Casio MO0710-EA Manual De Usuario

This watch is equipped with a solar cell and a special rechargeable battery
(secondary battery) that is charged by the electrical power produced by the
solar cell. The illustration shown below shows how you should position the
watch for charging.

Example: Orient the watch so its face is

pointing at a light source.

• The illustration shows how to position a

watch with a resin band.

• Note that charging efficiency drops when

any part of the solar cell is blocked by
clothing, etc.

• You should try to keep the watch outside

of your sleeve as much as possible. Even
if the face of the watch is blocked from
light only partially, charging will be
reduced significantly.

Solar cell

• 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
rechargeable battery power to run down. Make sure that the watch is
exposed to bright light whenever possible.

• This watch uses a special rechargeable battery to store power produced by

the solar cell, so regular battery replacement is not required. However, after
very long use, the rechargeable battery may lose its ability to achieve a full
charge. If you experience problems getting the special rechargeable battery
to charge fully, contact your dealer or CASIO distributor about having it
replaced.

• The special rechargeable (secondary) battery used by your watch is not

intended to be removed or replaced by you. Use of a rechargeable battery
other than the special one specified for this watch can damage the watch.

• The current time and all other settings return to their initial factory defaults

whenever battery power drops to Level 3 and when you have the battery
replaced.

• Keep the watch in an area normally exposed to bright light when storing it

for long periods. This helps to keep the rechargeable battery from going
dead.

The movement of the analog hands indicates the current battery power level.

• When battery power is at Level 2, time calibration signal reception is

disabled.

• At Level 3, all functions are disabled and settings return to their initial

factory defaults. Functions are enabled once again after the rechargeable
battery is charged, but you need to set the time and date, after the battery
reaches Level 1 from Level 3.

Certain charging conditions can cause the watch to become very hot. Avoid
leaving the watch in the areas described below whenever charging its
rechargeable battery.

• On the dashboard of a car parked in direct sunlight

• Too close to an incandescent lamp

• Under direct sunlight

After a full charge, timekeeping remains enabled for up to about four months.

• The following table shows the amount of time the watch needs to be

exposed to light each day in order to generate enough power for normal
daily operations.

• Since these are the specs, we can include all the technical details.

• Watch is not exposed to light

• Internal timekeeping

• Analog hands operational 18 hours per day, sleep state 6 hours per day

• 6 minutes of signal reception per day

• Stable operation is promoted by frequent charging.

This section contains more detailed and technical information about watch
operation. It also contains important precautions and notes about the various
features and functions of this watch.

• If you leave the watch in the Home Position Adjustment Mode for two or

three minutes without performing any operation, it returns to the
Timekeeping Mode automatically.

• If you do not perform any operation for about two or three minutes while a

setting mode is selected, the watch will exit the setting mode automatically.

• The C button is used to change the hand setting in various setting modes.

In most cases, holding down this button will start high-speed movement of
the applicable hand(s).

• High-speed movement of hands will continue until you press any button, or

until the moving hand(s) finishes one complete cycle. One complete cycle
for the hands is 24 hours.

• The watch will not respond to button operations while high-speed hand

movement is being performed. You will be able to perform button operations
again after high-speed operation is stopped.

• High-speed hand movement also is triggered by changing from one mode

to another.

• Strong electrostatic charge can result in the wrong time being set.

• The time calibration signal bounces off the ionosphere. Because of this,

such factors as changes in the reflectivity of the ionosphere, as well as
movement of the ionosphere to higher altitudes due to seasonal
atmospheric changes or the time of day may change the reception range of
the signal and make reception temporarily impossible.

• Even if the time calibration signal is received properly, certain conditions

can cause the time setting to be off by up to one second.

• The current time setting in accordance with the time calibration signal takes

priority over any time settings you make manually.

• The watch is designed to update the date and day of the week automatically

for the period January 1, 2001 to December 31, 2099. Setting of the date by
the time calibration signal cannot be performed starting from January 1,
2100.

• This watch can receive signals that differentiate between leap years and

non-leap years.

• Though this watch is designed to receive both time data (hour, minutes,

seconds) and date data (year, month, day), certain signal conditions can
limit reception to time data only.

• If you are in an area where proper time calibration signal reception is

impossible, the watch keeps time within 

±20 seconds a month at normal

temperature.
