Do you have a question about the Casio EDIFICE ECB-S100D-2A and is the answer not in the manual?

This document describes the operation and features of a CASIO watch, model 5658, which includes various timekeeping, alarm, stopwatch, timer, and connectivity functions.

Function Description

The CASIO 5658 is a multi-functional timepiece designed for everyday use, offering a wide range of features beyond basic timekeeping. It can display the current time (hour, minute, second), day of the week, and date. The watch supports World Time, allowing users to view the current time in 38 time zones around the globe, with automatic updates when connected to a smartphone.

It includes multiple alarm functions: five daily alarms and an hourly time signal. The alarms can be configured to sound at specific times, and the hourly time signal provides a chime every hour on the hour. A stopwatch function is integrated, capable of measuring elapsed time in 1/100-second units for up to 24 hours, with split time and lap time recording capabilities. A countdown timer is also available, allowing users to set a countdown from 1 second up to 60 minutes, with an audible alert when the countdown ends.

A key feature of the 5658 is its smartphone link capability via Bluetooth. By connecting to the "CASIO WATCHES" app, the watch can automatically adjust its time settings (including Home City, World Time, and summer time) and perform hand alignment. The app also facilitates configuring watch settings, such as alarms, timers, and stopwatch data transfer. This connectivity enhances convenience and accuracy.

The watch incorporates a Tough Solar power system, which converts light into energy to power the watch and recharge its battery. This eliminates the need for regular battery replacement. A power saving function is included to conserve energy when the watch is left in darkness for extended periods, stopping hand movement and disabling certain functions.
