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 signals transmitted from Mainflingen (Germany), Rugby
(England), or Fort Collins (the United States) include 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 signals.
• The time calibration signals transmitted from Fukushima and Fukuoka/Saga (Japan)
do not include summer time data.
• The default DST setting is Auto DST (
PAR, ROM, BER, STO, ATH, MOW, HKG, BJS, TPE, SEL, TYO, HNL, ANC, YVR,
LAX, YEA, DEN, MEX, YWG, CHI, MIA, YTO, NYC, YHZ, or YYT as your Home City
code.
• If you experience problems receiving the time calibration signal in your area, it
probably is best to switch between Standard Time and Daylight Saving Time
(summer time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down A until the city code starts to flash, which
indicates the setting screen.
2. Press C and the DST setting screen appears.
3. Use D to cycle through the DST settings in the sequence shown below.

functions of this watch.
Button Operation Tone
Module 3050 (A)
The button operation tone sounds any time you press one
of the watch's buttons. You can turn the button operation
tone on or off as desired.
• Even if you turn off the button operation tone, the alarm,
Hourly Time Signal, and Countdown Timer Mode alarm
all operate normally.

Module 3061
In any mode (except when a setting screen is on the
display), hold down C to toggle the button operation tone
on (MUTE indicator not displayed) and off (MUTE
indicator displayed).
• Since the C button is also the mode change button, holding it down to turn the
button operation tone on or off also causes the watch's current mode to change.
• The MUTE indicator is displayed in all modes when the button operation tone is
turned off.
Power Saving Function
When turned on, the Power Saving function enters a sleep
