Important Safety Instructions
Read these safety instructions carefully:
► Read all cautions and warnings on the equipment.
► Place this equipment on a reliable surface when installing. Dropping it or
letting it fall may cause damage.
► Make sure the correct voltage is connected to the equipment.
► For pluggable equipment, the socket outlet should be near the equipment
and should be easily accessible.
► Keep this equipment away from humidity.
► Disconnect this equipment from the A/C outlet before cleaning it. Use a
moist cloth. Do not use liquid or sprayed detergent for cleaning.
► Do not scratch or rub the screen with a hard object.
► Never use any of the solvents, such as Thinner Spray-type cleaner, Wax,
Benzene, Abrasive cleaner, Acid or Alkaline solvent, on the display. Harsh
chemicals may cause damage to the cabinet and the touch sensor.
► Remove the dirt with a lightly moistened cloth and a mild solvent detergent.

Then wipe the cabinet with a soft dry cloth.
► If the equipment will not be used for a long time, disconnect it from the
power source to avoid damage by transient over voltage.
► Never pour any liquid into openings. This may cause fire or electrical
shock.
► If one of the following situations arises, get the equipment checked by ser-
vice personnel:
a. The power cord or plug is damaged.
b. Liquid has penetrated into the equipment.
c. The equipment has been exposed to moisture.
d. The equipment does not work well, or you cannot get it to work according
to the user’s manual.
e. The equipment has been dropped or damaged.
f. The equipment has obvious signs of breakage.
Rechargeable Battery Pack Safety
With very little care, you can optimize the battery life and maximize the
lifespan of the battery. Most importantly, use only the equipment in its ideal
operating temperature (as described in 1.4 Specifications) – do not leave it in
a hot trunk during the summer.
•Using the Equipment for the First Time
Be sure to fully charge (approx. 4 hours) the equipment when charging the
equipment for the first time.
•Long-Term Storage & Maintenance
If you are putting away the battery for more than three months, it is recom-
mended that the battery should be stored separately and fully charged,
and get recharged every three months. If you store an uncharged battery,
it could fall into a deep worn-out state which would render it incapable of
holding any charge. Be sure to store the equipment and battery at the
proper temperature (as described in 1.5 Specifications).

Chapter 2: Getting Started
2.1 Power On/Off and Sleep/Wake
This Chapter is describing how to power on/off the device, put the device into
sleep mode (screen saver) and force restart.
Proper operation of power on/off the device will be beneficial to ensure the stability
of the system. The device status indicated by the color of the indicator is as de-
scribed in the following table for the standard VT-7 Pro. We provide customized
service if the customer has other requirements regarding the operation of switch.

The device is abnormal, please cut off the external power
supply immediately and return it back to the factory for re-
pair.
2.1.1 Power on the Device
1. Power on by pressing the button:
Long press the power button for more than 2 seconds until the boot screen dis-
played. It needs around 40 seconds to start the system. The indicator is on
when VT-7 Pro activate normally.
2. Power on by connecting ACC, see the details in Chapter “3.3 Using ACC”.
3. Power consumption during operation：5w (typical)
2.1.2 Power off the Device
1. Power off by pressing the button: In the status of working on the device desk-
top, long press the power button for more than 2 seconds until the shutdown
prompt pop-up then click the “POWER OFF” option.
2. Power off by ACC, see the details in the Chapter “3.3 Using ACC”.
3. Remark: In order to reduce the standby power consumption, the red light is on
in charging status when power on. And the light will go off if full charged.
4. The consumption during power off (with docking station): around 100mW.
2.1.3 Sleep and Wake the Device
a. Auto sleep, the sleep time can be set up in the settings.
b. Short press button to sleep.
c. Sleep by ACC, see the details in Chapter “3.3 Using ACC”

d. Short press to wake
e. Wake by ACC, see the details in Chapter “3.3 Using ACC”
f. The average of power consumption in sleep status: 1W
2.2 Installing Micro SD and SIM Card
To install the micro SD card and/or Micro SIM card:（Note：Must be installed in
power off status!）
a. Find the Micro SIM card slot and the Micro SD card slot. The following
graphics illustrates the correct cards orientation, which the card chips is facing
into the display orientation:
b. To install the Micro SIM card(s) or the Micro SD card, orient the card as indi-
cated, and fully insert the card into the slot until it locks into place.
c. Lock the interface cover with screws.
2.3 Charging the Battery
The battery is partially drained during the transportation. Be sure to charge the bat-
tery to full when you are charging it for the first time.
Tips:
Please keep the DC in charging status at work if available. Owe to the unique
power supply design (Patent No.: CN201821205954.6), the device using the
power supplied by DC input or USB type-C input in priority, rather than the power
from the internal battery. It makes the battery to be stored after fully charged. This
excellent design is very beneficial for extending the life of the VT-7 Pro battery and
ensuring the safety in use.
In order to ensure the life and performance of the battery, if your tablet has been
stored in the warehouse for more than three months, it is recommended to charge
the battery every three months.

2.3.1 Charging with the Power Adapter
To charge the battery with the provided power adapter:
a. If the device with an optional docking station, then mount the VT-7 Pro tablet
with docking station, connect the power adapter to the DC port of Docking Sta-
tion.
b. The VT-7 Pro could be charged by a 5V 2A or above by USB type-C cable.
Warning:
Please ensure that the input voltage of the DC interface is within the range of 8V-
36V, or use the 12V adapter coming with device. If the input voltage of the DC is
outside this range, the VT-7 Pro may be unable to charge or damaged. It may
cause the warranty invalid.
2.3.2 Checking the Battery Level
a. When the charging is in process, a battery indicator will appear in the status bar
showing the charging percentage. To view the charge percentage, swipe down the
Status Bar and you will see the charging percentage.

b. When the battery is fully charged, you can disconnect the DC input or USB
type-c cable. If available, please keep the device in charging by DC power supply.
See the details in “2.3 Charging the Battery”.
2.3.3 Installing/Replacing the Battery
In case you need to install or replace the battery, follow the steps below to access
the battery chamber and replace the battery.
1. Place the device on a flat surface, with the rear side facing up. Loosen the re-
taining screws on the back cover by using a Hexagon socket screwdriver with
flat head.

2. To install a new battery, orient the new battery so that the contact pins are
aligned correctly.
3. Assemble the battery cover and secure the retaining screws by using a Hexa-
gon socket screwdriver with flat head.
2.4 Optimizing Battery Life
If the VT-7 Pro is unable to keep charging by DC power supply, to optimize the op-
erating time of the battery, it is recommended that you do the following:
➢Decrease the LCD display brightness.
➢Set a shorter timeout of inactivity to allow the screen enter sleep mode.
➢Turn off the display if you are not using it.
➢Turn off Wi-Fi, Bluetooth or GPS function if you are not using it.
➢Turn off the App that heavily drains the battery if you are not using it. To view
the battery usage by individual App, swipe down the Status Bar in the upper
right corner and tap and hold the Battery icon.

➢Enable CPU power saving mode on battery settings page to limit the maxi-
mum CPU performance to conserve battery life and lower device tempera-
ture.
To access the battery settings page, swipe down the Status Bar in the up-
per right corner and then tap and hold the Battery icon.
