• 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

device and accessories.
• Do not place magnetic stripe cards, such as credit cards and phone
cards, near the device for extended periods of time. Otherwise the
magnetic stripe cards may be damaged.
