The Xsens DOT sensor contains a Lithium Ion Coin cell battery. For safety reasons: 

Strictly prohibits opening the DOT sensor. 

-

 

Strictly prohibits heat or throw the DOT sensor into the fire. 

-

 

Strictly prohibits use leave the DOT sensor close to fire or inside of a car where the 
temperature may be above 60

. Also do not charge / discharge in such conditions. 

-

 

Thoroughly read the user’s manual before use, inaccurate handling of 

the lithium-

ion  rechargeable  cell  may  cause  leakage,  heat,  smoke,  an  explosion,  or  fire, 
capacity decreasing. 

-

 

Strictly prohibits put cell into a microwave oven, dryer, or high-pressure container. 

-

 

When the Xsens DOT is not used for an extended period, store it in a place with low 
humidity and low temperature.
