Timekeeping

To calibrate the pressure sensor and the temperature sensor

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.

Illumination Precautions

1.Press B to enter the Barometer/ Thermometer Mode.

2.In the Barometer/Thermometer Mode, hold down A.

This will cause SET to appear on the display.

3.Release A and wait for four or five more seconds until either OFF or the current reference temperature value (if set) starts to flash. This is the setting screen.

If you want to calibrate the barometric pressure sensor, press C to move the flashing to the upper display area. This is the pressure sensor calibration screen.

At this time, OFF or the barometric pressure value should be flashing on the display.

very long use.

Illumination may be hard to see when viewed under direct sunlight.

Illumination turns off automatically whenever an alarm sounds.

The watch may emit an audible sound whenever the display is illuminated.

This is due to vibration of the EL panel used for illumination and does not

indicate malfunction.

Frequent use of illumination runs down the battery.

Auto light switch precautions

Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can cause frequent activation of the auto light switch and illumination of the display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display.

Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the display and can run down the battery.

Illumination may not turn on if the face of the

parallel. Make sure that the back of your hand

 

 

is parallel to the ground.

 

Illumination turns off in about one second, even

 

if you keep the watch pointed towards your

 

face.

Static electricity or magnetic force can interfere with proper operation of the auto light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards your face again. If this does not work, drop your arm all the way down so it hangs at your side and then bring it back up again.

Under certain conditions, illumination does not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction.

You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch and does not indicate a problem with the watch.

Barometer and Thermometer Precautions

The pressure sensor built into this watch measures changes in air pressure, which you can then apply to your own weather predictions. However, 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 all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

Pressure Sensor and Temperature Sensor Calibration

The pressure sensor and temperature sensor built into the watch are calibrated at the factory and normally require no further adjustment. If you notice serious errors in the temperature readings produced by the watch, you can calibrate the sensor to correct the errors.

Important!

Calibrating the barometric pressure sensor incorrectly can result in incorrect readings. Before performing the calibration procedure, compare the readings produced by the watch with those of another reliable and accurate barometer.

Calibrating the temperature sensor incorrectly can result in incorrect readings. Carefully read the following before doing anything.

Compare the readings produced by the watch with those of another reliable and accurate thermometer.

If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the temperature of the watch time to stabilize.
