Altitude change display
When you start measurement (step 2 in the procedure below), the first altitude measurement is used as a base. Then, each subsequent measurement is compared with the base, and the difference is shown on the display. Measurements are taken every 2 seconds for the first five minutes. After that, measurement are taken every minute. To use the altitude change display Altitude change 1. Use C to enter the Altimeter Mode. 2. Press D to change to the altitude change display. At Mode indicator this time, the watch also starts to measure the elapsed time. � You can press D to change to the normal Altimeter Mode display (showing the current time). Though the display changes, elapsed time measurement continues internally. To return to the altitude change display, press D again. 3. Press A to stop the measurement and switch to the normal Altimeter Mode display. Elapsed time � Whenever the elapsed time passes the 60-minute mark, (Minutes, Seconds, the display changes automatically from showing min1/10 second) utes, seconds and 1/10 second, to hours, minutes, seconds. � You can perform altitude change measurements for up to 23 hours, 59 minutes, 59 seconds. Whenever the elapsed time passes the 24-hour mark, measurement is stopped automatically and the normal Altimeter Mode display appears. To perform speed measurements 1. Use C to enter the Altimeter Mode. 2. Press D to change to start measurement of elapsed time. 3. Press B to stop the elapsed time measurement (timing continues internally). � At this time, the average ascending and descending speed appears on the display. 4. Press B again to resume timing from the time being kept internally. � You can repeat steps 3 and 4 as many times as you want. Average speed 5. Press A to stop the measurement and switch to the normal Altimeter Mode display. Notes � The watch is not designed to measure speeds when the altitude changes suddenly over a short period of time. � Depending on conditions, the display may show the speed in terms of hours or minutes. Note the following. Speed 0 to ±999 m/hour More than ±999 m/hour Above ±999 m/minute Speed 0 to ±2,999 ft./hour More than ±2,999 ft./hour Above ±2,999 ft./minute Unit Used m/h m/min. ���� Unit Used ft./h ft./min. ����

ALARM FUNCTIONS
Mode indicator

When the Daily Alarm is turned on, an alarm sounds for 20 seconds at the preset time each day. When the Hourly Time Signal is turned on, the watch beeps every hour on the hour. 1. Hold down A until the hour digits start to flash on the display. The hour digits flash because they are selected. At this time the Alarm is automatically switched on. 2. Press C to change the selection in the following sequence.

3. Press D to increase the number or B to decrease it. Holding down either button changes the current number at high speed. � The format (12-hour and 24-hour) of the alarm time matches the format you select for normal timekeeping. � When setting the alarm time using the 12-hour format, take care to set the time correctly as morning or afternoon. 4. After you set the alarm time, press A to return to the Alarm Mode. � If you do not operate any button for a few minutes while a selection is flashing, the flashing stops and the watch goes back to the Alarm Mode automatically.

To stop the alarm
� Press any button to stop the alarm after it starts to sound.

To turn the Daily Alarm and Hourly Time Signal on and off
Press D while in the Alarm Mode to change the status of the Daily Alarm and Hourly Time Signal in the following sequence.

Both OFF

Daily Alarm only

Hourly Time Signal only

Both ON

To test the alarm
Hold down D while in the Alarm Mode to sound the alarm. Note that this operation also changes the Daily Alarm and Hourly Time Signal on/off setting.

STOPWATCH FUNCTIONS
1/100 second Mode indicator

The Stopwatch Mode lets you record elapsed time, split times, and two finishes. The range of the stopwatch is 23 hours, 59 minutes, 59.99 seconds.

Calibrating the altimeter
The altitude measurements produced on this watch may be affected by barometric pressure. Because of this, we suggest that you calibrate the altimeter using information available from a map or other source. Notes � Calibration is performed in the Altimeter Mode, while the normal Altimeter Mode display is shown. Do not try to perform calibration while the altitude change display is shown. � Though you should not try to perform calibration while the altitude change display is shown, you can perform calibration while the altitude change operation is being performed internally, without affecting the operation. To calibrate the altimeter 1. Enter the Altimeter Mode and confirm that the normal Altimeter Mode display (showing the current time) is shown. 2. Hold down A for about two seconds. In about 6 secA onds, the altitude value should start flashing on the display . 3. Each press of D increases the displayed altitude value by 5 m, while pressing B decreases it. Holding down either button changes the value at high speed. � If you have selected feet as your unit of measurement, the above operations change the reading by 20 ft. � You can calibrate the altitude within the range of �4,000 m to 4,000 m (of �13,120 ft. to 13,120 ft.). � Pressing B and D at the same time resets the watch to its factory calibration. 4. After calibrating the altimeter, press A to return to the normal Altimeter Mode display. � If you do not operate any button for a few minutes while the altitude digits are flashing, the flashing stops and the watch returns to the normal Altimeter Mode display.

ERROR WARNING FUNCTION
This watch is designed to automatically stop taking measurements when there is a sensor malfunction, when battery power drops below a certain level, or when temperature drops below �10°C (or 14°F). Sensor malfunction Example: Barometer Mode Low battery or Low temperature Example: Altimeter Mode

Important! � When a sensor malfunction initially occurs, the �ERR.� message flashes and a buzzer sounds for three seconds. � If the sensor is malfunctioning when it comes time for an barometric pressure measurement to be taken, the corresponding point on the barometric pressure graph is left blank. � There may be cases where the �ERR.� or �BATT.� message is cleared once you change modes. In this case, you can continue using the watch normally unless the error warning message reappears. Whenever there is a sensor malfunction, be sure to take the watch to an authorized CASIO distributor or Service Center as soon as possible. If the appearance of the �BATT.� message is caused by extremely low temperature, the message should clear from the display when normal temperature returns. It is recommended, however, that you still have the watch checked by an authorized CASIO distributor or Service Center.
