Q&A regarding radio-controlled watches/clocks
Q1 How does a radio-controlled watch/clock work?
Q2 In what environment does my radio-controlled watch/clock receive standard electric wave?
Q3 Why does my radio-controlled watch/clock gain or lose time?
Q4 Is my radio-controlled watch/clock affected by magnetism?
Q5 How long does it take for my radio-controlled watch/clock to complete radio wave reception?
Q6 Does my radio-controlled watch/clock have influence on the human body or medical equipment?
Q7 My radio-controlled watch/clock has suddenly stopped receiving radio waves. Why?
Q8 Why don't radio-controlled clocks with analogue displays have any setting stem?
Q9 What are appropriate measures to be taken when my radio-controlled clock cannot display the correct time or a malfunction is observed immediately after battery replacement?

Q5 How long does it take for my radio-controlled watch/clock to complete radio wave reception?

Sometimes it takes 10 minutes or longer, depending on reception environments.
It takes one minute to transmit a complete time code carried by the standard radio waves. As reception may be interfered due to radio noise, it is necessary for a radio-controlled watch/clock to detect several different time codes for verification. Therefore it takes time until the correct time data is determined.
