Before you clean or maintain the device, stop using 
it, stop all applications, and disconnect all cables 
connected to it.
•  
Do not use any chemical detergent, powder, or other 
chemical agents (such as alcohol and benzene) to 
clean the device or accessories. These substances 
may cause damage to parts or present a fire hazard. 
Use a clean, soft, and dry cloth to clean the device 
and accessories.

cards and phone cards, near the device for extended 
periods of time. Otherwise the magnetic stripe cards 
may be damaged.

Do not dismantle or remanufacture the device and its

manufacturer from liability for damage. In case of 
damage, contact an authorized service center for 
assistance or repair.
