This document describes the features and characteristics of CASIO watches, including the functions to measure direction, barometric pressure, temperature, and altitude. This watch is suitable for hiking, mountain climbing, and other outdoor activities.
This operation guide introduces the Casio 3134 watch, a solar‑powered timepiece equipped with direction, barometric pressure, temperature and altitude sensors. It describes how to use the various modes—Timekeeping, World Time, Compass, Barometer, Thermometer, Altimeter, Stopwatch, Countdown Timer, and Tide/Moon data—plus the radio‑controlled atomic timekeeping feature.
The manual also covers battery care, power‑saving behavior, signal‑reception procedures (auto and manual), digital compass usage, and troubleshooting steps for signal and sensor issues. Detailed instructions are provided for setting the Home City, performing manual receives, and calibrating the compass.
| Sensors | Direction, barometric pressure, temperature, altitude |
|---|---|

Enter Receive mode, position the watch with its 12 o’clock side toward a window, then hold down the receive button for about two seconds until “RC!” appears.
The compass measures magnetic north, which can differ from true north and can be affected by nearby metal objects or magnetic fields.
