Here is what it says:

The Gragraph is a home seismograph that warns you as an earthquake is
occurring, measures the intensity, and records the data in its
calendar. The verbal warnings are in Japanese, but the digital data
can be easily accessed in any language. In normal mode, the Gragraph
serves as a tabletop calendar/clock and a reference for past activity.

Gragraph features:
=95 Perceives shaking, and indicates on display
=95 Warns of shaking with sound and voice
=95 Indicates level from 3-10
=95 Keeps record of previous seismic activity
=95 During the night, it activates a safety light
=95 Calendar/Clock function
