Operation Guide 5242

Congratulations upon your selection of this CASIO watch.

Applications

Built-in sensors are used to take direction, barometric pressure, temperature, and altitude readings, which are displayed by the hands of the watch. 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.

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, be sure to leave it in a location where it is exposed to light.

• Best charging performance is

achieved by exposing the watch to light that is as strong as possible.

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

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-15) if its face is blocked by your sleeve even only partially.

E-9

E-10

Important!

• 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.

• 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.

date changing.

All hands stop at 12 o’clock.

• When power drops to Level 3, all functions will be disabled but the watch will continue to keep time

internally for about one week. If you recharge the battery sufﬁ ciently during this period, the hands will move automatically to the correct setting and regular timekeeping will resume. After one week, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults.

Power Recovery Mode

The watch is designed to go into a power recovery mode that temporarily disables functions whenever power suddenly drops below a certain level due to overuse of sensors, illumination, and/or the alarm tone over a short period. All watch operations are disabled 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 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: “second hand sleep” and “function sleep”.

Elapsed Time in Dark Operation

60 to 70 minutes (second hand sleep)

6 or 7 days (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.

• The watch will not enter a sleep state while it is in the Stopwatch Mode.

To recover from the sleep state

Move the watch to a well-lit area, perform any button operation, perform a crown operation (pull-out, rotate), or move your hand to an angle that causes an Auto Light operation.

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-31) 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)

NYC (NEW YORK), CHI (CHICAGO), DEN (DENVER), LAX (LOS ANGELES), ANC (ANCHORAGE), HNL (HONOLULU)

Important!

• The areas covered by

signal transmitters, so certain conditions may cause reception problems.

E-16

• 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)

• As of December 2010, 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 there.

• 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 summer time, etc.

• When using this watch in an area where time calibration signal reception is not possible, you can adjust

the time and date manually.

To get ready for a receive operation

1. Place the watch in a location where signal reception is good.

with 12 o’clock pointed towards a window. Make sure there are no metal objects nearby.

• Signal reception normally is better at night.

• The receive operation takes from three to eight minutes,

but in some cases it can take as long as 16 minutes. Take care that you do not perform any button operation or move the watch during this time.

• Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive”

for details.

• Manual Receive: Perform the operation under “To perform manual receive”.

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. 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. The receive operation

is not performed if a calibration time is reached while you are conﬁ guring settings.

Radio-controlled Atomic Timekeeping Precautions

• Time calibration signal reception is performed automatically while the watch is in the Timekeeping

Mode.

• 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 automatically for the period from 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” (page E-80).

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

– While power is at Level 2 or lower (page E-12) – While the watch is in the power recovery mode (page E-13) – While the watch is in the function sleep state (power saving, page E-15)

Note

Daylight saving time (DST), or summer time as it is known in some countries, calls for setting clocks ahead one hour from standard time during the summer season. Note that the period during which and the areas where Daylight saving time is applied depend on each country. Some countries or geographic areas may not use summer time.
