environment.
• Do not store the terminal in extremely hot or cold areas.
• Do not shake or drop the terminal.
Cleaning the
NURIT 8000
Disconnect the device from the power supply and any peripherals before cleaning.
To clean the NURIT
8000
• Gently wipe off dirt from the body of the terminal with a soft, damp, lint-free
cloth. A very mild dishwashing detergent can be used to dampen the cloth.
• If available, a low-pressured blower can be used to remove dirt accumulated
around the keypad buttons.
• Use a soft cloth, an eyeglass lens wiper, or a lens blower to remove dust and
dirt from the LCD screen.
CAUTION
• Opening or disassembling the terminal in any way automatically erase all
secret encryption keys and will render the PIN pad inoperable.
• Opening the terminal will void any warranty and security certification. It may
also result in irreversible damage to the unit’s electronic circuitry.
