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

— 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 fi rst 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).
