• 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.
• 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

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

immediately stop using the device. Do not touch or
attempt to remove the broken parts. Promptly contact
an authorized service center.

critical communications like medical emergencies.
