This device complies with Part 15 of the FCC Rules. Any changes or
modifications not expressly approved by the guarantee of this device could
void the user’s authority to operate the equipment.
FCC Statement
In-Vehicle Display Terminal has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or 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.
Caution: Any changes or modifications to this device not explicitly approved by
manufacturer could void your authority to operate this equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions:
This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause
undesired operation.
Specific Absorption Rate (SAR) information:

thorough evaluation of scientific studies. The standards include a substantial

safety margin designed to assure the safety of all persons regardless of age
or health. FCC RF Exposure Information and Statement the SAR limit of USA
(FCC) is 1.6 W/kg averaged over one gram of tissue. Device types:
Communicator has also been tested against this SAR limit. This device
was tested for typical body-worn operations with the back of the phone kept
00mm from the body. To maintain compliance with FCC RF exposure
requirements, use accessories that maintain an 0mm separation distance
between the user's body and the back of the phone. The use of belt clips,
holsters and similar accessories should not contain metallic components in its
assembly. The use of accessories that do not satisfy these requirements may
not comply with FCC RF exposure requirements, and should be avoided.

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
recommended that the batteryshould 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.

2.3. Charging the Battery
The battery is partially drained during the transportation. Be sure to charge the
battery to full when you are charging it for the first time.
Tips:
Please keep the DC in charging status at work if available.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-7GA/VT-
7GE tablet with docking station, connect the power adapter to the DC port
of Docking Station.
b. The VT-7GA/VT-7GE could be powered by 5V charger adapter through a
type-C cable.
c. The DC power supply voltage input range of the docking station is 8-36V,
and the DC power supply of the tablet is 5V. Please note that the adapter
must be of the corresponding specification when supplying power to the
tablet or the docking station.
Note:
1. Tablet powered via docking station
When the docking station is connected to 8~36V power supply, and the ACC

9
User’s Manual
wiring is connected to a power supply above 5~36V, the docking station can
keep supplying power to the tablet;
When the Docking station is connected to 8~36V power supply, and the
voltage of the ACC wiring drops from 5~36V to below 4V, the docking station
will continue to supply power to the tablet for one hour, and then stop supplying
power to the tablet. This is to simulate the situation that the car is turned off, to
prevent the tablet from continuing to consume a large amount of vehicle
battery power, resulting in the car not being able to ignite and start;
When the docking station is connected to 8~36V power supply, and the
connection voltage of the ACC wiring is always less than 4V, the docking
station will not supply power to the tablet;
2. Tablet powered via Type-C
The voltage requirement range is 4.75~5.25V, and a 5V/2A power adapter is
recommended.
Note:
The power supply of the docking station has priority over the Type-C power
supply. When both power sources are present, the tablet will automatically
switch to be powered by the docking station.
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.

User’s Manual
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
retaining 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
Hexagon socket screwdriver with flat head.
2.4. Optimizing Battery Life
If the VT-7GA/VT-7GE is unable to keep charging by DC power supply, to
optimize the operating 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.

11
User’s Manual
Turn off the display if you are not using it.
