A920 REFERENCE GUIDE
10. What is the RESET button
?
The reset button is used to reboot the device. It is located on the backside of the device.
11. What should I do if the touchscreen is unresponsive or lags?
First confirm that the surface of the screen is free from liquids. If there is a protective plastic film over
the screen, remove it before attempting to use the device again. Check to see if there are any metallic
objects touching the screen or if there is a source of magnetic waves near the device. If there are,
remove the metallic objects and keep the device away from any sources of magnetic waves before
attempting to use it again.
12. What should I do if the camera is not reading barcodes?
1) Confirm that the code you are reading is placed properly with the locator light next to the camera
and maintain approximately 10 cm from the camera. Also make sure that the barcode or QR code
being read is not covered, stained, or otherwise damaged.
2) If there are signs of damage, replace the code being read. Check to see if the camera lens is clean. If
there is a protective plastic film over the lens, remove that as well before attempting to use the
camera again.
3) If reading the code off an electronic display, increase the resolution or screen brightness before
attempting to read the code again. If there is no damage to the code, it's possible that the device
does not support the code you are attempting to read, in which case you should contact an agent
from your local vendor for possible solutions.
