Illumination Precautions.
Illumination may be hard to see when viewed under direct sunlight.
Illumination turns off automatically whenever an alarm sounds.
Frequent use of illumination runs down the battery.
The watch may emit an audible sound whenever the display is illuminated. This is due to the vibration of the EL panel used for illumination and does not indicate malfunction.

Troubleshooting
Time Setting
■ The current time setting is off by hours.
Your Home City setting may be wrong (page E-14). Check your Home City setting and correct it, if necessary.
■ The current time setting is off by one hour.
You may need to change your Home City’s standard time/daylight saving time (DST) setting. Use the procedure under “To change the current time and date settings” (page E-18) to
change the standard time/daylight saving time (DST) setting.
Sensor modes
■ I can’t change the temperature, barometric pressure, and altitude units.
When TYO (Tokyo) is selected as the Home City, the altitude unit is set automatically to meters (m), the barometric pressure unit to hectopascals (hPa), and the temperature unit to
Celsius (°C). These settings cannot be changed.
■ The battery indicator ( ) appears while a sensor operation is being performed.
The battery indicator appears in the left corner of the digital display whenever there is not enough battery power available to perform a sensor operation in the barometer/Thermometer
Mode or Altimeter Mode. Sensor operation is disabled while the battery indicator is displayed. • Normal operation should return after battery power recovers.
■ “ERR” appears while a sensor operation is in progress.
Subjecting the watch to a 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.
