Citizen Eco-Drive b740 Instruction Manual page 12

WARNING
• Avoid quick ascending, otherwise you may suffer from submarine sickness or a
functional disorder in some way. Whenever you ascend in water, carefully keep a
safe speed.
• Do not disturb any push buttons or the crown except button (B) (for displaying the
memorized maximum depth) throughout the dive, otherwise the watch may fail in
water-resistance.
• If the watch does not operate correctly in the water, start ascending to the surface
immediately. Start your ascent immediately, but be sure to stay below an ascent
rate of 9 m (30 ft)/min.
WARNING
• After confirming that the crown is screwed down tightly, wash out seawater, mud,
sand, etc. sticking to the watch, with fresh water. Then, wipe off water and
moisture with a dry soft cloth.
• Remove any debris or dirt that has become trapped in the sensor. If the sensor
part is packed with dust, etc., wash it out with fresh water. Neither remove the
sensor cover nor pick at it with a sharp-point in order to remove particles of dust,
etc. collected in the sensor. In addition, do not blow highly compressed air onto the
pressure sensor with an air gun. In case it is difficult to wash out dust, consult the
Citizen Service Center.
