3. Instructions SIM card & TF card
The SIM card, memory card and the card connectors on the device are
precision electronic components. When inserting the SIM card or
memory card into the card connectors, you much insert after aligning
to the position accurately in case of damaging the components. When
removing the SIM card or memory card, please slightly push the upper
edge of the card to loosen the card, then pull it out.
The memory card will get heat after long time working. It is a normal
phenomenon.
If you don’t use SIM card correctly, or cutting off the power or pulling
out the SIM card during the operation, the network will be interrupted
automatically.
Insert the memory card as shown in below picture
Find the location of the SIM card or memory
card slot on the unit, then push the SIM card
or Micro SD card with the part of the metal
contacts outward until it snaps into the
location.
Do not force to Insert the SIM card or memory
card to avoid damaging the card.

4-5-3 Device is equipped with batteries
a. Rechargeable batteries
Due to transportation, the battery will be partially drained when the
package is delivered to you. Make sure the battery is fully charged on
the first charge.
Please keep dc in charging state when working. The device uses a DC
input power source first, rather than a power source stored in an
internal battery.

b. Check the battery level
During charging, the status bar will display the battery power indicator,
showing the charging percentage.To see the percent charge, slide
down the status bar to see the percent charge.
When the battery is fully charged, the DC input can be disconnected. If
available, use a DC power supply to keep it charged.
c. Check the battery level
If the monitor cannot be continuously charged by dc power, to optimize
the working time of the battery, it is recommended that you do the
following
Turn down the display brightness.
Set a short time to go into sleep mode.
Turn off the monitor when not in use.
Not applicable to the application. To check the battery usage of each
application, the application can be a serious drain on the battery. Not
applicable to the application. To check the battery usage of each
application, the application can be a serious drain on the battery.
Enable CPU power saving mode on the battery Settings page to limit
the maximum CPU performance to save battery power and reduce
device temperature. To get to the battery Settings page, slide down the
status bar in the upper right corner and long press the power-saving
mode button to turn it on.
