SIM Card Overheating
It's normal for SIM card to heat up during operation. Some SIM cards may
even get very hot after using for long time. Therefore, touching the SIM card
and it is best to wait until the SIM card is cooled down.
Mobile Phones
Using mobile phone may affect the sound system of the tablet PC.
Although this does not affect its operation, we still recommend you to keep the
distance between the phone and the tablet PC at least 30cm.
CPU Performance
Due to inherent design of Intel Mobile CPU, its performance can vary due
to
External devices may require additional CPU resources and slow down the
system performance
- Depending on the power option profile, X11 usually runs faster when it is
connected to AC adapter than when it is operating only on battery power
- The number of concurrently running applications
- The performance may be reduced in area with low atmospheric pressure
(elevation higher than 1000m/3280feet)
- System temperature, the higher then system temperature, the lower the
processor performance.
Under low pressure or high/low temperature, X11 may automatically
shutdown to protect system. Automatic shutdown function reduces the risk of
data loss or damage to the device. To avoid data loss, please backup your
data to your external storage regularly. For best performance, please use your
X11 within normal operation parameters listed in the specification section.
Working environment
Working in a suitable environment is very important for both you and your
X11. Unsuitable working environment can increase stress, chance of injuries
and damages to your X11.
X11 is designed to fit with today's mobile work demand and lifestyle. To
use X11 without any auxiliary support besides hands and arms, we
recommend placing X11 on one arm and holder the edge of X11 with hand of
the supporting arm. This creates the best balance and allows extended use
with less fatigue.
For using X11 on a table or any surface, it is recommended to place X11
on a flat and smooth surface without block the ventilation holes underneath
X11.
Operating temperature: 32° to 104° F (0° to 40° C)
Storage temperature: 14° to 140° F (-10° to 60° C)
