Reference

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.

Auto Return Features

The watch returns to the Timekeeping Mode automatically if you do not
perform any button operation for two or three minutes in the Data Recall,
Alarm, Digital Compass, or Barometer/Thermometer Mode.

If you do not perform any button operation while in the Altimeter Mode, the
watch returns to the Timekeeping Mode automatically after nine or 10 hours
(altitude measurement type:

 2’00

) or after one hour (altitude measurement

type:

 0’05

).

If you leave a screen with flashing digits on the display for two or three
minutes without performing any operation, the watch exits the setting
screen automatically.

Initial Screens

When you enter the World Time, Alarm or Digital Compass Mode, the data
you were viewing when you last exited the mode appears first.

Scrolling

The 

A

 and 

C

 buttons are used on the setting screen to scroll through data

on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.

Sensor Malfunction Indicator

Subjecting the watch to strong impact can cause sensor malfunction or
improper contact of internal circuitry. When this happens, 

ERR

 (error) will

appear on the display and sensor operations will be disabled.

Altitude

Measurement

If 

ERR

 appears while a measurement operation is being performed in a

sensor mode, restart the measurement. If 

ERR

 appears on the display

again, it can mean there is something wrong with the sensor.

Even if battery power is at Level 1 or Level 2, the Digital Compass Mode,
Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled
if there is not enough voltage available to power it sufficiently. In this case,

ERR

 will appear on the display. This does not indicate malfunction, and

sensor operation should resume once battery voltage returns to its normal
level.

If 

ERR

 keeps appearing during measurement, it could mean there is a

problem with the applicable sensor.

Whenever you have a sensor malfunction, be sure to take the watch to
your original dealer or nearest authorized CASIO distributor as soon as
possible.

Button Operation Tone

The button operation tone sounds any time you
press one of the watch’s buttons. You can turn the
button operation tone on or off as desired.

Even if you turn off the button operation tone,
the alarm, Hourly Time Signal, and Countdown
Timer Mode alarm all operate normally.

To turn the button operation tone on and off

In any mode (except when a setting screen is on
the display), hold down 

D

 to toggle the button

operation tone on (

 not displayed) and off (

displayed).

Since the 

D

 button is also the mode change button, holding it down to turn

the button operation on or off also causes the watch’s current mode to
change.

The 

 indicator is displayed in all modes when the button operation tone is

turned off.

Mute indicator

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”.

Operation

Display is off, but all functions are
enabled.

All functions are disabled, but
timekeeping is maintained.

Wearing the watch inside the sleeve of clothing can cause it to enter the
sleep state.

The watch will not enter the sleep state while the digital time is between
6:00 AM and 9:59 PM. If the watch is already in the sleep state when the
digital time reaches 6:00 AM, however, it will remain in the sleep state.

The watch will not enter the sleep state while it is in the Digital Compass,
Barometer/Thermometer, Altimeter, Countdown Timer, or Stopwatch Mode.
When the watch is left in any mode besides the Countdown Timer and
Stopwatch Mode, the watch will return to the Timekeeping Mode
automatically after a specific amount of time. Then if left in the dark for the
elapsed time indicated in the table above, the watch will enter the sleep
state.

To recover from the sleep state

Perform any one of the following operations.

Move the watch to a well-lit area. It can take up to two seconds for the
display to turn on.

Press any button.

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 city code starts to flash, which indicates
the setting screen.

2. Press 

D

 nine times until the Power Saving

on/off screen appears.

3. Press 

A

 to toggle Power Saving on (

ON

) and

off (

OFF

).

4. Press 

to exit the setting screen.

The Power Saving on indicator (

PS

) is on the

display in all modes while Power Saving is
turned on.

Timekeeping

Resetting the seconds to 

00

 while the current count is in the range of 30 to

59 causes the minutes to be increased by 1. In the range of 00 to 29, the
seconds are reset to 

00

 without changing the minutes.

With the 12-hour format, the 

P

 (PM) indicator appears on the display for

times in the range of noon to 11:59 p.m. and no indicator appears for times
in the range of midnight to 11:59 a.m.

With the 24-hour format, times are displayed in the range of 0:00 to 23:59,
without any indicator.

The 12-hour/24-hour timekeeping format you select in the Timekeeping
Mode is applied in all modes.

The watch’s built-in full automatic calendar makes allowances for different
month lengths and leap years. Once you set the date, there should be no
reason to change it except when battery power drops to Level 5.

The current time for all city codes in the Timekeeping Mode and World Time
Mode is calculated in accordance with the Greenwich Mean Time (GMT)
differential for each city, based on your Home City time setting.

GMT differential is calculated by this watch based on Universal Time
Coordinated (UTC) data.
