Casio 3069 Watch User Manual


 
E-20
Even when the watch is within the reception range of a transmitter, signal
reception may be impossible at times due to the effects of geographic
contours, structures, weather, the season of the year, the time of day, radio
interference, etc. Note that the signal becomes weaker at distances of
approximately 500 kilometers from the transmitter, which means that the
influence of the conditions listed above becomes even greater.
About Auto Receive
The watch receives the time calibration signal automatically up to six times a
day. When any auto receive is successful, the remaining auto receive
operations are not performed. The reception schedule (calibration times)
depends on your currently selected Home City, and whether standard time or
Daylight Saving Time is selected for your Home City.
