• Even when the watch is within range of a transmitter, signal reception may be impossible due to the 
effects of geographic contours, structures, weather, the time of year, the time of day, radio interference, 
etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the 
infl uence of the conditions listed above becomes even greater.
• Signal reception may not be possible at the distances noted below during certain times of the year or 
day....

Using Bearing Memory
Bearing Memory lets you temporarily store and display a direction reading 
so you can use it as a reference as you take subsequent digital compass 
readings. The Bearing Memory screen displays the direction angle for the 
stored reading, along with an indicator that indicates the stored reading.
When you take digital compass readings while the Bearing Memory 
screen is displayed, the direction angle of the current digital compass 
reading (as read from the...

Barometric Pressure• Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg).•The displayed barometric pressure value changes to - - -
 if a measured 
barometric pressure falls outside the range of 260 hPa to 1,100 hPa (7.65 
inHg to 32.45 inHg). The barometric pressure value will reappear as 
soon as the measured barometric pressure is within the allowable range.
Temperature• Temperature is displayed in units of 0.1°C (or 0.2°F).• The displayed temperature value...

Session end point
The total ascent and total descent values produced by an Altimeter Mode measurement session during 
the example climb illustrated above are calculated as follows.
  Total Ascent:
q (300 m) + e (620 m) = 920 m
  Total Descent: w (320 m) + r (500 m) = 820 m• Entering the Altimeter Mode starts a new altitude auto measurement session, but it does not reset the

Precautions Concerning Simultaneous Measurement of Altitude and Temperature
Though you can perform altitude and temperature measurements at the same time, you should remember 
that each of these measurements requires different conditions for best results. With temperature 
measurement, it is best to remove the watch from your wrist in order to eliminate the effects of body heat. 
In the case of altitude measurement, on the other hand, it is better to leave the watch on your...
