Digital Compass Reading Precautions Location During Use Taking readings near sources of strong magnetism can cause reading error. Keep the watch away from the following types of items. Permanent magnets (magnetic accessories, etc.), metal objects, high-voltage wires, aerial wires, electrical household appliances (TVs, computers, cellphones, etc.) ● Note that correct direction readings are not possible indoors, especially inside of reinforced concrete structures. ● Accurate direction readings are not possible in motor vehicles, on boats, on aircraft, etc. Storage Location Exposure of the watch to magnetism can affect the accuracy of digital compass readings. Keep the watch away from the types of items below. Permanent magnets (magnetic accessories, etc.), metal objects, electrical household appliances (TVs, computers, cellphones, etc.) Altitude Measurement The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor. Important! ● The altitude readings displayed by the watch are relative values that are calculated based on barometric pressure measured by the watch’s pressure sensor. This means that barometric pressure changes due to weather can cause altitude readings taken at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/ or sea level elevation indicated for the area where you are located. When using the watch’s altimeter while mountain climbing, it is recommended that you regularly calibrate its readings in accordance with local altitude (elevation) indications. l Calibrating Altitude Readings ● When using navigation while receiving GPS signals, measured altimeter values are automatically adjusted in accordance with GPS signal data. Note, however, that this may result in some difference between the measured value and the actual altitude. Also note that the measured altitude value adjustment operation using GPS signal data may take a few minutes. The adjustment operation may take even longer, depending on your current environment. Regular manual adjustment of the measured altitude value using locally available information is recommended. The watch will not use GPS signal data to adjust measured altitude values for one hour after you adjustment the measured altitude value manually. ● The altitude correction value and barometric pressure changes may result in display of a negative value. ● Check the information below to find out about how to minimize differences between readings produced by the watch, and values provided by local altitude (elevation) indications. l Altitude Reading Precautions Getting ready Enter the Altimeter Mode. l Navigating Between Modes l Specifying Display Contents ● Entering the Altimeter Mode starts altitude readings.

Watch readings are different from altitude information available from other sources. Correct altitude readings are not possible. Relative altitude is calculated based on changes in barometric pressure measured by the watch’s pressure sensor. This means that barometric pressure changes can cause readings taken at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located. When using the watch’s altimeter while mountain climbing, it is recommended that you regularly calibrate its readings in accordance with local altitude (elevation) indications. l Calibrating Altitude Readings Q2 [-----] appears on the display following altitude differential measurement. [-----] appears when the altitude differential is outside the allowable measuring range (±3,000 m). If [ERROR] appears on the display, there may be a problem with the sensor. l Setting a Reference Altitude and Taking Relative Altitude Readings Q3 [ERROR] appears during measurement. There may be a problem with the sensor. Try taking another measurement. If [ERROR] keeps appearing after multiple measurement attempts, contact a CASIO service center. Operation Guide 3452 40
