BAROMETER/THERMOMETER
This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure a temperature.
•You can calibrate the temperature sensor and the pressure sensor if you suspect that readings are incorrect.
Understanding the Barometer/Thermometer Screen
COUNTDOWN TIMER
With the countdown timer, you can set a start time in the range of 1 to 60 minutes, and countdown the time to zero. A beeper sounds each second of the final 10 seconds of a countdown, and you can also turn on a progress beeper that beeps at various times during a countdown. All of this makes the countdown timer a valuable tool for timing the start of a yacht race.
• The countdown timer also can be used as a stopwatch to measure elapsed |
time, split time, and two finishes. See “STOPWATCH” for more |

Press C to enter the Barometer/Thermometer Mode.
•Barometric pressure is displayed in units of 1hPa/mb (or 0.05inHg).
•Temperature is displayed in units of 0.1°C (or 0.2°F).
•The displayed barometric pressure value changes to xxxx hPa/mb (or inHg) if a measured barometric pressure falls outside the range of 260hPa/mb to 1100hPa/mb (7.65inHg to 32.45inHg). The barometric pressure value will be displayed again as soon as the measured barometric pressure is within the allowable range.

Configuring the Countdown Timer
You need to make the settings listed below before actually using the Countdown Timer for timing.

•Auto repeat/repeat, progress beeper on/off
•Graphic on/off
Reset time
You can set a “reset time,” which is a kind of alternate countdown start time
•The displayed temperature value changes to xx. x °C (or °F) if a measured temperature falls outside the range of

Barometric Pressure Graph
Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. The barometric pressure graph shows the barometric readings for the past 26 hours. The flashing point on the right of the display is the point for the newest measurement. Note that pressure graph readings are relative to the newest measurement point. One dot above the newest point is plus 1hPa(mb)/ 0.05inHg, while one dot below is minus 1hPa(mb)/0.05inHg. The following shows how to interpret the data that appears on the barometric pressure graph.
A rising graph generally means improving weather.
A falling graph generally means deteriorating weather.
Note that if there are sudden changes in weather or temperature, the graph line of past measurements may run off the top or bottom of the display. The entire graph will become visible once barometric conditions stabilize.
The following conditions cause the barometric pressure measurement to be skipped, with the corresponding point on the barometric pressure graph being left blank.
•Barometric reading that is out of range (260hPa/mb to 1100hPa/mb or 7.65inHg to 32.45inHg)
•Sensor malfunction
•Dead batteries
you can recall with the press of a button any time a countdown operation is in progress. After recalling the reset time, you can press E to restart the countdown operation from the recalled reset time.
Auto Repeat and Repeat
The countdown timer gives you a choice of two different repeat modes: auto repeat and repeat.
Auto Repeat
When auto repeat is turned on, the countdown automatically restarts from the countdown start time whenever it reaches zero.
Note
•Even if you start a countdown operation from the reset time, the countdown automatically restarts from the countdown start time whenever it reaches zero.
•Auto repeat timing repeats 100 times or until you press E to stop the countdown.
•Auto repeat timing is best when timing the starts of match races.
Repeat Timing
When repeat timing is turned on, the watch automatically switches to the Stopwatch Mode and starts stopwatch timing when the end of the countdown is reached.

Repeat timing is best when timing the speed of yachts during ocean races.

About Barometric and Temperature Measurements
•Barometric pressure and temperature measurement operations are performed as soon as you enter the Barometer/Thermometer Mode. After that, temperature measurements are taken every five seconds for the first three minutes, and then taken every five minutes thereafter.
•The BARO indicator flashes on the display while a measurement is in progress.
•The barometer automatically takes measurements every two hours (starting from midnight), regardless of what mode you are in. The results of these measurements are used for the barometric pressure graph.
•You can also perform a barometric pressure and temperature measurement at any time by pressing C in the Barometer/Thermometer Mode.

Timekeeping 
Mode time
1.While in the Countdown Timer/Stopwatch Mode, hold down A until the time setting starts to flash, which indicates the setting screen.
•This causes the 
indicator to appear on the display.
2.While the countdown start time setting is flashing, use E (+) and B
•You must set a countdown start time in the range of 1'00" to 60'00".
3.Press D to display the reset time setting screen.
•The indicator in the upper display area
changes from 
to 
to indicate the reset time setting screen.
•The pressure sensor built into this watch measures changes in air pressure, which you can then apply to your own weather predictions. It is not intended for use as a precision instrument in official weather prediction or reporting applications.
•Sudden temperature changes can affect pressure sensor readings.
•Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe off all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.
•You can change the measured barometric pressure unit between hecto- pascals/millibars (hPa/mb) and inchesHg (inHg). See “Changing the Barometric Pressure and Temperature Units” for details.
•You can change the measured temperature value displayed by this watch between Celsius (°C) and Fahrenheit (°F). See “Changing the Barometric Pressure and Temperature Units”.
4.While the reset time is flashing, use E (+) and B
minute increments.
• You can set a reset time in the range of 1'00" to 5'00".
5.After making the setting you want, press A to exit the setting screen.
Important!
The reset time setting must be less than the countdown start time setting.
