■ Why can’t I change the temperature unit setting?
The temperature unit setting is always Celsius (°C) whenever TOKYO is selected as the Home City. In
this case, the setting cannot be changed.
■Why does “ERR” appear while a sensor operation is in progress?
Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal
circuitry. When this happens, ERR (error) will appear on the upper display and sensor operations will be
disabled.

Measurement
•If ERR appears while a measurement operation is being performed in a sensor mode, restart the
measurement. If ERR appears on the upper display again, it can mean there is something wrong with
the sensor.
•If ERR keeps appearing during measurement, it could mean there is a problem with the applicable
sensor.
World Time Mode
■The time for my World Time City is off in the World Time Mode.
This could be due to incorrect switching between standard time and daylight saving time.
See “To specify standard time or daylight saving time (DST) for a city” (page E-28) for more information.

Battery
■Why is the low battery alert flashing?
Battery power is low. Watch operations are disabled while the low battery
alert is flashing on the upper display.
If the low battery alert disappears after battery power recovers but then
starts to flash again after a short while, it means that you need to have
the watch’s battery replaced.

*As of December 2013, the official UTC offset
for Moscow, Russia (MOW) was changed from
+3 to +4, but this watch still uses an offset of
+3 (the old offset) for MOW. Because of this,
you should leave the summer time setting
turned on (which advances the time by one
hour) for the MOW time.
