Casio MO0804-EA Manual De Usuario

• The watch takes from two to 14 minutes to receive the time calibration

signal whenever a calibration time is reached. Do not perform any button
operation within 14 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 current

time in the Timekeeping Mode. The receive operation will be performed
whenever the display shows any one of the calibration times, regardless of
whether or not the displayed time actually is the correct time.

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. The receiving indicator is displayed while an auto
or manual receive operation is in progress.

• 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 5 receiving indicator will remain on the
display in all modes. The Level 5 receiving indicator will not be displayed if
signal reception was unsuccessful or after you adjust the current time
setting manually.

• The Level 5 receiving indicator is displayed only when the watch is able to

receive both time and date data successfully. It does not appear when only
time data is received.

• The Level 5 receiving indicator indicates that at least one of the auto

calibration signal receive operations was successful. Note, however, that
the indicator disappears from the display each day at the start of the first
auto receive operation of the day.

1. Enter the Receive Mode.
2. Place the watch on a stable surface so its 12

o’clock side is facing towards a window.

3. Hold down D for about two seconds until 

RC

starts to flash on the display.

• Time calibration signal reception takes from

two to seven minutes, but in some cases it can
take as long as 14 minutes.Take care that you
do not perform any button operations or move
the watch during this time.

• If the receive operation is successful, the

reception date and time appear on the display,
along with the 

GET

 indicator.

The watch will enter the Receive Mode if you
press D or if you do not perform any button
operation for about one or two minutes.

• If the current reception fails but a previous

reception was successful, the display shows
the previous reception’s date and time, and the

ERR

 indicator.  

 indicates that none of

the reception operations have been successful
during the current date.
The watch will enter the Receive Mode without
changing the time setting if you press D or if
you do not perform any button operation for
about one or two minutes.

• To interrupt a receive operation and return to

the Receive Mode, press D.

If there was a previously
successful reception

If no reception has
been successful

1. Enter the Receive Mode.
2. In the Receive Mode, hold down A until the

current auto receive setting (

ON

 or 

OFF

)

starts to flash. This is the setting screen.

• Note that the setting screen will not appear

if the currently selected Home City is one
that does not support time calibration
reception.

3. Press D to toggle auto receive on (

ON

) and

off (

OFF

).

4. Press A to exit the setting screen.

• For information about city codes that support

signal receive, see “To specify your Home City”.

Enter the Receive Mode.

• When receive is successful, the display shows

the time and date that receive was successful.

 indicates that none of the reception

operations were successful.

• To return to the Timekeeping Mode, press C.

•The watch is not in the Receive

Mode.

•Your current Home City is one

that does not support signal
reception.

•You changed the time setting

manually.

•You changed the DST setting of

your Home City in the World
Time Mode.

•You pressed a button while

signal receive was in progress.

•Even if receive is successful,

the Level 5 receiving indicator
disappears from the display
each day when the first auto
receive operation of the day is
performed.

•Time data (hour, minute,

second) only was received
during the last receive
operation. The Level 5 receiving
indicator appears only when
time data and date data (year,
month, day) are both received.

Cannot perform
manual receive.

Auto receive is
turned on, but
the Level 5
receiving
indicator does
not appear on
the display.

•Enter the Receive Mode

and try again.

•Select one of the

following as your Home
City: LON, PAR, BER,
ATH, HKG, SEL, TYO,
HNL, ANC, LAX, DEN,
CHI, or NYC.

•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.

Check the following points whenever you experience problems with signal
reception.

•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.

•Change the DST setting

following signal
reception.

• For further information, see “Important!” under “Time Calibration Signal

Reception” and “Radio-controlled Atomic Timekeeping Precautions”.

This watch uses a pressure sensor to measure air pressure (barometric
pressure) and a temperature sensor to measure temperature.

• You can calibrate the pressure sensor and the temperature sensor if you

suspect that readings are incorrect.

Pressing B in the Timekeeping Mode or
Altimeter Mode enters the Barometer/
Thermometer Mode and starts barometric
pressure and temperature measurements
automatically .

• It can take up to four or five seconds for the

barometric pressure reading to appear after
you enter the Barometer/Thermometer Mode.

• Barometric pressure is displayed in units of

1hPa (or 0.05 inHg).

• The displayed barometric pressure value

changes to xxxx hPa (or inHg) if a measured
barometric pressure falls outside the range of
260 hPa to

1100 hPa (7.65 inHg to 32.45

inHg). The barometric pressure value will
reappear as soon as the measured barometric
pressure is within the allowable range.
