This is a user manual for a watch, which introduces the watch's usage methods and features.
The Casio 3077 watch manual provides step‑by‑step instructions for all operating modes, including time and date setting, world‑time city selection, alarm configuration, stopwatch measurement, countdown timer setup, and editing of display preferences. Safety notes for lighting and automatic illumination are also included.
Each mode is accessed with the C button and settings are adjusted using the A, B and D buttons. The document details how to enable or disable features such as button‑press sounds, 12/24‑hour format, main‑display styles, 00‑second animation and automatic zoom. This manual is written in Chinese.
