Casio 3017 User Manual

6

• The watch is designed to update the date and day of the week automatically for the

period January 1, 2000 to December 31, 2099. Setting of the date by a time
calibration signal cannot be performed starting from January 1, 2100.

• This watch can receive signals that differentiate between leap years and non-leap

years.

• Though this watch is designed to receive both time data (hour, minutes, seconds)

and date data (year, month, day), certain signal conditions can limit reception to time
data only.

• Normally, the signal reception date shown by the Last Signal screen is the date data

included in the received time calibration signal. When only time data is received,
however, the Last Signal screen shows the date as kept in the Timekeeping Mode at
the time of signal reception.

• If you are in an area where proper time calibration signal reception is impossible, the

watch keeps time within ±15 seconds a month at normal temperature.

• If you have problems with proper time calibration signal reception or if the time

setting is wrong after signal reception, check your current city code, DST (summer
time), and auto receive settings. The following are the initial factory defaults for these
settings.

Transmitters
This watch is designed to receive the time calibration signal transmitted from
Mainflingen, Germany and the signal from Rugby, England. You can configure the
watch to automatically select the transmitter that has the strongest signal.

The first signal auto search operation
after factory default settings are in effect,
or after the city code has been changed
Any case other than the above.

1. Checks the Mainflingen signal first.
2. If the Mainflingen signal cannot be

received, checks the Rugby signal.

1. Checks the last successfully received

signal first.

2. If the last successfully received signal

cannot be received, checks the other
signal.

• Resetting the seconds to 00

 

while the current count is in the range of 30 to 59

causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00

 

without changing the minutes.

• The day of the week is displayed automatically in accordance with the date (year,

month, and day) settings.

• The year can be set in the range of 2000 to 2099.

• The watch’s built-in full automatic calendar makes allowances for different month

lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced or when battery power drops to
Level 5.

• The times for the Timekeeping Mode and all the city codes of the World Time Mode

are calculated in accordance with each city’s UTC differential.

• The UTC differential is a value that indicates the time difference between a

reference point in Greenwich, England and the time zone where a city is located.

• The letters “UTC” is the abbreviation for “Universal Time Coordinated”, which is the

world-wide scientific standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the
Earth’fs rotation.

12-hour/24-hour Timekeeping  Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.

• With the 12-hour format, the PM indicator (P) appears on the display for times in the

range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.

• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without

any indicator.

Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after very long

use.

• Illumination may be hard to see when viewed under direct sunlight.

• The watch may emit an audible sound whenever the display is illuminated. This is

due to vibration of the EL panel used for illumination, and does not indicate
malfunction.

• Illumination turns off automatically whenever an alarm sounds.

• Frequent use of illumination runs down the battery.
Auto light switch precautions

• The auto light switch is turned off automatically whenever battery power is at Level

4.

• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of

your arm can cause frequent activation of the auto light switch and illumination of the
display. To avoid running down the battery, turn off the auto light switch whenever
engaging in activities that might cause frequent illumination.

• Note that wearing the watch under your sleeve while the auto light switch is turned

on can cause frequent illumination of the display and can run down the battery.

• Illumination may not turn on if the face of the watch is

more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.

• Illumination turns off after the preset illumination

duration (see “To set the time and date”), even if you
keep the watch pointed towards your face.

• Static electricity or magnetic force can interfere with

proper operation of the auto light switch. If illumination
does not turn on, try moving the watch back to the
starting position (parallel with the ground) and then tilt it
back towards you again. If this does not work, drop your
arm all the way down so it hangs at your side, and then
bring it back up again.

• Under certain conditions, illumination may not turn on until about one second after

you turn the face of the watch towards you. This does not necessarily indicate
malfunction of the auto light switch.

• You may notice a very faint clicking sound coming from the watch when it is shaken

back and forth. This sound is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.
