[. . . ] If you have any questions regarding RF exposure and safety standards please refer to the Federal Communications Commission Office of Engineering and Technology's report on Evaluating Compliance with FCC Guidelines for Human Radio Frequency Electromagnetic Fields (OET Bulletin 65). NEVER attach an antenna or internal antenna connector during transmission. R NEVER apply more than 16 V DC, such as a 24 V battery, to the [DC13. 8V] jack on the transceiver rear panel. This could cause a fire or ruin the transceiver.
