3. Maintenance Features

This document outlines the operational procedures for a CASIO digital watch, model 3512, providing a comprehensive guide to its various functions and features. The manual is available in English and can also be accessed online for additional operational information.

Function Description

The watch offers a range of timekeeping and measurement functions, making it a versatile tool for daily use.

• Timekeeping Mode: This is the primary mode for setting and viewing the current time and date. It supports both 12-hour and 24-hour formats and allows for the adjustment of Daylight Saving Time (DST) settings. The watch automatically displays the day of the week based on the set date.
• Stopwatch Mode: The stopwatch is designed for measuring elapsed time, lap times, split times, and even timing first and second place finishes. It has a display range of up to 99 hours, 59 minutes, and 59 seconds. The stopwatch can store up to 60 records of lap or split times in its memory. Measurement operations continue even if you exit the Stopwatch Mode.
• Recall Mode: This mode allows users to recall and delete the stopwatch time records (logs) stored in memory. It can display both lap and split time records, with the newest log appearing first. Users can scroll through log title screens and individual records.
• Timer Mode: The countdown timer can be set for durations ranging from one minute to 24 hours. An alarm sounds when the countdown reaches zero. The timer also features an auto-repeat function, which automatically restarts the countdown from the original set value once it reaches zero. The countdown operation continues even if you exit the Timer Mode.
• Alarm Mode: The watch supports up to three independent multi-function alarms, which can be set with specific hour, minutes, month, and day. One of these alarms (Alarm 1) includes a snooze feature, repeating every five minutes for a total of seven times. Additionally, an Hourly Time Signal can be activated, causing the watch to beep twice every hour on the hour.
• Dual Time Mode: This mode allows users to keep track of time in a different time zone. It can be set to either Standard Time or Daylight Saving Time, and its seconds count is synchronized with the Timekeeping Mode's seconds count.
• Illumination: The watch features an LED (light-emitting diode) to illuminate the display for easy reading in the dark. Users can select between two illumination durations: approximately 1.5 seconds or 3 seconds.

Usage Features

The watch's interface is designed for intuitive navigation and operation.

• Mode Selection: Pressing the 'C' button cycles through the different modes (Timekeeping, Stopwatch, Recall, Timer, Alarm, Dual Time).
• Setting Adjustments: In setting screens, the 'A' button is typically used to enter and exit the setting mode, while the 'B' and 'D' buttons are used to change flashing values or scroll through options.
• Stopwatch Operation:
  • To start and stop the stopwatch, the 'D' button is used.
  • To record lap or split times, the 'A' button is pressed. Lap numbers are automatically incremented, up to a maximum of 99.
  • To clear the stopwatch to all zeros, the 'A' button is used after stopping the measurement.
  • The display dynamically changes to show hours, minutes, and seconds as the elapsed time increases.
• Timer Configuration:
  • The 'D' button starts the countdown.
  • Pressing 'D' again pauses and resumes the countdown.
  • Pressing 'A' after pausing completely stops the countdown and resets it to its starting value.
  • To configure the countdown start time and auto-repeat settings, hold down 'A' in Timer Mode until the hour setting flashes.
• Alarm Setting:
  • Use the 'D' button to scroll through the alarm screens (Alarm 1, 2, 3, and Hourly Time Signal).
  • Hold down 'A' to enter the alarm time setting screen.
  • The 'B' and 'D' buttons adjust hour, minute, month, and day settings.
  • Alarms can be set as daily, date, 1-month, or monthly alarms by adjusting the month and day settings (using '-' for no month/day).
  • The 'A' button toggles alarms on/off and exits setting screens.
  • To test the alarm, hold down 'D' in Alarm Mode.
• Dual Time Setting:
  • Hold down 'A' in Dual Time Mode to enter the setting screen.
  • The 'D' button moves the flashing selection between DST, hour, and minute.
  • The 'B' and 'D' buttons adjust the values.
• Illumination Activation: Pressing the 'B' button in any mode illuminates the display.
• Button Operation Tone: The button operation tone sounds with each button press. It can be toggled on or off by holding down 'D' in any mode (except a setting screen). When off, a mute indicator is displayed.

Maintenance Features

The manual also provides guidance on aspects related to the watch's upkeep and optimal performance.

• Memory Management: The watch's memory can store up to 60 stopwatch records. When memory becomes full, adding a new record automatically deletes the oldest log and all its associated records to make space.
• Auto Return Feature: To prevent unintended settings, if a setting screen with flashing digits is left untouched for two or three minutes, the watch automatically saves any changes made and exits the setting screen. Similarly, if the Recall Mode or Alarm Mode is left inactive for two or three minutes, the watch automatically returns to the Timekeeping Mode.
• Scrolling: The 'B' and 'D' buttons, when held down during scrolling operations in various modes and setting screens, enable high-speed scrolling through data.
• Timekeeping Accuracy: The watch's built-in full automatic calendar accounts for different month lengths and leap years, requiring no date adjustments once initially set, except after battery replacement.
• Illumination Precautions: Illumination may be difficult to see under direct sunlight and turns off automatically when an alarm sounds. Frequent use of illumination can reduce battery life.
• Battery Life: The manual indicates an approximate battery life based on typical usage patterns, such as daily alarm operations and illumination.
