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.
2. Cycling Mode (Bicycle Symbol: on) (Fig. 10)
When using this unit on bicycle, switch on the bicycle symbol. 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. (Fig.
11).
Note: If the pressure changes while riding, the altitude data will give an error.
3. 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. 12).
• 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.

4. 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. As such, while riding, it is necessary to correct
the altitude. 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.
