Note
•Auto DST (AvtA) can be selected only while LON, PAR, BER, ATH, HKG, TPE, TYO, LAX, DEN, CHI, or NYC is selected as the Home City code. For more information, see “Daylight Saving Time (DST)” below.
•You also need to enter the Timekeeping Mode in order to configure the following settings.
Power saving on/off (“To turn Power Saving on and off”) Temperature, barometric pressure, and altitude units (“To select the temperature, barometric pressure, and altitude units”)
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), Anthorn (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.
•Though the time calibration signal transmitted by the Fukushima and Fukuoka/Saga, Japan transmitters include summer time data, summer time currently is not implemented in Japan (as of 2007).
•The default DST setting is Auto DST (AvtA) whenever you select LON,
PAR, BER, ATH, HKG, TPE, TYO, LAX, DEN, CHI, or NYC 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.

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, Receive, or Barometer/Thermometer Mode.
•If you do not perform any button operation for 21 or 22 hours while in the Altimeter Mode, the watch will return to the Timekeeping Mode automatically.
•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 or Alarm Mode, the data you were viewing when you last exited the mode appears first.
Scrolling
The E and B 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.
Barometric Pressure | Altitude |
Measurement | 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 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 Mute indicator the display), hold down D to toggle the button
operation tone on (MUTE not displayed) and off (MUTE 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 MUTE indicator is displayed in all modes when the button operation tone is turned off.
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”.
