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.

• 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.

Warning !

E-1

Important!

• Your watch’s Altimeter Mode calculates relative altitude based on changes in barometric pressure

measurement by its pressure sensor. For more information, see page E-36 and E-48.

• Immediately before embarking or otherwise taking altitude readings, be sure to specify a reference

altitude. If you don’t the readings produced by the watch probably will not be very accurate. For more information, see “To specify a reference altitude value” (page E-44).

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

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.

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

E-10

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

(page E-14) if its face is blocked by your sleeve even only partially.

E-100 Speciﬁ cations

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 (page E-14) 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.

Important!

• If low battery power is indicated, expose the face of the watch to direct light to charge. At Level 5, the

battery is dead, which causes watch functions to stop, all data in watch memory to be deleted, and all watch settings to return to their initial factory defaults.

• The above exposure times all are for reference only. Actual exposure times depend on lighting

conditions.

• For details about the operating time and daily operating conditions, see the “Power Supply” section of

the Speciﬁ cations (page E-103).

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.

• For information about enabling and disabling power saving, see “To turn Power Saving on or off” (page

E-93).

• There actually are two sleep state levels: “display sleep” and “function sleep”.

• 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.

• Power Saving is enabled only when the watch is in the Timekeeping Mode with the Day of the Week

screen displayed (page E-29) or in the World Time Mode (page E-75).

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 (page E-89).

All functions are disabled, but timekeeping is maintained.

Power Recovery Mode

• Performing multiple sensor, illumination, or beeper operations during a short period may cause all of

the battery power indicators (H, M, 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 (H, M, L) will

stop ﬂ ashing. This indicates that the functions listed above are enabled again.

• If all of the battery power indicators (H, M, L) are ﬂ ashing and the

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 (H, M, L) are ﬂ ashing.

• Frequent ﬂ ashing of all of the battery power indicators (H, M, L) probably means that remaining battery

power is low. Leave the watch in bright light to allow it to charge.

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 Date Settings Manually” (page E-33) 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:

LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW Anthorn (England), Mainﬂ ingen (Germany)

below for details.

• Manual rec eive: Perfor m the operat ion under “ To perform ma nual receive” o n page E-19.

Auto Receive

• With auto receive, the watch performs the receive operation each day automatically up to six times (up

to ﬁ ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to the Timekeeping Mode time). When any receive operation is successful, none of the other receive operations for that day are performed.

• When a calibration time is reached, the watch will perform the receive operation only if it is in the

Timekeeping Mode or World Time Mode. The receive operation is not performed if a calibration time is reached while you are conﬁ guring settings.

• Even when the watch is within range of a transmitter, signal reception may be impossible due to the

effects of geographic contours, structures, weather, the time of year, the time of day, radio interference, etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the inﬂ uence of the conditions listed above becomes even greater.

• 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.

Radio-controlled Atomic Timekeeping Precautions

• Strong electrostatic charge can result in the wrong time setting.

• Even if a receive operation is successful, certain conditions can cause the time setting to be off by up

to one second.

• The watch is designed to update the date and day of the week automatically for the period January 1,

2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed starting from January 1, 2100.

• If you are in an area where signal reception is not possible, the watch keeps time with the precision

noted in “Speciﬁ cations”.

• The receive operation is disabled under any of the following conditions.

– While power is at Level 3 (L) or lower (page E-11) – While the watch is in the power recovery mode (page E-13) – While a direction, barometric pressure/temperature, or altitude reading operation is in progress – When the watch is in the function sleep state (“Power Saving”, page E-14) – While the barometric pressure change indicator is displayed – While a countdown timer operation is in progress (page E-79)

• A receive operation is cancelled if an alarm sounds while it is being performed.

• The Home City setting reverts to the initial default of

drops to Level 5 or when you have the rechargeable battery replaced. If this happens, change the

Home City to the setting you want (page E-31) .

During manual receive, the signal level indicator displays the signal level as shown below.

Weak (Unstable) Strong (Stable)

The level indication will change in accordance with reception conditions while reception is being performed. As you watch the indicator, keep the watch in a location that best maintains stable reception.

• Even under optimum reception conditions, it can take about 10

seconds for reception to stabilize.

• Note that weather, the time of day, surroundings, and other factors all

can affect reception.

Using the Altimeter Mode

The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor. It also saves various types of altitude records and data.

Getting Ready

Before actually taking an altitude reading you need to select an altitude screen format and select an altitude reading interval.

Selecting the Altitude Screen Format

You can select either of two screen formats for the Altimeter Mode.

• Altitude tendency graph contents are updated each time you take an altitude reading.

• To take readings of the difference between the altitude at your current location and the altitude at a

reference point, select Screen 2. See “Using an Altitude Differential Value” (page E-42) for more information.

Taking Altitude Readings

Use the procedure below to take basic altitude readings.

• See “Using Reference Altitude Values” (page E-44) for information about how to make altimeter

readings more accurate.

• See “How does the altimeter work?” (page E-48) for information about how the watch measures altitude.
