FAQ
1. Why does fog often appear on the screen?
To ensure the safety of the screen, a layer of tempered glass is added to the external of the
screen. Moreover, to ensure heat radiation, there needs to be some gap between the two to
reserve an air passage for ease of the convection of the air. The reason why fog appears is
that there is a temperature difference between the screen temperature and the external
temperature, and the hot air condenses and generates fog due to the glass surface with lower
temperature. The fog does not affect the normal use, and it will evaporate and disappear after
the machine is used for several hours.
2. Why are the boot times of the devices in different meeting rooms are different?
Generally, the external U disk or surfing online will let the device get virus. As a result, the disk
space is fully occupied, or the system disk is damaged. Therefore, the boot of the device will
get slower.
3. Why there is no sound for the external notebook computer?
In case of the VGA wire connection where only pictures are transmitted, you need to further
connect the audio wire. Likewise, if only the audio wire is connected, the sound cannot be
produced, and you need to connect the VGA wire to identify the VGA channel, or you can
select the HDMI wire connection.
4. The attached touchpens are limited. Is there any object that can replace the touchpen for
flexible writing and at the same time does not damage the screen?
Fingers can be temporarily used for writing. In addition, if necessary, you can buy more writing
pens.
5. After used for some time, the screen is overheated. Is it normal? Will it bring any bad
influence?
It is normal that the screen is overheated, which will not bring any bad influence. Currently, the
heat radiation design of our machine is advantageous in the industry. We are the maker of the
industry standard, which complies with the international health standard.
6. Will it be harmful for eyes in case of use for a long time?
The identification of human eyes to the twinkling is 50 Hz, and the human eyes can feel the
twinkling if the frequency is below 50 Hz. The eye muscles need to continuously adjust to
adapt to the twinkling, which results in the fatigue of eyes. The frequency of the LCD we use
is 60 Hz and 120 Hz. Therefore, human eyes cannot feel the twinkling of our screen, which
can reduce the fatigue of eyes to a large extent compared with other similar products.

Simple Troubleshooting
Abnormality of Booting
I. Automatic power off
1. Is the sleep function enabled? Troubleshoot according to the general checking items of the
computer.
2. Check whether there is a signal on the channel where the input source is in. If there is no
signal, the meeting machine will automatically enable the energy saving mode to power off.
3. Check the stability of the power supply.
II. The indicator is off.
1. Check whether the power supply is normal.
2. Check whether the rocker switch of the tablet computer is turned on.
III. The indicator turns red, and booting is unavailable.
1. If pressing the button cannot turn on the IFP, unplug all the external wires, and turn on the
IFP again after cutting off the power for 15 minutes.
Abnormality of Computer Functions
I. The IFP cannot display the content of the interface of the external computer.
1. Check whether the current channel is VGA channel.
2. Check whether the VGA wire of the tablet computer or external computer is loose or poor.
II. The pictures lack colors, or the color is abnormal.
1. Check whether the VGA wire is well connected or whether it is the quality problem.
Abnormality of Sound Function
I. There are pictures but no sounds for the device.
1. Try adjusting the volume by using VOL +/-.
2. If the tablet computer is connected to the external computer, check whether the audio wire
is correctly connected.
3. If the problem still persists, please contact professional after-sale maintenance personnel
for your service.
Abnormality Touch Function
I. Inaccurate touch positioning.
1. Check whether the touchpen or the finger is 90 degrees vertical to the screen.
2. Check whether there are other objects touching the screen, for example, little tape or sleeve.
