As a rough guide, radio signal reception range is within an
approximate radius of 1500 kilometers from the transmitting station.

■ To Improve radio signal reception
・ Place the watch in a place where it can easily receive a radio signal such as near a window.
The antenna is embedded at the 12 o clock position of the watch. Turning the antenna toward the
outside of a window or the direction facing transmitting stations helps improve radio signal reception.
※ Locations of transmitting stations → Radio signal reception range P118
・Do not move the watch while it is receiving radio signals.
To enhance the reception of radio signals, do not move the wat ch or do not
change the orientation of the watch while it is receiving radio signals.
※ If the button is operated while the watch is receiving a radio signal, the reception will be cancelled.
・ T he watch may display the wrong time if it fails to receive radio signals properly
because of interference. The watch may also fail to receive radio signals
properly depending on the location or radio wave receiving conditions. In this
case, move the watch to another place where it can receive radio signals.
・ W hen the watch is out of reception range, its accurate quartz movement (loss /
gain: ± 15 seconds per month on average) will continue to keep the time.
・ T he time signal transmission may be stopped during maintenance of the
facilities of each transmitting station or because of a lightning strike. In such
a case, see each station's website for further information or contact SEIKO
CUSTOMER SERVICE CENTER.
