TROUBLESHOOTING
Problem Possible cause Solution
The watch gains/loses occasionally. The accuracy will be corrected when the watch returns to normal
temperature. Set the time before using the watch. It is so adjusted
that it operates with stable accuracy when used on the wrist within
a temperature range between 5° C and 35° C (41° F and 95° F).
The watch was left in low or high
temperatures.
The display became blank. The battery has run down. Take the watch to the retailer from whom it was purchased
immediately for battery replacement.
**
The battery life indicator is shown.
The battery life indicator is flashing.
The battery is nearing its end.
A blur inside the glass persists.
Consult the retailer from whom it was purchased.
The gasket is deteriorated, and water
got inside the watch.
Unless you are at an altitude over 6,000
m (19,700 ft), the pressure sensor is out
of order.
Three altitude rank indicator bars are
flashing.
The number of residual nitrogen
indicator bars on the display
increased while on the surface.
You moved to a higher altitude across
the altitude ranks.
The watch senses the atmospheric pressure change and re-
calculates residual nitrogen. The obtained residual nitrogen will be
taken into consideration in calculations in the dive plan function.
The atmospheric pressure inside
airplanes corresponds to altitude rank
“2”, and the watch has re-calculated
the altitude.
The number of residual nitrogen
indicator bars on the display
increased during flight.
Water remains on the auto switch.
The display will not return to the
TIME/CALENDAR after diving.
Wipe the auto switch with a dry cloth.
Water remains on the auto switch, or
the auto switch was turned on during
flight and the airplane landed.
The dive function was shown while
on the surface, and a depth of more
than 1.5 m (5 ft) was displayed.
Make sure that the auto switch is always clean and dry. In a place
such as inside an airplane where the atmospheric pressure changes
sharply, take utmost care not to leave the auto switch wet.
A dive beyond the specified limit was
made within the past 48 hours.
The dive function will not start.
Do not use the watch for diving for 48 hours.
The battery life indicator is lighting up or
flashing.
Take the watch to the retailer from whom it was purchased
immediately for battery replacement.
Three altitude rank indicator bars are
flashing.
The watch cannot be used for diving at an altitude over 6,000 m
(19,700 ft). Unless you are at an altitude over 6,000 m, the
pressure sensor is out of order. Consult the retailer from whom
it was purchased.
