This is a manual for CASIO watches. The watch has six global time synchronization functions: Japan JJY, USA WWVB, UK MSF, Germany DCF77, China Hong Kong HKG and China Taipei TPY. It can set time and date, including summer time setting.
This manual describes how to charge the Casio 4749 watch. The device uses a solar‑powered battery that should be placed in bright light or sunlight for charging, and it can also be charged in well‑lit indoor areas. When the battery level is low, the second hand jumps every two seconds and the watch may enter a sleep mode to conserve power.
The guide also covers the watch’s features such as automatic time‑signal reception, tide‑display mode, world‑time function, city‑code selection, and how to switch between these functions using the button. Additional sections explain the operation of the solar panel, the handling of low‑battery warnings, and maintenance tips. This manual is written in Chinese.
Place the watch in bright light or sunlight; it can also be charged under bright indoor lighting.
Press the button to cycle through functions; each press changes to the next function.
Place the watch in a bright area to recharge or press the button to wake it up.
