Maintenance
If the device is not used for a long time, power it off, and then remove all the cables
connected to it.
If any exception occurs, for example, if the device emits any smoke or unusual
sound or smell, stop using the device immediately, power it off, remove all the
cables connected to it, and then contact an authorized service center.
If the device screen is broken by colliding with hard objects, do not touch or try to
remove the broken part. In this case, stop using the device immediately, and then
contact an authorized service center in time.
Do not trample, pull, or overbend any cable. Otherwise, the cable may get damaged,
causing malfunction of the device.
Before cleaning the device, stop using it, power it off, and then remove all the
cables connected to it.
Use a clean, soft, and dry cloth to clean the device shell. Do not use any cleaning
agent or spray to clean the device shell.
Certification Information (SAR)
This device meets guidelines for exposure to radio waves.
Your device is a low-power radio transmitter and receiver. As recommended by
international guidelines, the device is designed not to exceed the limits for exposure to
radio waves. These guidelines were developed by the independent scientific organization
International Commission on Non-Ionizing Radiation Protection (ICNIRP) and include
safety measures designed to ensure safety for all users, regardless of age and health.
The Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio
frequency energy absorbed by the body when using a device. The SAR value is
determined at the highest certified power level in laboratory conditions, but the actual SAR
level of the device when being operated can be well below the value. This is because the
device is designed to use the minimum power required to reach the network.
