objects as well as small parts that the children could swallow. In case a child 
swallows any of them, please contact a physician immediately 

•  Do not leave batteries and packing material lying around unattended; they can be 

dangerous for children if they use them as toys 

•  In case the device is going to be unused for an extended period of time, remove the 

batteries to prevent them from training 

•  Expired or damaged batteries can cause cauterization on contact with the skin. 

Always, therefore, use suitable hand gloves in such cases
