Take care that you do not perform any button operations or move the watch during this time. The time setting signals usually come from radio emitting towers. Casio Wave Ceptor is a line of radio watches by Casio.
What is the range for receiving the time calibration signal? The Wave Ceptor watches are not the only radio-controlled wristwatches on the market. Wave Ceptor watches are able to set themselves to the correct time by receiving time signals from various government time services around the world. This is because the watch is not making allowances for Daylight Saving Time (summertime). Change the watch’s DST setting* to «Auto DST», and it will adjust the hour setting automatically.
The following guidelines give an idea of the charging time required to recover from a single illumination operation. Their long-term and short-term accuracy is thus better than 500 ms. As with all radio-controlled watches they revert to free-running quartz accuracy in areas out of range or shielded from time setting signals, which gives them an accuracy equivalent to that of a standard quartz watch. Why is the time as set by the time calibration signal slightly different from the time indicated by the time signal on the TV, radio, etc.? After the watch receives the time calibration signal, it performs various calculations to determine the current time.
