Overview

1. Function Description
2. Usage Features
3. Maintenance Features

This document outlines the operation and features of the H41* Abbreviated Instruction watch, a solar-powered timepiece designed for precision and ease of use. The watch incorporates radio-controlled timekeeping, manual adjustment capabilities, and a system for checking and correcting its reference position.

Function Description

The H41* watch is primarily a timekeeping device that displays hours, minutes, seconds, and the date. Its core functionality revolves around solar power, meaning it charges when exposed to light, eliminating the need for battery replacements under normal use. A key feature is its radio-controlled timekeeping, which allows the watch to automatically receive time signals from the Japan station daily, ensuring accurate time synchronization.

The watch provides clear indications for its operational status. The "Reception result indication (NO)" signifies that no signal reception has occurred or that the reception failed. The "Reception-in-progress indication (RX)" lights up when the watch is actively attempting to receive a time signal. The "Reception result indication (H/M/L)" provides feedback on the quality of the last successful reception: 'H' for very good, 'M' for good, and 'L' for not-good.

Beyond automatic time synchronization, the watch offers comprehensive manual adjustment capabilities. Users can manually set the time, date, year, and month, providing flexibility for various scenarios, such as travel across time zones or when the watch has been in an environment where signal reception is difficult. The watch also features a "reference position" system, which is the internal alignment of the hands and date indication. This system ensures that the watch's internal mechanism is correctly calibrated, which is crucial for accurate time display.

Usage Features

The H41* watch is designed for intuitive operation, with several features enhancing its usability.

Solar Power and Charging: The watch is solar-powered, requiring exposure to light for charging. Users are advised to expose the dial to light to ensure it is sufficiently charged for optimal performance. This feature contributes to the watch's low maintenance and environmental friendliness.

Component Identification: The watch's components are clearly labeled for easy identification:

• Crown: A multi-functional control element with two distinct pull-out positions (0, 1, and 2) for different adjustment modes.
• Button A (Lower right button): Primarily used for checking signal reception results and initiating manual signal reception.
• Button B (Upper right button): Used for adjusting the hour and date easily, and for checking and correcting the reference position.
• Hour, Minute, and Second hands: Standard time-telling components.
• Date indication: Displays the current date.
• Reception result indications (NO, RX, H/M/L): Visual cues for signal reception status and quality.

Adjusting the Time and Calendar Manually:

• Setting Time and Date:
  1. Pull the crown out to position 2. The second hand will point to 0 seconds.
  2. Rotate the crown to adjust the time and date. Rotating the crown quickly will cause the hands to move continuously; rotating it in either direction will stop the rapid movement. The change in date indication signifies the transition to AM. Users must ensure the correct AM/PM is set.
  3. Push the crown in to position 0 to finalize the setting.
• Setting Year and Month:
  1. Pull the crown out to position 1. The second hand will indicate the currently set year and month.
  2. Rotate the crown to adjust the year and month. The "Month" corresponds to one of 12 zones on the dial, and "Year" corresponds to years since a leap year (0 for leap year, 1, 2, or 3).
  3. Push the crown in to position 0 to finalize the setting.

Checking Signal Reception Result:

1. Push the crown in to position 0.
2. Press and release the lower right button A. The second hand will move to indicate the result of the last reception (H, M, L, or NO).
3. Press and release the lower right button A again to return to current time indication. The watch will also automatically return to current time after about 10 seconds without pressing the button.

Receiving Signal Manually (On-demand Reception): This process takes 2-15 minutes.

1. Push the crown in to position 0.
2. Press and hold the lower right button A for 2 seconds or more. The second hand will point to "RX," indicating signal reception has started. Upon completion, the second hand returns to normal movement. If reception is successful, the time is updated. If reception fails, the time is not corrected, and the previously set time resumes.
3. To cancel reception, press and hold button A for 2 seconds or more.

Adjusting the Hour and Date Easily: This feature is useful for quick adjustments, such as when traveling.

1. Push the crown in to position 0.
2. Press and release the upper right button B. The hour hand will move back and forth to indicate that the hour and date are adjustable. It will return to normal automatically after about 10 seconds if no operation is performed.
3. Rotate the crown to set the hour and date. Rapid rotation allows continuous movement of the hour hand. The date indication changes when AM is reached.
4. Press and release the upper right button B to finish the procedure. It will return to current time automatically after about 10 seconds without pressing the button.

Maintenance Features

The H41* watch incorporates features that aid in maintaining its accuracy and proper functioning over time.

Checking the Reference Position: The reference position is the internal alignment of the watch's hands and date. Checking this ensures the watch's internal calibration is correct.

1. Push the crown in to position 0.
2. Press and hold the upper right button B for 10 seconds or more. The hands and date indication will move to their stored reference positions.
3. Check the reference position:
   • Hour, minute, and second hands should point to 0 hour, 00 minute, and 0 second.
   • Date indication should be midway between "31" and "1". If the reference position is incorrect, it must be corrected.
4. Press and release the upper right button B to finish the procedure. It will return to current time automatically after about 30 seconds.

Correcting the Reference Position: If the reference position is found to be incorrect, follow these steps:

1. Push the crown in to position 0.
2. Press and hold the upper right button B for 10 seconds or more. Release the button as the second hand starts to move. Wait until all hands and the date indication stop.
3. Pull the crown out to position 1.
4. Rotate the crown to adjust the hour hand and date indication. Rapid rotation allows continuous movement. The hour hand and date indication move synchronously.
5. Pull the crown out to position 2.
6. Rotate the crown to adjust the minute and second hands. Rapid rotation allows continuous movement. The minute and second hands move synchronously.
7. Push the crown in to position 0.
8. Press and release the upper right button B to finish the procedure.

After correcting the reference position, it is recommended to adjust the time and calendar manually or by performing a manual signal reception (on-demand reception) to ensure complete accuracy.

The solar-powered nature of the watch means that regular exposure to light is the primary "maintenance" required to keep it running. The radio-controlled feature minimizes the need for manual time adjustments, contributing to its overall low-maintenance design. The detailed instructions for checking and correcting the reference position empower users to ensure the watch's internal mechanisms remain precisely aligned, which is fundamental for accurate timekeeping.
