WARNINGS AND PRECAUTIONS
This section contains important information relating to the operating instructions for this device. It also contains information
about how to use the device safely. Read this information carefully before using the device.
WATERPROOF CASING
USB, SIM, SD and Headset jack covers must be securely in place, to ensure the device is waterproof.
ELECTRONIC DEVICE
Power off this device if you’re in a situation where using the device is prohibited. Do not use your device if it could cause
damage or interference with electronic devices.
MEDICAL DEVICE
Follow rules and regulations set forth by hospitals and health care facilities. Do not use this device when it is prohibited.
Pacemaker manufacturers recommend that a minimum distance of 6 inches be maintained between a device and a pacemaker
to prevent potential interference with the pacemaker. If you have a pacemaker, use the device on the opposite side of the
pacemaker and do not carry the device in your front pocket.
POTENTIALLY EXPLOSIVE ATMOSPHERE
Power off the device in any area with a potentially explosive atmosphere, and comply with all signs and instructions. Areas
that may have potentially explosive atmospheres include the areas where it is advised to turn off a vehicle engine. Triggering
of sparks in such areas could cause an explosion or a re, resulting in bodily injuries or even death. Do not turn on the device
at refuelling points such as service stations. Comply with restrictions on the use of radio equipment in fuel depots, storage,
and distribution areas, and chemical plants. In addition, adhere to restrictions in areas where blasting operations are in
progress. Before using your device, watch out for areas that have potentially explosive atmospheres that are often, but not
always, clearly marked. Such locations include areas below the deck on boats, chemical transfer or storage facilities, and
areas where the air contains chemicals or particles such as grain, dust, or metal powders. Ask the manufacturers of vehicles
using liqueed petroleum gas (such as propane or butane) whether this device can be safely used in their vicinity.
BATTERY AND CHARGER
• Unplug the charger from the electrical plug and the device when not in use.
• The battery can be charged and discharged hundreds of times before it eventually wears out.
• Use the AC power supply dened in the specications of the charger. An improper power voltage may cause a re or a
malfunction of the charger.
• If battery electrolyte leaks out, ensure that the electrolyte does not tap skin and eyes. If the electrolyte tapes skin or
splashes into eyes, wash eyes with clean water immediately and consult a doctor.
• If there is a case of battery deformation, color change, or abnormal heating while charging, stop using the device
immediately. Otherwise, it may lead to battery leakage, overheating, explosion or re.
• If the USB power cable is damaged (for example, the cord is exposed or broken), or the plug loosens, stop using the cable
at once. Otherwise, it may lead to an electric shock, a short circuit of the charger, or a re.
• Do not dispose of this device in re as it may explode. Batteries may also explode if damaged.
• Do not, modify or remanufacture the device; attempt to insert foreign objects into the device; immerse or expose the
