[Features]
Automatic adjustment using AC power. A simple and compact radio clock transmitter.
This is a radio clock transmitter that maintains time based on the AC signal obtained from household AC100V. This unit operates by adjusting the delay and advance of its internal clock, focusing on the fact that the AC100V power frequency (50Hz/60Hz) is constantly controlled to prevent cumulative errors.
Once the time is set using the app on a web browser, the internal clock is maintained by time adjustments via the AC signal.
This unit is effective in buildings where standard radio waves are difficult to receive, or especially in basements without a network environment, expanding the possibilities for using radio clocks.
The transmission distance to radio clocks is up to 10m.

Notes
Please use the included AC adapter (dedicated AC-AC adapter) with this product. It will not function with a normal AC adapter (DC output).
The automatic synchronization function of this unit depends on the accuracy of the commercial power supply (AC100V).
Regarding the accuracy of the synchronization function by AC power, the power company and Kyohritsu Electronic Industry do not guarantee that this function will operate normally.
The automatic synchronization function of this unit depends on the accuracy of the commercial power supply. Commercial power supplies are always output while adjusting their frequency, so cumulative errors approach 0 in the long term, but there will be an instantaneous deviation from the ideal value when this unit synchronizes the time.
Temporary deviations may occur during periods of special power demand, such as year-end/New Year holidays, Obon, or other unforeseen weather phenomena (heavy snow, extreme heat) or social events (sports championships, hostage situations) that the power company cannot predict.
If you notice a time deviation, please re-adjust the fractional seconds according to the procedure "■ Display and Clearing of Fractional Seconds" in the instruction manual, or reset the time again.
In environments isolated from large-scale power grids, such as remote islands, and in environments where the power frequency is generated independently (e.g., private power generation, AC inverters), the effect of cumulative error reduction through synchronization may not be achieved.
The appearance and specifications are subject to change without notice. Thank you for your understanding.
