How to use the altimeter (ALTI) mode
The current altitude and climbing speed are measured and displayed.
The current altitude and climbing speed are measured every 10 seconds and the measurement
stops when 12 hours have elapsed. When Button Ⓕ is pressed, re-measurement can be made.
Maximum 10 times of mountaineering data, of which one time is 24 hours, such as average climbing
speed can be recorded.
【CAUTION】 I f watch temperature changes when altitude is measured, some errors
may occur in measurement. Make measurements in a state not aff ect-
4
ed by temperature change such as wearing the watch on your arm.
【Caution】 W hen water runs directly from a faucet onto the watch, very high water pressure is ap-
plied. The measurement accuracy of the sensor to measure pressure temporarily de-
grades, and the values of altitude and atmospheric pressure may fl uctuate. If very high
water pressure is applied to the body of the watch, wait for about 10 minutes or more un-
til the measurement accuracy of the pressure sensor recovers and then measure again.
【Caution】 P lease avoid getting water dripped directly on the watch by wearing a raincoat when you use the watch in the rain.
Please stop recording about 10 minutes until the sensor accuracy recovers if water drips onto the watch in case of
a sudden downpour.
The altimeter is based on the barometer which might be incorrect because of the sensor getting splashed with
water such as rain.
