SETTING BAROMETRIC PRESSURE

The ALTIS is equipped with a highly sensitive barometer/weather station. The
barometer measures the Absolute Barometric Pressure and calculates the
Barometric Pressure corrected to Mean Sea Level (MSL). Barometric pressure
may be displayed in either Inches of Mercury (inHg) or Millibar/HectoPascals
(mbar/hpa).

In Barometer Mode:

NOTE:

There are four different Icons for weather.

SUNNY, PARTLY CLOUDY,

CLOUDY

and

RAIN

. Choose the icon which most closely matches the

weather at the present time. The icon will change to indicate an estimate
of what the weather will be like for the next 6-hours.

NOTE:

Do not randomly adjust the barometric pressure setting of the

watch. Inaccurate setting of the barometric pressure may result in
inaccurate altimeter and weather readings. If you are not certain of the
proper use of this function, it is better to leave this variable at its factory
setting. The Mean Sea Level barometric pressure may be adjusted if
desired to achieve the highest levels of accuracy.

SETTING ALTIMETER

Because the altimeter system in the ALTIS relies on Barometric Pressure for its
measurements, it is critical that you regularly calibrate the unit to a known altitude. For
maximum accuracy, daily calibration is a must. If you are using the unit during times
of changeable weather, the unit may need to be calibrated more often. Generally, the
small pressure changes experienced during a day of use will have only a minor effect on
the accuracy of the unit, however, the arrival or departure of a weather front can change
the current weather display by several hundred feet or more.

NOTE:

In the Altimeter Setting Sequence, the variable to be adjusted will

be indicated by a flashing display. Scroll through variables to be adjusted by
Pressing the Start/Split or Stop key. Select variable for adjustment by Pressing
the Mode key. Once the variable is set, Press the Mode key to return to the
Altimeter main setting sequence. You may exit the Setting Sequence any time by
Pressing the Set key.

The ALTIS is equipped with 6 Altimeter sub modes. Scroll through sub modes by
pressing the Stop key. You may enter the Altimeter Setting Sequence from any sub
mode except the TEMP/Altitude/TIME display. (See page 29 "Operating the Watch" for
a detailed explanation of submodes.)
