Note
•
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 year can be set in the range of 2000 to 2099. The day of the week is
calculated automatically in accordance with the date you set.
•
The watch’s built-in full automatic calendar makes allowances for different
month lengths and leap years automatically. Once you set the date, there
should be no reason to change it except when battery power drops to Level
5.
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour
from Standard Time. Remember that not all countries or even local areas use
Daylight Saving Time.
The time calibration signals transmitted from Mainflingen (Germany), Rugby
(England), or Fort Collins (the United States) include both Standard Time and
DST data. When the Auto DST setting is turned on, the watch switches
between Standard Time and DST (summer time) automatically in accordance
with the signals.

The time calibration signals transmitted from Fukushima and Fukuoka/Saga
(Japan) do not include summer time data.

The default DST setting is Auto DST (

,
BER
,

as your Home City code.
•
If you experience problems receiving the time calibration signal in your
area, it probably is best to switch between Standard Time and Daylight
Saving Time (summer time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down
E
until the city code starts to flash,
which indicates the setting screen.
2. Press
D
and the DST setting screen appears.
3. Use
C
to cycle through the DST settings in the sequence shown below.
4. When the setting you want is selected, press
E
to exit the setting screen.
•
The DST indicator appears to indicate that Daylight Saving Time is turned
on.
•
If you change your Home City to one that is within the same transmitter
area, the current DST setting will be retained. If you change to a city that is
outside your current transmitter area, DST will be turned off automatically.

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 will return to the Timekeeping Mode automatically if you leave it
in the Depth Data Recall, Alarm, Receive, Digital Compass, or Barometer/
Thermometer Mode for about two or three minutes without performing any
button operation.
•
The watch returns to the Timekeeping Mode automatically if a depth
measurement operation (indicated by ongoing elapsed time measurement
in the upper part of the display) in the Depth Gauge Mode continues for
more than three hours. If there is no depth measurement operation being
performed (indicated by
or
0
in the center part of the display and no
ongoing elapsed time measurement in the upper part of the display), the
watch returns to the Timekeeping Mode automatically if you do not perform
any button operation for about one hour in the Depth Gauge Mode.
•
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.
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).
Mute indicator
•
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.
•
You cannot turn button operation tones on or off while a depth
measurement operation is in progress (at depths greater than one meter).
•
The
indicator is displayed in all modes when the button operation tone is
turned off.
Scrolling
The
C
and
A
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 its sensor to malfunction or
improper contact of internal circuitry. When this happens, the message
ERR
will appear on the display and sensor operations will be disabled.
•
If
ERR
appears during digital compass or barometric pressure
measurement, it will disappear from the display as soon as measurement is
successful again.
•
During depth measurement, elapsed dive time measurement continues
even if
ERR
is on the display. After you surface from your dive, hold down
D
for about three seconds to exit the Depth Gauge Mode. The
ERR
message should no longer be on the display when you re-enter the Depth
Gauge Mode.

Measurement
•
If
ERR
appears during Depth Gauge digital compass measurement, wait
five or six seconds (or press
A
) to return to the depth measurement
screen. This should clear the
ERR
message from the display.
•
If the
ERR
message 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.
