Operating Precautions

The projector’s light source unit uses a laser and LED.

The life of the light source unit is rated at approximately 20,000 hours. The actual life will depend on

use conditions, the settings configured on the setup menu, and differences between each individual

light source unit.

The light source unit is warranted for the period noted on the warranty certificate or for 6,000 hours,

whichever comes first.

The failure of the light source unit to light or a noticeable drop in light source unit brightness

indicates the end of the light source unit’s life. Contact your original dealer or authorized CASIO

service center for replacement. Note that problems caused by unauthorized projector disassembly

or modification are not covered by the warranty and are not eligible for repair by CASIO.

About the Light Source Unit

Do not block light output or look directly into the

lens!

Never block light output while the light is on.

Never look directly into the lens while the light is on. Particular care is

required when children are present.

Charging Precautions

Charge a battery in a location whose ambient temperature is between 10°C and 30°C (50°F to

86°F).

Charging may take longer, or full charging may not be possible under temperatures outside of this

range.

Charging may not be possible if the ambient temperature and battery temperature is too high or too

low. If this happens, remove the AC adapter from the battery and place the battery in a location

whose ambient temperature is between 10°C and 30°C (50°F to 86°F) for a while, and then try

charging in that location.

A battery that has not been charged for a very long time (about six months) may take longer than

usual to charge. Charging will stop automatically if a battery has not become fully charged after

about six hours of charging.

Precautions When Using a Battery

Due to battery characteristics, a charged battery will provide less operating time under cold

temperatures than it provides under normal temperatures.

Do not break or remove the outer label of a battery.

If a battery goes dead very shortly after it is charged, it probably means that the battery has reached

the end of its service life. If this happens, purchase a new battery.

Do not connect two batteries to each other.

Precautions During Battery Storage

Keep batteries out of areas subjected to high temperatures and humidity. Store them in a cool

place.

To prevent over-discharge, charge a battery to a charge level of 60-41% at least once every six

months. For details about charge levels, see “Indicator During Charging” (page 31).

You may not be able to get a battery to start charging if it has not been charged for a long time

(about six months). If this happens, contact your original retailer or a CASIO Service Center.

If a battery is not used for approximately 1.5 months, it will automatically go into a low-power mode.

A battery will not supply power while in the low-power mode. Charging the battery will exit its low-

power mode and allow it to supply power.

A battery deteriorates over time. The pace of the deterioration depends on ambient temperature

and the charge state of the battery. In particular, a fully charged battery that is left in a hot

environment tends to deteriorate more rapidly, regardless of whether it is being stored or used

there.
