To perform manual receive
1. Place the watch on a stable surface so its 12 o’clock
side is facing towards a window (page E-23).
2. In the Timekeeping Mode, hold down A for about two
seconds.
3. The second hand will move to READY (R) to indicate
that the watch is setting up for time calibration
reception.
• The second hand will move to WORK (W) and stay there
while actual reception is in progress.
• If signal reception is unstable during reception, the
second hand may move between WORK (W) and
READY (R).
• The hour and minute hands continue to keep time
normally.
