Precautions
Maintenance
Keep it dry. Rain, humidity and other types of liquids or moisture can contain
minerals that may cause corrosion to components. If the device does
accidentally get wet, remove the battery and wait for the radio to dry
completely before placing it back.
Do not place or store the device in environments above +45°C.
High temperatures can shorten the life span of certain components.
Do not place or store the device in cold environments below -5°C .
Otherwise, once the surrounding temperature rises, internal condensation
may develop and damage the circuit board and LCD display.
Do not drop, hit, or smash the device.
Do not use harsh chemicals, cleaning solvents, or strong detergents to clean
the device. Use a clean, soft, dry cloth to clean the screen.
Do not attempt to disassemble the device to adjust internal parameters.
Lithium Battery Safety Instructions
Improper replacement of the lithium battery may result in an explosion.
Replace only with a lithium battery of the same type or equivalent (the lithium
battery used in this device is a 18650 rechargeable lithium battery with a
protection circuit).
Do not charge non-rechargeable batteries.
Do not expose the battery to heat sources (e.g. sunlight, fire), low
temperatures, humidity, or high pressure.
Dispose of the battery properly and prevent children from playing with electric
currents.
Do not short-circuit or disassemble the battery. If the battery is seriously
inflated, please do not continue to use it.
If not using for an extended period of time, remove the battery and store it in
a safe manner. Please use non-conductive material to wrap the battery in
order to avoid direct contact with metal. You can avoid performance loss by
keeping the battery in a cool dry place.
Please consciously abide by aviation regulations; lithium batteries are strictly
prohibited from placing into checked luggage.
