We have a pair of herelink receiver and transmitter units in our laboratory that have not been used for about 3 years but now we are currently planning to use them for a project. This device was purchased about 4-5 years ago. Since it has not been used for a long time, we tried to update the software and we were successful. However, we are asked for the product key information, but we do not have this information and we cannot learn from which local vendor the product was purchased by the university because it has been a long time. The information on the product box and on itself is as follows:

SN: HX4-06071-950-0553
