※ The watch may be able to receive radio
signals outside a reception range if the
receiving conditions are favorable.
※ The watch may fail to receive radio signals
depending on the reception conditions
(w e a t he r, ge o g r aphic lo c a tio ns, r adio
disturbances such as tall buildings, and
orientation of the watch).
