Operation Guide COMBIWAVE1

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.

•
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
.

Problem
Cannot perform
manual receive.
Auto receive is
turned on, but
the Level 4
receiving
indicator does
not appear on
the display.
Time setting is
incorrect
following signal
reception.
Probable Cause
•
The watch is not in the Timekeeping Mode.
•
Your current Home City is not one of the
following city codes:
LAX
,
DEN
,
CHI
, or
NYC
.
•
You changed the time setting manually.
•
The watch was not in the Timekeeping
or World Time Mode, or you performed
some button operation during the auto
receive operation.
•
Even if receive is successful, the Level 4
receiving indicator disappears every day
at 3 am.
•
Time data (hour, minutes, seconds) only
was received during the last receive
operation. The Level 4 receiving
indicator appears only when time data
and date data (year, month, day) are
both received.
•
If the time is one hour off, the DST
setting may be incorrect.
•
The Home City code setting is not
correct for the area where you are using
the watch.
What you should do
•
Enter the Timekeeping Mode
and try again.
•
Select
LAX
,
DEN
,
CHI
, or
NYC
as your Home City.
•
Perform manual signal receive
or wait until the next auto
signal receive operation is
performed.
•
Check to make sure the watch
is in a location where it can
receive the signal.
•
Change the DST setting to
Auto DST.
•
Select the correct Home City
code.
Signal Receive Troubleshooting
Check the following points whenever you experience problems with calibration signal
reception.
•
For further information, see
“

under
“
Time Calibration Signal Reception
”
and

World Time
The World Time shows the current time in 30 cities (29
time zones) around the world.
•
If the current time shown for a city is wrong, check your
Home City time settings and make the necessary
changes.
•
The watch will perform a signal receive operation even if
it is in the World Time Mode when a calibration time is
reached. If this happens, the World Time Mode time
settings will be adjusted in accordance with the
Timekeeping Mode
’
s Home City time.
•
All of the operations in this section are performed in the
World Time Mode, which you enter by pressing
C
.
City Code

selected city code
To view the time in another city
While in the World Time Mode, press
D
to scroll through the city codes (time zones).
•
For full information on city codes, see the
“
City Code Table
”
.
To toggle a city code time between Standard Time and Daylight Saving Time
1. In the World Time Mode, use
D
to display the city code
(time zone) whose Standard Time/Daylight Saving Time
setting you want to change.
2. Hold down
A
to toggle Daylight Saving Time (

setting
”
for information about turning the Home City
code DST setting on and off.
DST indicator
•
The
DST
indicator is on the display whenever you display a city code for which
Daylight Saving Time is turned on.
•
Note that the DST/Standard Time setting affects only the currently displayed city
code. Other city codes are not affected.
Alarms
The Alarm Mode gives you a choice of four one-time
alarms and one snooze alarm. One of the one-time
alarms functions as a
“
target alarm,
”
which counts the time
remaining from the current Home City time to the target
alarm time.
Also use the Alarm Mode to turn the Hourly Time Signal
on and off.
•
There are five alarms named
AL1
,
AL2
,
AL3
,
TAL
(target alarm), and
SNZ
. You can configure
SNZ
as a
snooze alarm only. Alarms
AL1
,
AL2
,
AL3
, and
TAL
can be used as one-time alarms only.
