This is the operating guide of a Casio watch. The built-in sensors measure direction, barometric pressure, temperature and altitude, and the measured values are displayed on the display. This makes the watch useful for hiking, mountain climbing or other outdoor activities.
This guide introduces the Casio 3043 watch, its built‑in sensors (direction, barometric pressure, temperature, altitude) and solar‑powered battery. It explains how to keep the watch charged by exposing it to bright light and outlines the basic button operations for navigating modes.
Detailed sections cover radio‑controlled atomic timekeeping, selecting a Home City, auto and manual time‑signal reception, digital compass usage, barometer/thermometer functions, and troubleshooting tips for signal reception and sensor calibration.
