television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
FCC Caution:

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.
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 can be charged by the main
battery or the power adapter, and takes approximately 4 hours to charge to full under
the condition that it is always be charged except of power off and no external power.
RTC battery: RTC battery is a 3V, 1mAh rechargeable SMT type Li-battery which takes
about 12 hours to be fully charged. RTC retention will be maintained for at least 72
hours when the main battery is removed.
The allowed battery charging ambient temperature is between 0 to 40 . It is
recommended to charge the battery at room temperature (18 to 25 ) for optimal
performance.
Please note that battery charging stops when ambient temperature drops below 0 or
exceeds 40 .
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
pack from the mobile computer’s battery compartment. Store the mobile computer and
battery pack separately.
Recycle batteries in a proper way for the green-environment issue.

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.

RF Exposure Information (SAR)
This device meets the government’s requirements for exposure to radio waves. This
device is designed and manufactured not to exceed the emission limits for exposure to
radio frequency (RF) energy set by the Federal Communications Commission of the U.S.
Government.
The exposure standard employs a unit of measurement known as the Specific Absorption
Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. Tests for SAR are conducted
using standard operating positions accepted by the FCC with the EUT transmitting at the
specified power level in different channels.
The FCC has granted an Equipment Authorization for this device with all reported SAR
levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information
on this device is on file with the FCC and can be found under the Display Grant section
of www.fcc.gov/eot/ea/fccid after searching on FCC ID: Q3N-RS35
Radio Frequency (RF) Exposure Information
The radiated output power of the Wireless Device is below the Innovation, Science and
Economic Development Canada (ISED) radio frequency exposure limits. The Wireless
Device should be used in such a manner such that the potential for human contact
during normal operation is minimized.
This device has been evaluated for and shown compliant with the ISED Specific
Absorption Rate (“SAR”) limits when operated in portable exposure conditions.
Informations concernant l'exposition aux fréquences radio (RF)
La puissance de sortie rayonnée du dispositif sans fil est inférieure aux limites
d'exposition aux radiofréquences d'Innovation, Sciences et Développement économique
Canada (ISED). Le dispositif sans fil doit être utilisé de manière à minimiser le potentiel
de contact humain pendant le fonctionnement normal.
Cet appareil a été évalué et montré conforme aux limites de DAS (Débit d'Absorption
Spécifique) de l'ISED lorsqu'il est utilisé dans des conditions d'exposition portables.
