• 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.
• 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.
• The receive indicator indicates that at least one of the three calibration signal
receive operations was successful. Note, however, that the receive indicator is
cleared from the display at 3:00 AM each day.

Auto Receive" for details.
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signal transmitted from Mainflingen includes both Standard Time
and DST data. When the Auto DST setting is turned on, the watch switches between
Standard Time and DST (summer time) automatically in accordance with the
Mainflingen signal.
• The default DST setting is Auto DST (
A
) whenever you select
or
ATH
as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it is
probably best to switch between Standard Time and Daylight Saving Time (summer
time) manually.
To change the Daylight Saving Time (summer time) setting
1. From the Timekeeping Mode, use C and A to display
in the text area.
2. Press B to enter the Time Setting Mode.
3. Press B twice so
