due to 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.
Barometric
Pressure/Temperature
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.
•
Barometer/Thermometer Mode and Altimeter Mode sensor operations are disabled
whenever there is not enough battery power available to perform a sensor operation.
This is true regardless of the current battery level. 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.
