Important Safety & Handling Information
Disassembly and Retrofit
Do not attempt to disassemble or retrofit the terminal yourself. Unauthorized disassembly or retrofit will void the warranty.
External Power Supply
Use only the included AC adapter. Otherwise there is a risk of damage to the terminal.
Abnormal Situation
Keep the terminal away from fire or heat sources. If there is unusual odor, overheating or smoke during charging, immediately
cut off the power and disconnect the AC adapter, and contact your dealer or Newland customer service center. Continued
use in this case may result in fire or electric shock.
Drop Damage
If the terminal is damaged due to a drop from high place, immediately cut off the power and contact your dealer or Newland
customer service center.
LCD Screen
Do not press against or strike the LCD screen. Otherwise it may damage the screen. When handling a cracked or shattered
screen, do not touch the liquid that has leaked from it to avoid skin burn or infection.
Stacking Heavy Objects
Do not place heavy objects on the terminal as those objects may fall and cause injury.
Electronic Device
Switch off the terminal near high-precision electronic devices. The terminal may affect the performance of these devices.
Such devices include hearing aids, pacemakers, fire alarm systems, automatic gates, and other automatic control
