As well as cyclocomputer function, this model has altimeter function, which measures altitude and atmospheric temperature, by sensing the changes of the atmospheric pressure with the pressure-sensor. When cycling in a hilly area with a mountain bike, it gives the current altitude (above sea level) and trip altitude gain in the 1 meter resolution. In addition to functions for the bicycling activity, it can be used on its own as an independent altimeter for mountain climbing. [. . . ] At venues of which altitudes are under 500m, the pressure decreases by approx. 12hPa per each 100m (Table 1). Weather and Barometric Pressure Changes Changes in weather from a HIGH PRESSURE system (clearer, calmer weather) to a LOW PRESSURE system (over-cast, rain, storming weather) can cause a change in the Altitude reading of 300 feet or more. Thunderstorms or other strong low pressure weather conditions, you 9 E Fig. 10 may cause even a greater change. In seemingly stable weather conditions, you may expect to see the Altitude fluctuate as much as 100 feet from morning to evening because of the warming aspects of the sun on the atmosphere.

In this way, the change of the pressure will have an influence on the altitude data only when the unit perceives the speed signal, regardless of start/stop. Thus, the altitude data will not be affected even if pressure changes occur while bicycle is stopped. Note: If the pressure changes while riding, the altitude data will give an error. Continuous Measuring Mode (Bicycle Symbol: off) When using this unit on its own apart from a bicycle, for hiking etc. , switch off the bicycle symbol. In this way, the altitude data is always influenced by the change of the pressure (Fig. · In this mode, if the Auto (automatic start/stop) function is on, the elapsed time cannot be measured; switch off the AT symbol and operate with the S/S button in each start/stop. (Refer to "Auto Function", page 12. ) Note: As the pressure changes constantly, the altitude data will give an error to some extent. * Release the power saving function by pressing the S/S button or the Mode button.

How to Switch on/off the Bicycle Symbol To switch on(off) the bicycle symbol, first display the sub mode showing trip altitude gain and total altitude gain, with the operation of the Mode button, and press the Set button. Then press the Set button again, and the bicycle symbol will be switched on(off). 5. How to Correct the Current Altitude Air pressure changes constantly, due to various weather conditions. It is recommended to make corrections whenever a reliable index (such as map or peak pointer) is available. * The basic knowledge of the altitudes of your house, public facilities, etc. will be useful information for correction. 10 How to Correct the Altitude First display the main mode showing , with the operation of the Mode button. Press the Set button when the speed is zero, and it turns to the correction mode (Fig. 13). The figure increases with each press of the S/S button, and decreases with each press of the Mode button. Adjust the figure to the correct altitude, and press the Set button to complete this operation. E Fig. 13 HOW TO USE AS A CYCLOCOMPUTER Sensor Band B 1. Mounting to Bicycle · Attach the magnet on the right spokes of the front wheel. [. . . ] Replace the bracket & sensor part with a new one. Transmission signal loss in damp or wet conditions. Water or condensation may collect between the bracket sensor and the computer causing an interruption in the data transmission. Contacts can also be treated with a water repellent silicon jell from an automotive parts or hardware store. Do not use industrial water repellent; it may damage the bracket. The S/S button does not start/stop measuring. [. . . ]
