (HML) will 
stop fl ashing. This indicates that the functions listed above are enabled again.
 If all of the battery power indicators (HML) are fl ashing and the C (charge) indicator also is fl ashing, 
it means the battery level is very low. Expose the watch to bright light as soon as possible.
 Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer/
Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available 
to power it suffi ciently. This is indicated when all of the battery power indicators (HML) are fl ashing.
 Frequent fl ashing of all of the battery power indicators (HML) probably means that remaining battery 
power is low. Leave the watch in bright light to allow it to charge.

Power Saving
When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain 
period in an area where it is dark. The table below shows how watch functions are affected by Power 
Saving.
 There actually are two sleep state levels: “display sleep” and “function sleep”.
Elapsed Time in Dark
Display
Operation
60 to 70 minutes (display sleep)
Blank, with PS fl ashing
Display is off, but all functions are enabled.
6 or 7 days (function sleep)
Blank, with PS not fl ashing
All functions are disabled, but timekeeping is 
maintained.
 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 in the sleep state.
 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, press any button, or angle the watch towards your face for reading.
To turn Power Saving on and off
1. In the Timekeeping Mode, hold down 
E until the currently selected 
city code starts to fl ash. This is the city code setting screen.
 Before the city code starts to fl ash, the message SET Hold
will appear on the display. Keep 
E depressed until SET Hold
disappears and the city code starts to fl ash.
2. Use 
D to display the Power Saving On/Off screen shown nearby.
3. Press 
A to toggle Power Saving on (On) and off (OFF).
4. Press 
E twice to exit the setting screen.
 The Power Saving on indicator (PS) is on the display in all modes 
while Power Saving is turned on.
