[R] is flashing on the digital display.
[R] may appear on the display when the
watch’s battery power is low, or if you use the
light or other function 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, are
disabled.
If [R] remains on the display or if it keeps
appearing, it may indicate that the battery
needs to be replaced.
