Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your

purchase, be sure to read this manual carefully.

• This watch does not have a city code that corresponds to the UTC offset of –3.5

hours. Because of this, the radio-controlled atomic timekeeping function will not

display the correct time for Newfoundland, Canada.

E E-1

Keep the watch exposed to bright light

The electricity generated by the solar cell of the watch is

stored by a rechargeable battery. Leaving or using the

watch where it is not exposed to light causes the battery

to run down. Make sure the watch is exposed to light as

much as possible.

• When you are not wearing the watch on your wrist,

position the face so it is pointed at a source of bright

light.

• You should try to keep the watch outside of your sleeve

as much as possible. Charging is reduced significantly if

the face is covered only partially.

Battery charges in the light. Battery discharges in the dark.

• The watch continues to operate, even when it is not exposed to light. Leaving the

watch in the dark can cause the battery to run down, which will result in some watch

functions to be disabled. If the battery goes dead, you will have to re-configure watch

settings after recharging. To ensure normal watch operation, be sure to keep it

exposed to light as much as possible.

E-3

• The actual level at which some functions are disabled depends on the watch model.

• Frequent display illumination can run down the battery quickly and require charging.

The following guidelines give an idea of the charging time required to recover from a

single illumination operation.

Approximately 5 minutes exposure to bright sunlight coming in through a window

Approximately about 8 hours exposure to indoor fluorescent lighting

• Be sure to read “Power Supply” (page E-45) for important information you

need to know when exposing the watch to bright light.

If the display of the watch is blank...

If the display of the watch is blank, it means that the watch’s Power Saving function

has turned off the display to conserve power.

• See “Power Saving Function” (page E-69) for more information.

The watch has been in a safe for at least 6 months and will have gone into sleep mode. I retrieved the watch but the hands are at the 12 o’clock position. I have pressed the buttons but there is no response. ‘ Have placed the watch in a bright spot in the house but this has failed to bring about watch back to life. I suspect it’s the battery. Do you have any troubleshooting advice? Thanks

What is a quartz movement? Verified

Watches and clocks with a quartz movement are driven by a battery. This sends an electric current through quartz crystals that will vibrate. These vibrations are passed on to the movement. Because the vibrations have a fixed frequency, watches and clocks with a quartz movement are extremely precise.

There is moisture on the inside of the glass of my Casio watch, what should I do? Verified

Casio states that if the moisture appeared after an extreme change in temperature and disappears relatively quickly afterwards, there is probably nothing wrong. If the moisture does not disappear, you should have your watch repaired as soon as possible.
