This document is a user manual for Casio watches. The watch does not have a city code for the UTC -3.5-hour time difference and cannot display the time correctly for Newfoundland, Canada. The watch has a radio wave timekeeping function and a rechargeable battery. Before using the watch, the battery level and the settings for the residential city and daylight saving time need to be checked, and then the radio wave timekeeping function can be used.
This manual explains how to operate the Casio 5088MA0910‑ChA solar‑powered watch. It covers initial checks, charging methods, city and daylight‑saving settings, manual time/date adjustment, and the radio‑signal time‑calibration feature.
It also provides detailed troubleshooting steps for low battery, signal reception problems, and pointer misalignment, plus a full specification table and city‑code list for worldwide time zones. This manual is written in Chinese.
