About This Manual
•The operational procedures for Modules 2735, 3747, and 4772 are identical. All of
the illustrations in this manual show Module 2735.
•Button operations are indicated using the letters shown in the illustration.
•This watch does not have a time zone that corresponds to the Greenwich
Mean Time differential of –3.5 hours. Because of this, the radio-controlled
timekeeping and World Time functions will not display the correct time for
Newfoundland, Canada.

Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates
its time setting accordingly. The time calibration signal
includes both Standard Time and Daylight Saving Time
(summer time) data.
•This watch is designed to pick up the time calibration
signal transmitted from Fort Collins, Colorado (USA).
Reception is possible within North America*.
*
The term “North America” in this User’s Guide refers to the
area that consists of Canada, the continental United States,
and Mexico.
Current Time Setting
This watch automatically adjusts its digital time setting in
accordance with a time calibration signal. You can also
perform a manual procedure to set the time and date,
when necessary.

•The first thing you should do after purchasing this watch is to set your Home City,
which is the city where you will normally use the watch. For more information, see
“To set your Home City” below.
•When using the watch outside of the range of the transmitter in Fort Collins, you
need to manually adjust the time as required. See “Timekeeping” for information
about manual settings.
•The analog time of this watch is synchronized with the digital time. Because of this,
the analog time setting is automatically adjusted whenever you change the digital
setting. See “Analog Timekeeping” for more information.
To set your Home City
1. In the Timekeeping Mode, hold down A until the
transmitter indicator (USA) starts to flash, which
indicates the setting screen.
2. Press C to display the city code setting screen.
3. Use D(east) and B(west) to select the city code you
want to use as your Home City.
•The following are the city codes for major cities in
North America.

•The first press of A displays the 12/24-hour setting
screen. Pressing A again exits the setting screen.
Important!
•Normally, your watch should show the correct time as soon as you select your Home
City code. If it does not, it should adjust automatically after the next auto receive
operation (in the middle of the night). You can also perform manual receive or you
can set the time manually.
•If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST setting.
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
•Auto Receive
With auto receive, the watch automatically picks up the time calibration signal four
times a day at 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m. For more information,
see “About Auto Receive”.
Important!
•Position the watch as shown in the nearby illustration, with its 12 o’clock side facing
towards a window. Make sure there are no metal objects nearby.
Resin Band Metal Band
•The watch should not be on its side or facing the wrong way.
•Proper signal reception can be difficult or even impossible under the conditions listed
below.
•Signal reception is normally better at night than during the day.
•Time calibration signal reception takes from two to six minutes, but in some cases it
can take as long as 12 minutes. Take care that you do not perform any button
operations or move the watch during this time.

•At distances further than about 600 miles (1,000 kilometers) from the transmitter,
signal reception may not be possible during certain times of year or times of day.
Radio interference may also cause problems with reception.
•Even when the watch is within the reception range of the transmitter, signal
reception is impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.

•Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
•See the information under “Signal Receive Troubleshooting” if you experience
problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the digital time in the Timekeeping Mode reaches 2:00 a.m.,
3:00 a.m., 4:00 a.m., and 5:00 a.m. each day (calibration times).
•Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive”.
Operation Guide COMBIWAVE1
2
Note
•The auto receive operation is performed only if the watch is in the Timekeeping
Mode or World Time Mode when one of the calibration times is reached. It is not
performed if a calibration time is reached while an alarm is sounding, or while you
are configuring settings (while settings are flashing on the display).
•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.
•When auto receive is turned on, the watch receives the calibration signal for two to
six minutes everyday when the digital time in the Timekeeping Mode reaches each
of the calibration times. Do not perform any button operation within six minutes
before or after any one of the calibration times. Doing so can interfere with correct
calibration.
•Remember that reception of the calibration signal depends on the time kept in the
digital display. The receive operation will be performed whenever the display shows
any one of the calibration times, regardless of whether or not the displayed time is
actually the correct time.
•When two, three, or four 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.
About the Receiving Indicator
The receiving 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.
•Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receiving indicator to indicate signal strength.
•Use the receiving indicator as a guide for checking signal strength and for finding the
best location for the watch during signal receive operations.

(Level 1) (Level 4)
•Following reception of the time calibration signal and calibration of the watch’s time
setting, the Level 4 receiving indicator will remain on the display in all modes. The
Level 4 receiving indicator will not be displayed if signal reception was unsuccessful
or after you adjust the current time setting manually.
•The Level 4 receiving indicator is displayed 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 Level 4 receiving indicator indicates that at least one of the auto calibration
signal receive operations was successful. Note, however, that the Level 4 receiving
indicator is cleared from the display at 3:00 a.m. each day.
To perform manual receive
1. Place the watch on a stable surface so its top (12
o’clock side) is facing towards a window.
2. In the Timekeeping Mode, hold down D for about two
seconds until the watch beeps.
3. Release D and the current time flashes to indicate that
signal reception has started.
•Time calibration signal reception takes from two to six
minutes. Take care that you do not perform any button
operations or move the watch during this time.
•After signal reception is complete, the display of the
watch changes to the Last Signal screen.
Note
•To interrupt a receive operation and return to the Timekeeping Mode, press D.
•If the receive operation is unsuccessful, the message ERR appears on the display
for about one or two minutes. After that, the watch returns to the Timekeeping Mode.
•You can also change from the Last Signal or ERR screen to the normal
timekeeping screen by pressing D.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto return features
•If you leave the watch in the Alarm (except for the target alarm screen explained on
“To set an alarm time”), Date Alert or Hand Setting Mode for two or three minutes
without performing any operation, it automatically changes to the Timekeeping
Mode.
•If you leave the watch with a flashing setting on the display for two or three minutes
without performing any operation, it automatically saves any settings you have made
up to that point and exits the setting screen.
Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Initial Screens
When you enter the World Time, Alarm, or Date Alert Mode, the data you were
viewing when you last exited the mode appears first.
Radio-controlled Atomic Timekeeping Precautions
•Strong electrostatic charge can result in the wrong time being set.
•The time calibration signal is bounced off the ionosphere. Because of this, such
factors as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
•Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.

•The current time setting in accordance with the time calibration signal takes priority
over any time settings you make.
•The watch is designed to automatically update the date and day of the week for the
period January 1, 2000 to December 31, 2039. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2040.
•This watch can receive signals that differentiate between leap years and non-leap
years.
•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.
•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.
•If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time within ±20 seconds a month at normal temperature.
•If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your current city code, DST (summer
time), and auto receive settings. The following are the initial factory defaults for these
settings.

Timekeeping
•Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
•The day of the week is automatically displayed in accordance with the date (year,
month, and day) settings.
•The year can be set in the range of 2000 to 2039.
•The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
•The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Greenwich Mean Time (GMT) differential for each
city, based on your Home City time setting.
•GMT differential is calculated by this watch based on UTC* data.
* The letters “UTC” stands for “Universal Time Coordinated,” which is the world-wide scientific
standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that
keep time accurately to within microseconds. Leap seconds are added or subtracted as
necessary to keep UTC in sync with the Earth’s rotation. The reference point for UTC is
Greenwich, England.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.
•With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
•With the 24-hour format, times are displayed in the range of 0:00 to 23:59. The
indicator 24 indicates the 24-hour format.
Illumination Precautions
The watch has an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark. In any mode, press B to illuminate the display for
about one second.
•The electro-luminescent panel that provides illumination loses power after very long
use.
•Illumination may be hard to see when viewed under direct sunlight.
•The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
•Illumination turns off automatically whenever an alarm sounds.
•Frequent use of illumination runs down the battery.
