Illumination turns off automatically whenever an alarm sounds The watch may emit an audible sound whenever the display is illuminated This is due to vibration of the EL panel used for illumination and does not indicate malfunction Frequent use of illumination runs down the battery Auto light switch precautions e The auto light switch is turned off automatically whenever battery power is at Level 4 Wearing the watch on the inside of your wrist movement of your arm or vibration of your arm can cause frequent activation of the auto light switch and illumination of the display To avoid running down the battery turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the display and can run down the battery More than 15 degrees e Illumination may not turn on if the face of the too high watch is more than 15 degrees above or below parallel Make sure that the back of your hand is parallel to the ground NG e Illumination turns off in about one second even if you keep the watch pointed towards your face Static electricity or magnetic force can interfere with proper operation of the auto light switch If illumination does not turn on try moving the watch back to the starting position parallel with the ground and then tilt it back towards your face again

5. If this does not work drop your arm all the way down so it hangs at your side and then bring it back up again Under certain conditions illumination does not turn on until about one second after you turn the face of the watch towards you This does not necessarily indicate malfunction You may notice a very faint clicking sound coming from the watch when it is shaken back and forth This sound is caused by mechanical operation of the auto light switch and does not indicate a problem with the watch CASIO Barometer and Thermometer Precautions e The pressure sensor built into this watch measures changes in air pressure which you can then apply to your own weather predictions It is not intended for use as a precision instrument in official weather prediction or reporting applications e Sudden temperature changes can affect pressure sensor readings e Temperature measurements are affected by your body temperature while you are wearing the watch direct sunlight and moisture To achieve a more accurate temperature measurement remove the watch from your wrist place it in a well ventilated location out of direct sunlight and wipe all moisture from the case It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature Pressure Sensor and Temperature Sensor Calibration The pressure sensor and temperature sensor built into the watch are calibrated at the factory and normally require no fu

11. other activity where there is the chance of sudden altitude changes Do not use this watch for taking altitude readings in applications that demand professional or industrial level precision Remember that the air inside of a commercial aircraft is pressurized Because of this the readings produced by this watch will not match the altitude readings announced or indicated the flight crew How the Altimeter Measures Altitude The altimeter can measure altitude based on its own preset values or a reference altitude specified by you When you measure altitude based on preset values Data produced by the watch s barometric pressure sensor is converted to approximate altitude based on ISA International Standard Atmosphere conversion values stored in watch memory When you measure altitude using a reference altitude specified by you After you specify a reference altitude the watch will use that value to convert the current barometric pressure reading to altitude e When mountain climbing you can specify a reference value in accordance with a marker along the way or altitude information from a map After that altitude readings produced by the watch will be more accurate than they would without a reference altitude Displaying Your Current Altitude You can use the procedure described in this section to display your current altitude If you leave the watch in the Altimeter Mode it will update the displayed altitude value regularly and
