is a sensor malfunction, when battery power drops below a certain level, or
when battery voltage is decreased below a certain level due to very cold
temperatures.

• If the sensor is malfunctioning when it comes time for an barometric
pressure measurement to be taken, the barometric pressure value appears
as xxxx on the display and the corresponding point on the barometric

marks flash next to ALM, SIG and A-LIGHT whenever there is a
momentary voltage drop due to continuous use of the backlight, etc. The
marks stop flashing when voltage returns to its normal level.
• The alarm, hourly time signal, and backlight are all disabled whenever the
marks are flashing on the display.
• All functions, except for mode change operations, are disabled while the

ABOUT ALTITUDE AND AIR
PRESSURE MEASUREMENTS
Altimeter
Generally, air pressure and temperature decrease as altitude increases. This
watch bases its altitude measurements on International Standard Atmosphere
(ISA) values stipulated by the International Civil Aviation Organization (ICAO),
which define relationships between altitude, air pressure, and temperature.

There are two standard methods of expressing altitude: Absolute altitude and
relative altitude. Absolute altitude expresses an absolute height above sea
level. Relative altitude expresses the difference between the height of two
different places.
