blasting operations are in progress. Before using the 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 liquefied
petroleum gas (such as propane or butane) whether this device can be safely used in their vicinity.

Otherwise, the device may hurt you owing to the strong force when the air bag inflates.
Do not use your device while flying in an aircraft and before boarding an aircraft. Using wireless
devices in an aircraft may cause danger to the operation of the aircraft and disrupt the wireless
telephone network. It may also be considered illegal.
Operating Environment
Do not use the device in dusty, damp, and dirty places or places with magnetic fields. Otherwise, it
may result in malfunction of the circuit.
On a stormy day with thunder, do not use your device when it is being charged, to prevent any danger

and health.
Federal Communications Commission (FCC) Notice (United States): Before a wireless device model is
available for sale to the public, it must be tested and certified by the FCC that it does not exceed the limit
established by the government-adopted requirement for safe exposure.
The SAR limit adopted by the USA and Canada is 1.6 W/kg averaged over one gram of tissue. The highest
SAR value reported to the FCC for this device type is compliant with this limit.
Body Worn Operation
Important safety information regarding radiofrequency (RF) radiation exposure is as follows:
To ensure compliance with RF exposure guidelines, the device must be used with a minimum of 0.5cm
distance from the body.
Failure to observe these instructions could result in your RF exposure exceeding the relevant guideline
limits.
