SAFETY PRECAUTIONS
Warning statement:
A pleine puissance, l’écoute prolongée du baladeur peut endommager
l’oreille de l’utilisateur.
To prevent possible hearing damage, do not listen at high volume levels
for long periods.
.
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE
OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
For people’s safety
Do not listen at high volume levels for long periods to prevent possible hearing damage.
Do not operate this device while walking, cycling or car driving.
For the equipment
Do not use any batteries or charging devices which are not originally sold or
manufactured by CIPHERLAB CO., LTD.
Do not replace the battery with an incorrect type, to avoid the risk of heat generation,
fire, or explosion.
Do not disassemble, incinerate or short circuit the battery.
Do not touch the contact pins of the battery pack.
Do not expose the mobile computer or battery to any flammable sources.
Do not expose the mobile computer to extreme temperatures or soak it in water.
Do not use any pointed or sharp objects against the screen surface.
Do not use the styluses which are not supplied or approved by CIPHERLAB CO., LTD., to
prevent possible scratches to the touch screen.
Water residue on the touch screen may cause abnormal behaviors or the fall of its
sensitivity levels.
On the surface of the terminal and the barcode reading window, the fog or water drops
caused by low temperatures may influence barcode reading.
Do not use bleaches or cleaners to clean the device. Use a clean, wet cloth instead.
BATTERY
The main battery may not be charged to full for shipment. Charge the main battery to full
before using the mobile computer for the first time.
Main battery: The main battery powers the mobile computer to work. It takes
approximately 4 hours to charge an empty main battery to full. For the first time
charging the main battery, please charge it for at least 8 to 12 hours. The charging LED
above the screen will light up in red while charging and will turn green when charging is
complete.
When the main battery is removed, RTC retention will be maintained for at least 30
minutes.
Backup battery: The backup battery is mounted on the main board. Its role is to
temporarily keep the mobile computer in suspension when the main battery is drained
out so data in DRAM will be retained. The backup battery takes approximately 3.5 hours
to charge to full by the main battery or power adapter.

RK25 Mobile Computer
The allowed battery charging ambient temperature is between 0°C to 40°C. It is
recommended to charge the battery at room temperature (18°C to 25°C) for optimal
performance.
Please note that battery charging stops when ambient temperature drops below 0°C or
exceeds 40°C.
In order to prevent system from shutting down after the battery is drained out, keep a
fresh battery for replacement at all times, or connect the mobile computer to an external
power.
If there are drippings or dust on the device or battery pack, wipe them away with a soft
clean cloth before battery replacement.
Turn off the power before battery replacement.
If you want to put away the mobile computer for a period of time, remove the battery

Important Notices
CONNECTION
Via Bluetooth or WLAN
Connection may fail when the mobile computer is around other wireless machines or
power cables as the radio frequencies of those may cause interferences.
If communication fails, move the devices much closer to each other, and try to
communicate again
After turning on, Bluetooth power is sustained even when the mobile computer is
suspended. However, if the power mode is switched to Airplane Mode, Bluetooth power
will be turned off regardless of the settings.
To a Charging & Communication Cradle
Do not insert the mobile computer to a Charging & Communication Cradle if water or
drippings are staying on the device.
The LED indicator on a Charging & Communication Cradle shows the status of battery
charging only; the status of terminal charging is shown on the device itself.
Not Charging could be the result of battery damage, battery’s failure to touch the
connector or AC plug coming off.
Charging error could be due to high battery temperature.
CARE & MAINTENANCE
This mobile computer is intended for industrial use. The mobile computer is rated IP67,
however, damage may be done to the mobile computer if it is exposed to extreme
temperatures or soaked in water.
When the body of the mobile computer gets dirty, use a clean, wet cloth to wipe off dust
and debris. DO NOT use bleaches or cleaners.
Use a clean, non-abrasive, lint-free cloth to wipe dust off the LCD touch screen. DO NOT
use any pointed or sharp objects against the surface. Always keep the LCD dry.
If you want to put away the mobile computer for a period of time, download the collected
data to a host computer, and then remove the battery pack from the mobile computer’s
