How to set the time and calendar

  1. Turn the rotating bezel to align “TIME SET” with the mode indicator mark (MODE-2).
    The “day of the week” and “day” will disappear and “seconds” will blink.

  2. Press Button Button B in accordance with a time signal. The seconds are reset to “00”.

  3. If Button Button B is pressed while the seconds digits count any number between 30 and 59, one minute is added and the seconds digits are reset to “00”.

    The telephone time signal service is helpful for setting the seconds hand exactly.

  4. Press Button Button A to proceed through the order shown below and select the desired location (blinking).

    Once the year, month and date are set, the day of the week is set automatically.

  6. After selecting the desired location by pressing Button Button A, each press of Button Button B advances the blinking number by one.

  7. For the 12-hour and 24-hour system setting, each press of Button Button B switches between 12-hour and 24-hour systems.

  8. When “time/calendar adjustment” is completed, turn the rotating bezel and align “TIME” with the mode indicator mark (MODE-2) to return to “time/calendar display.”

The calendar has a fully automatic calendar function. As the day of the week, day, month, and year from 2025 to 2074 have been programmed in the automatic calendar, you do not need to manually adjust odd and even months and leap years during this period.

Switching between 12-hour and 24-hour system settings also switches alarm time and dual time.

 

Turning On/Off of Time Signal/Button Operation Confirmation Sound and Alarm Test

In “time/calendar display,” when Buttons Button A and Button B are pressed at the same time, the time signal/button operation confirmation sound can be set or turned off. When set, the time signal mark (DQ Bell) lights up. Also, at this time, the alarm tone sounds and can be tested.

A824_Date and Time-4

While the hourly time signal/button operation confirmation sound is turned on, the hourly time signal mark (DQ Bell) is displayed in any mode.
