Signal Level Indicator
During calibration signal reception, the signal level indicator displays the
signal level as shown below.
Weak (Unstable)
The level indication will change in accordance with reception conditions
while reception is being performed.
As you watch the indicator, keep the watch in a location that best
maintains stable reception.
• Even under optimum reception conditions, it can take about 10
seconds for reception to stabilize.
• Note that weather, the time of day, surroundings, and other factors all
can affect reception.

To turn auto receive on or off
1. Enter the Receive Mode (page E-32).
• R/C will be displayed for about one second, and then the date (month and day) and the time of the
last signal reception will alternate on the digital display.
• Dashes (- : - - and -.- -) alternating in place of the date and time indicate there has been no
successful signal reception yet (since you purchased the watch or had its battery replaced).
2. Pull out the crown. This will cause the current auto receive status (ON or OFF) to fl ash on the digital
display.
• Only AUTORC OFF is displayed for cities that do not support time calibration signal reception.
AUTORC ON is not displayed.
3. Rotate the crown to select either auto receive on (ON) or auto receive off (OFF).
4. After the setting is the way you want, push the crown back in. This will return to the screen that was
displayed in step 1 of this procedure.
Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time setting.
• Even if a receive operation is successful, certain conditions can cause the time setting to be off by up
to one second.
• The watch is designed to update the date and day of the week automatically for the period January 1,
2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed
starting from January 1, 2100.
• If you are in an area where signal reception is not possible, the watch keeps time with the precision
noted in "Specifi cations".
