Welding: 
                    
                    It is very important to avoid using the Trailerteck unit when 
                    welding is being carried out on the trailer. Doing so may 
                    create a current loop that will damage the unit. 
                    The unit as an electronic protection included inside and any 
                    damage to this protection will void the warranty. 
                  Power Failure: 
                    In the case of a power failure, all activated functions will 
                    be shut down. Therefore, for safety reasons, it is recommended 
                    to always have functional 12-volt battery hooked up to the 
                    device to prevent injuries which could occur from air brakes 
                    being deactivated unexpectedly.
