S.The battery warning function and the battery
1. Battery warning function
• This watch has a battery warning function to let
you know when to charge the battery.
• When the dot display alternates between “BAT.,”
(D201/D207)/”BT’’ (D202/D208) and dot display,
this indicates that the battery is low. Please take
the watch to a Citizen Service Centre to get the
battery changed and the watch checked as soon
as possible.
★Caution:
When the battery warning function
appears during normal display
modes, except diving mode, you can
not change to diving mode. In diving
mode after the battery warning
function appears, the battery warning
function may disappear when you cancel diving
mode. However, the battery is still low and
requires changing as soon as possible.
2. Battery
a. Under the following usage
• Under the following usage condition, the life span
of the battery is three years, after a new battery is
installed. Usage conditions;
1) Number of dives: 100 per year
2) Dive time: 35 mins. (per dive)
3) Data transfer: Once a week
The life span of the battery may change
depending on the frequency each function is
used. (Alarm, Lamp, Diving mode, etc.)
When using the watch for purposes other than
diving, the battery life will be shortened according
to the length of time the water sensor is wet.
★Depending on the amount of dives, the probable
battery life span is as follows.
35 mins. 200 times per year: 2.2 years
35 mins. 300 times per year: 1.8 years
b. The first battery
• The battery which is already in your watch when
you purchased it, is a monitor battery used to
check the functions of the watch, and so the
battery may require changing within 2 years after
purchasing the watch.
c. Changing the battery
1) When the battery is changed, the water
resistance should be checked, and if need be the
seals changed. So it should be carried out by the
manufacturer as a repair. Please arrange for a
Citizen Service Centre to look after your watch
through the shop you purchased it from.
2) When changing the battery, the log data and
profile data will be lost, so please transfer the
data to a personal computer or record it in a log
book beforehand.
3) If you leave a dead battery inside the watch,
leakage can cause damage, so we recommend
that you change the battery as soon as possible.
4) If you intend to use the watch overseas for any
length of time, there may be a chance you cannot
get the watch serviced, so we recommend you
change the battery prior to your departure.
5) The changing of the battery, and the checking
and changing of any incidentals, even within the
guarantee period, will be chargeable.
T.For long usage
1.Water-resistance
a. In order to ensure that your watch stays water-
resistant, you should have it inspected once every
one or two years in addition to regular battery
replacement.
2. About the depth sensor (Pressure sensor)
a. There is a sensor cover that protects the
sensor area of your depth meter. Never remove it.
b. Be careful not to get any sand, particles, dust,
etc. on the sensor area. If this happens, rinse the
watch with alcohol or chemicals such as gasoline,
thinners, etc.
c. If you cannot adequately clean your watch,
please consult your nearest Citizen Service Centre.
