MAINTENANCE AND DISPOSAL
• The watch is water resistant but it is not recommended to make
any watch setting while exposed to excessive water or under
water. Pressing the keys while in the water or during heavy
rainstorms may cause water to enter into the unit.
• Batteries can be harmful if not disposed properly. Protect the
environment by taking exhausted batteries to authorized disposal
stations.
• Do not clean the unit with alcohol containing detergents, abrasive
or corrosive materials. Abrasive cleaning agents may scratch the
plastic parts and corrode the electronic circuit.
• Do not expose the unit to excessive force, shock, dust and
temperature or humidity. Such treatment may result in
malfunction, shorter electronic life span, damaged batteries, or
distorted parts.
• Do not tamper with the unit’s internal components. Doing so
will terminate the unit’s warranty and may cause damage. The
unit contains no user-serviceable parts.

TROUBLE SHOOTING GUIDE
Different altitude was
found for same
location in different
days.
This is caused by the
pressure changes due to
the activities instead of
the actual sea level
pressure change.
Recalibrate the altitude
by setting the sea level
pressure.
The bar graph of the
altitude was kept at a
high level.
The altitude exceeds the
upper limit of the
display range of the bar
graph.
The display range will
be readjusted for the
next update.
No bar graph was
observed within the
altitude mode.
(1) Battery has been
changed.
(2) The watch has been
reset.
(3) The altitude inferior
to the lower limit of
the display range of
the bar graph.
(1-2) Leave the watch
for one minute
and the altitude
record will start to
update again.
(3) The display range
will be readjusted
for the next update.
The sea level
pressure or the
altitude does not
reflect the actual
value.
(1) The watch has been
kept in a
pressurized
environment for a
period of time.
(2) This is caused by
the pressure
changes due to the
activities instead of
the actual sea level
pressure change.
Re-calibrate the sea
level pressure and
altitude .
