Operating Precautions
Your terminal and its options are precision. Improper operation or rough handling can cause
problems with data storage and other problems. Note and observe the following precautions
to ensure proper operation.
• Do not continue using the battery once it is exhausted.
Doing so could result in data loss or corruption. When the battery is exhausted, replace it
immediately.
• Stop or avoid using the terminal and its options in areas and conditions subject to
the following.
— Large amounts of static electricity
— Extreme heat or cold or humidity
— Sudden temperature change
— Large amount of dust
— After large amount of rain or water falls on the terminal
— Pressing the screen or keys with excessive force when using in the rain
• Always use the dedicated eject pin to eject the nanoSIM/microSD card tray.
• Do not use volatile chemical substances such as thinners, benzene or toiletries to
clean the terminal.
When the terminal is dirty, wipe it clean with a soft, dry cloth. Rubbing with excessive
force could scratch the display.
• The power-supply terminals should be cleaned periodically using an implement such
as a dry cotton bud.
Soiling on the terminals may cause connection defects.
• Take care when using chemicals.
Applying thinners, gasoline, kerosene, solvents or oils, or substances such as cleaners,
adhesives, paints, medications or toiletries that contain those materials, to the plastic case
or cover may cause discoloration or other damage.
• LCD panel
The following are characteristics of the LCD panel and do not indicate a fault.
— The LCD panel is manufactured using high-precision technology and features a
minimum of 99.99% effective pixels. There may be some pixels that fail to light or that
remain permanently lit.
— If the same screen is displayed on the panel for a prolonged period, its afterimage may
persist after a new screen is displayed. The afterimage will fade after a few moments.
• 802.11a/n Restrictions
— This product is for indoor use only when using channels 36, 40, 44, 48, 52, 56, 60, or
64 (5150-5350 MHz).
— To ensure compliance with local regulations, be sure to select the country in which the
access point is installed.
• Do not use a strap other than the one supplied.
• Built-in battery
The terminal’s battery is built into the terminal and cannot be removed.
The built-in battery has a limited service life. The way the built-in battery is charged can
accelerate its degradation or reduce its capacity so that it cannot be used for as long. If
charging the built-in battery does not restore its full functionality, this indicates that it has
reached the end of its life. If this occurs, request a replacement.
Using the correct charging procedures will maximize the service life of the built-in
battery.
— You should charge the built-in battery fully the first time you use it and whenever it has
not been used for a long period. Continue charging until the charging status LED lights
green (fully charged).

9
— Frequent repeated charging will shorten the life of the battery. You should wait until
the battery is low on charge before charging it.
— Charge the battery within the specified temperature range. Note that the specified
temperature range varies depending on the equipment used. Refer to the User's Guide
(download version). Charging outside the specified range can cause battery
deterioration.
— When used in low-temperature environments, the built-in battery capacity may be
lower so that it cannot be used for as long. It may also shorten the life of the built-in
battery.
— Charging when the terminal is cold can cause built-in battery deterioration. After
working in a cold environment, allow the terminal to warm up to room temperature
(leave for roughly 1 hour) before charging.
— For long-term storage, do not store the built-in battery fully charged. The battery
should be 30-50% charged for long-term storage and it should be stored at a low
temperature. This will minimize battery deterioration.
Note also that even when not being used, the built-in battery will gradually discharge.
If this situation continues for a long period (several months or more), the built-in
battery will become overdischarged, which may impair quality and performance.
— Rechargeable batteries will deteriorate over time. Storing (or using) fully charged
batteries at high temperatures in particular can lead to faster deterioration.
• Drop resistance
The drop resistance is a test value only and is not guaranteed.
Repeated or frequent shocks may still result in damage, so the terminal should be handled
so as to avoid impacts.
• Water or other moisture on the power-supply terminals could cause sparking or an
electric shock, and soiled contacts could block the connection and impair charging
functionality.
• While the ET-L10 is waterproofed, note the following when using this product:
• If the ET-L10 is exposed to water droplets, thoroughly wipe off the moisture with a dry
cloth.
• Do not use the ET-L10 for long periods in the rain.
• Securely close the connector covers when using the ET-L10.
• Do not press hard on the screen (touch panel) or keys when using the ET-L10 in the rain.
• The back of the ET-L10 may become warm during use. This is normal and does not
indicate a fault.
• Weld Lines
There are seam-like markings in some locations on the terminal. These are
referred to as “weld lines” in the plastic forming process and are not cracks or scratches.
Weld lines do not interfere in any way with the operation of the terminal.
• Limited-life parts
This product includes limited-life parts (memory, LCD panel, etc.).
The approximate period for which limited-life parts can be used differs according to the
frequency of use and other conditions. However, in normal use, this period is roughly
3 years assuming the product is used for roughly 8 hours per day.
The above period is intended solely as a general guide and in no way guarantees that the
parts will not develop a fault or will be repaired at no cost within that period.
Note also that in some types of use, such as extended continuous use, the parts may need
to be replaced (at a fee) sooner or within the product warranty period.

10
• Repairs to terminals configured with a Google account
If a terminal needing repairs has been configured with a Google account, delete the
Google account settings before sending the terminal to be repaired.
During repairs, Casio resets the terminal to the factory default status. However, terminals
with a Google account are equipped with the Google device protection function, which
prevents unauthorized use in the event that it is lost or stolen. To reset a terminal
configured with a Google account to the factory default status, the Google account
credentials must be entered. For this reason, the user must delete the Google account
settings registered in the terminal.
Refer to the following website for information on how to delete the Google account
settings:
