This manual introduces the use of 5193 series watches.
This manual provides step‑by‑step instructions for using the Casio 5193 watch, including how to charge the solar‑powered battery, set the time and date, and configure the residence‑city and world‑time functions. It also describes power‑saving modes and how the watch behaves when battery level is low.
Detailed chapters cover radio‑time calibration, city code tables for 29 supported cities, measurement limits, and a troubleshooting guide for common issues such as incorrect time or stopped hands. This manual is written in Japanese.
