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.
•
If the device screen is damaged, stop using the device
immediately. Do not touch or attempt to remove the broken
parts. Contact an authorised service centre as soon as
possible.
Emergency calls
The availability of emergency calls is subject to the signal quality,
service provider policy, and local laws and regulations. Never rely

emergencies.
