Cleaning and maintenance
•
Keep the device and accessories dry. Do not attempt
to dry it with an external heat source, such as a
microwave oven or hair dryer.
•
Do not expose your device or accessories to extreme
heat or cold, which may interfere with proper
function and may lead to fire or explosion.
•
Avoid collision, which may lead to device
malfunctions, overheating, fire, or explosion.
•
Before you clean or maintain the device, stop using
it, close all applications, and disconnect all cables
connected to it.
•
Do not use chemical detergents, powders, or other
agents (such as alcohol or 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
bankcards and phone cards, near the device for
extended periods of time. Otherwise, these cards
may be damaged.
•
Do not dismantle or attempt to modify the device or
its accessories. This voids the warranty and releases
the manufacturer from liability for damage. In case
of damage, contact an authorised service centre for
assistance or repair.
