Q2
[R] is flashing on the display.
[R] may appear on the display when the
watch's battery power is low, or if you use the
light or other functions a number of times
during a short period, which momentarily
causes the battery level to go low. If this
happens, all watch functions, except for
timekeeping, become disabled.
If [R] remains on the display or if it keeps
appearing, it may indicate that the battery
needs to be replaced.
Request battery replacement from a CASIO
service center or your original retailer.
