About the Receive Indicator
The receive indicator shows the strength of the calibration signal being received. For best
reception, be sure to keep the watch in a location where signal strength is strongest.
Weak
• Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receive indicator to indicate signal strength.
• Use the receive indicator as a guide for checking signal strength and for finding the
best location for the watch during signal receive operations.
• The receive indicator remains on the display in all modes following reception of the
time calibration signal and calibration of the watch's time setting. The receive
indicator does not appear if signal reception was unsuccessful or after manual
adjustment of the current time setting.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches 2:00 AM, 4:00 AM
and 6:00 AM each day (calibration times).
Note
• The auto receive operation is performed only if the watch is in the Timekeeping or
World Time Mode when one of the calibration times is reached.
It is not performed if a calibration time is reached while you are making settings
(while settings are flashing on the display), while an alarm is sounding.
• Auto receipt of the calibration signal is designed to be performed early in the
morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
Before going to bed for the night, remove the watch from your wrist, and put it in a
location where it can easily receive the signal.
• The receive indicator indicates that either the 2:00 AM, 4:00 AM, or 6:00 AM
calibration signal reception was successful. Note, however, that the receive indicator
is cleared from the display at 3:00 AM each day.
• If you do not see the receive indicator except for the above reason, it means there
was some problem with the calibration reception operation. Either perform reception
manually, or make sure the watch is set up properly to receive the time calibration
signal for the next automatic reception time.
• Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.
• The receive indicator (
) appears only when the watch is able to successfully
receive both time and date data. It does not appear when only time data is received.
When time and date data is received: Receive indicator (
When time data only is received: Receive indicator (
• Normally, the signal reception date shown by the Last Signal screen is the date data
included in the received time calibration signal. When only time data is received,
however, the Last Signal screen shows date as kept in the Timekeeping Mode at the
time of signal reception.
• When auto receive is turned on, the watch receives the calibration signal for two to
six minutes each day when the Timekeeping Mode time reaches 2:00 AM, 4:00 AM
and 6:00 AM. Do not operate any of the watch's buttons within six minutes prior to or
following the calibration times. Doing so can interfere with correct calibration.
• Remember that reception of the calibration signal depends on the time kept in the
Timekeeping Mode. The receive operation will be performed whenever the display
shows 2:00 AM, 4:00 AM and 6:00 AM, regardless of whether or not the
Timekeeping Mode time is actually the correct time.
• When two or three receptions are successful, the watch uses the data of the last
reception for calibration. When only one reception is successful, the watch uses the
data of the successful reception.
