E-96
■
Correct altitude readings are not possible.
Relative altitude is calculated based on changes in barometric pressure readings by the pressure sensor.
To minimize the chance of reading error due to changes in barometric pressure, you should update the
reference altitude value before setting off on a trek or any other activity where you plan to take altitude
readings. For more information, see “To specify a reference altitude value” (page E-44).
■
ERR appears on the display after I perform 2-point calibration.
If
- - -
appears and then changes to
ERR
(error) on the calibration screen, it means that there is something
wrong with the sensor.
•
If
ERR
disappears after about one second, try performing the calibration again.
•
If
ERR
keeps appearing, contact your original dealer or nearest authorized CASIO distributor to have
the watch checked.
Whenever you have a sensor malfunction, take the watch to your original dealer or nearest authorized
CASIO distributor as soon as possible.
■
What causes incorrect direction readings?
•
Incorrect 2-point calibration. Perform 2-point calibration (page E-52).
•
Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel
beam, overhead wires, etc., or an attempt to take direction readings on a train, boat, etc. Move away
from large metal objects and try again. Note that digital compass operation cannot be performed inside
a train, boat, etc.
E-97
■
What causes different direction readings to produce different results at the same location?
Magnetism generated by nearby high-tension wires is interfering with detection of terrestrial magnetism.
Move away from the high-tension wires and try again.
■
Why am I having problems taking direction readings indoors?
A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism
readings. Move away from the object causing the interference or take the direction reading outdoors.
Indoor direction readings are particularly diffi cult inside ferro-concrete structures. Remember that you will
not be able to take direction readings inside of trains, airplanes, etc.
■
The barometric pressure differential pointer does not appear on the display when I enter the
Barometer/Thermometer Mode.
•
This could indicate sensor error. Try pressing
B
again.
•
The barometric pressure differential pointer is not displayed when the displayed current barometric
value is outside of the allowable measurement range (260 to 1,100 hPa).
World Time Mode
■
The time for my World Time City is off in the World Time Mode.
This could be due to incorrect switching between standard time and daylight saving time. See “To specify
standard time or daylight saving time (DST) for a city” (page E-76) for more information.
Charging
■
The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 5 (page E-11). Continue exposing the watch to light
until the battery power indicator shows H or M.

Possible Cause
Remedy
Page
•
You are wearing or moving the
watch, or performing a button
operation during the signal
receive operation.
•
The watch is in an area with
poor reception conditions.
Keep the watch in an area where reception conditions are good
while the signal receive operation is performed.
E-17
You are in an area where signal
reception is not possible for
some reason.
See “Approximate Reception Ranges”.
E-16
The calibration signal is not
being transmitted for some
reason.
•
Check the website of the organization that maintains the time
calibration signal in your area for information about its down times.
•
Try again later.

■
The current time setting changes after I set it manually.
You may have the watch confi gured for auto receive of the time calibration signal (page E-18), which will
cause the time to be adjusted automatically according to your currently selected Home City. If this results
in the wrong time setting, check your Home City setting and correct it, if necessary (page E-31).

Signal reception on a day for

may have failed for some reason.
Perform the operation under “To get ready for a receive operation”.
The time setting will be adjusted automatically as soon as signal
reception is successful.

If you are unable to receive the time calibration signal, change the
standard time/daylight saving time (DST) setting manually.
