6. FAQ

1. Why does fog often appear on the screen?

   To ensure screen safety, a layer of tempered glass is added to the exterior. To ensure heat radiation, a gap is maintained between layers for air convection. Fog appears due to a temperature difference between the screen and the external environment, causing hot air to condense on the cooler glass surface. This fog does not affect normal use and will evaporate after several hours of operation.

2. Why are the boot times of the devices in different meeting rooms different?

   Generally, using external U disks or browsing online can introduce viruses. This can lead to the disk space being fully occupied or the system disk becoming damaged, resulting in slower boot times.

3. The attached touch pens are limited. Is there any object that can replace the touch pen for flexible writing and at the same time does not damage the screen?

   Fingers can be temporarily used for writing. If necessary, additional writing pens can be purchased.

4. After used for some time, the screen is overheated. Is it normal? Will it bring any bad influence?

   It is normal for the screen to overheat, and it will not bring any bad influence. The current heat radiation design of the machine is industry-leading and complies with international health standards.

5. Will it be harmful for eyes in case of use for a long time?

   Human eyes perceive flickering at 50 Hz and above. If the frequency is below 50 Hz, eye muscles must continuously adjust, leading to fatigue. The LCD used in this product operates at 60 Hz and 120 Hz, frequencies at which human eyes cannot perceive flickering. This significantly reduces eye fatigue compared to products with lower refresh rates.

7. Simple Troubleshooting

1. Failure to boot the product

   • Check if the AC SWITCH is flipped to "I".
   • Check the AC cable or DC adapter and try again.

2. Automatic shut down

   • Check if the sleep feature is enabled (similar to a PC).
   • Check the power status.

3. No sound, only pictures

   • Check the volume settings.
   • Check if the audio cable is properly connected.
   • Check if the product is muted.

4. Imprecise touch point

   • Check whether the touch pen or the finger is held 90 degrees vertical to the screen.
   • Check whether there are other objects touching the screen, for example, little tape or sleeve.

8. Maintenance

1) Simple maintenance

• Proper maintenance can avoid many early faults, and regular careful cleaning can keep the machine looking brand new.
• Please unplug the power plug before cleaning and maintenance to prevent electric shock.

2) Clean Screen

• Please mix and stir a small amount of fabric softener or tableware detergent with alcohol.
• Please use a soft cloth completely soaked in the mixture.
• Please take out the cloth and wring it to a half-dry state to wipe the machine screen.
• Repeat several times, paying attention not to squeeze water flow into the machine when wiping.

3) Clean Face Frame

• Please use a dry, soft, lint-free cloth to wipe the front frame.

4) No Use of Machine for A Long Time

• In case of no use of the machine for a long time, such as during holidays, please make sure to unplug the plug to prevent any possible dangers caused by power supply ripple from lightning.
