Water Sensor Error; Pressure Sensor Error; When A Pressure Sensor Error Occurs While Diving; Measurement Error (0 M/0 Ft Detection) - Citizen U10 Instruction Manual

<Water Sensor Error>
A water sensor error occurs and the
alarm mark is displayed when the water
sensor remains ON for more than 60
minutes in Diving Ready 1 or Diving
Ready 2 status.
• When a water sensor error is detected,
the watch returns to the time/date
mode from the diving ready 1 or
diving ready 2 display.
<Pressure Sensor Error>
When a pressure sensor error occurs as a result of a
disconnection in the sensor caused by a strong impact or
debris, stones or moisture having become trapped inside
the sensor cover, the [ ] error mark is displayed on the
digital display.
• The watch does not switch to the diving mode while an
error mark is displayed.
When a Pressure Sensor Error Occurs While
Diving:
Water depth and temperature cannot
be measured. Data is also not
updated. In addition, the various dive
alarm tones do not sound.
• Digital display: The [ ] error mark
is displayed.
Water depth display: "--.- M" ("--- ft")
Water temperature display: "--˚C" ("--˚F")

<Measurement Error (0 m/0 ft Detection)>
Initial 0 m/0 ft detection: This refers to the value serving
as the reference water depth, and atmospheric pressure is
detected every 5 minutes when on land. The value
measured at those times is stored in memory as a 0 m
(0 ft) reference value.
• Although the initial 0 m (0 ft) value is updated after each
measurement, a value that exceeds a predetermined
value is considered to be in error and the reference value
is no longer updated.
• In the case an abnormal value has been detected, the
water sensor is judged to be in error and the [
mark is displayed in the time/date mode.
• The watch cannot be used for diving when an error mark
is displayed even if the water sensor has detected water
since the watch does not enter the diving mode.

[Canceling Abnormal Measured Value]

• The abnormal measured value is canceled when a correct
value has been detected after having detected an
abnormal value.
• When the abnormal measured value is canceled, the error
mark is no longer displayed and the water sensor begins
to operate.
