remarks

■The automatic synchronization function of this unit depends on the accuracy of the commercial power supply. Since the commercial power supply always adjusts the frequency while outputting, the accumulated error approaches 0 in the long run. occurs.
■In the event of special power demand, year-end, New Year's holidays, Obon, or other weather phenomena (heavy snow or abnormally high temperatures) that electric power companies could not predict, or social phenomena (sports championships, barricaded incidents, etc.), temporarily Madness can occur. If you feel that the time is out of order, please readjust the fractional seconds according to the procedure in the instruction manual "Displaying and clearing fractional seconds" or set the time again.
■ In environments such as remote islands that are separated from large-scale power distribution networks, or in environments that generate their own power frequency such as in-house power generators or AC inverters, the synchronization function may not be effective in preventing cumulative errors. I have.

A time transmitter that can accurately operate a radio clock even in a basement

Notes

Precautions This unit synchronizes with the AC100V power supply frequency and operates while adjusting the delay and advance of the internal clock, so it can be used in environments such as remote islands that are isolated from large-scale power distribution networks, or in environments where private power generation or AC inverters are used. In a frequency generating environment, the ability to adjust for errors due to synchronization of AC power is not available. Therefore, in this case, automatic recovery will not be performed if there is an error of several seconds per year.

Relation

Radio-controlled clock Radio-controlled clock radio wave transmission Poor radio wave reception Radio wave interruption Building Basement Warehouse No internet environment Radio wave amplification Radio wave enhancement

For those who

・Poor reception of radio waves in a building ・Cannot receive radio waves underground ・Want to use radio-controlled clocks in places where there is no internet environment

from the person in charge

If the radio wave environment is poor in an apartment, you may not be able to use the radio clock in any room, but if you have this time transmitter, you can control the time of multiple radio clocks within 10m with this one unit. We can cover it. Depending on the structure of the room, radio waves may not be able to pass through, so it cannot be said that all rooms can be covered, but with this transmitter you can continue to use the clock even if you buy a new one, so it is economical.
