Your phone is a product of superior design and artisanship and should be treated with care. The following
guidelines may help you maintain the warranty obligations with regard to the terms of Maintenance Clauses,
which can extend the useful life of your device.
Keep the phone and all its parts and accessories away from children.
Keep the phone dry. Precipitation, humidity, and liquids may contain minerals that can corrode electronic
circuits.
Do not use or store the phone in dusty areas as knock-down components may be damaged.
Do not store the phone in extreme temperatures. High temperatures can shorten the life of electronic
devices, damage batteries and warp or melt certain plastics components. Cold temperatures may result in
moisture forming inside the phone when temperatures rise, which may damage the electronic circuits.
Do not attempt to disassemble the phone’s casing. Nonprofessional handling of the phone may cause
damage and void the warranty.
Do not drop, knock or shake the phone to avoid damage to the internal circuitry.
Do not apply or clean the device with chemical products, detergents or scouring products.
Do not use paints on or in the phone. Blockage of sundries inside the knock-down components may affect
the normal operation of the device.
The abovementioned guidelines are applicable to your phone, batteries, charger and accessories. If you
experience difficulties with any of these components, contact the nearest qualified repair institution.
