NOTES ON ULTRASONIC ALARM
● The alarm can be set on a 12-hour basis.
● When using the ultrasonic alarm, make sure that the watch bracelet fits snugly on your wrist so that
the vibration of the watch can be perceived clearly.
● Please note that, while you are engaged in an active sport or work requiring arm movement, the
vibration of the watch may not be perceived clearly.
● The alarm time scale may be graduated differently depending on the model. When reading the current
time, take care not to mistake the alarm time scale for the current time scale.
BATTERY LIFE INDICATOR
When the battery nears its end, the second hand moves at two-second intervals instead of normal one-
second intervals to indicate that the battery needs to be replaced with a new one.
BATTERY CHANGE
The miniature battery which powers your watch should last approximately
2 years. However, because the battery is inserted at the factory to check
2
Years
the function and performance of the watch, its actual life once in your
possession may be less than the specified period. When the battery expires,
be sure to replace it as soon as possible to prevent any malfunction. For
battery replacement, we recommend that you contact an AUTHORIZED
SEIKO DEALER and request SEIKO SR43W battery.
* The battery life may be less than 2 years if the ultrasonic alarm is used more
than 10 seconds a day.
* When the battery nears its end, the ultrasonic motor runs slowly. In that case,
replace the battery with a new one. (The time accuracy is not affected)
