• Do not drop the device or battery. Doing so may
damage the device or battery.
• If the device standby time shortens significantly,
replace the battery.
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.
