Specifications - Casio Pro Trek PRW-2000-1ER Operation Manual

• Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer/
Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available
to power it suffi ciently. In this case, ERR will appear on the display. This does not indicate malfunction,
and sensor operation should resume once battery voltage returns to its normal level.
• If ERR keeps appearing during measurement, it could mean there is a problem with the applicable
sensor.
■ ERR appears on the display after I perform bidirectional calibration or northerly 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.
■ ERR appears on the display after I perform northerly calibration.
The ERR message indicates there may be some problem with the sensor. The ERR message also may
be due to movement of the watch while the calibration procedure is being performed. Try performing
calibration again, taking care to ensure that the watch is not moved.
If this does not solve the problem, the problem may be due to some nearby source of terrestrial
magnetism. Try performing the calibration procedure again from the beginning.
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 bidirectional calibration. Perform bidirectional calibration.
• Nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel
beam, overhead wires, etc., or an attempt to perform direction measurement 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.
■ 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" 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. Continue exposing the watch to light until the
battery power indicator shows "H" or "M".
Time Calibration Signal
The information in this section applies only when LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW,
HKG, BJS, HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI, NYC, YHZ, YYT, SEL, or TYO is selected at the
Home City. You need to adjust the current time manually when any other city is selected as the Home City.
■ The display shows the ERR indicator when I check the result of the latest receive operation.

■ 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, 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.
