HERMO N LABO RATORIES June 24, 2007 American TCB 6731 Whittier Ave Suite C110 McLean, VA 22101 Attn: Mr. R. Fabina, Examining Engineer RE: your e-mails dated June 20, June 23, 2007; Risco Ltd. FCC ID:JE4RET312PR4, ATCB005043 Dear Mr. Fabina, Please find below the answers to your question No.2. Risco Ltd. confirms that: The transmitter was tested in “low power mode”. The jumper controls the RF power and not the IR sensitivity. “High power” is according to the European limitations, “Low power” - according to the FCC limitations. This products is not purchased off the shelf, it is intended only for installation by a trained and professional installer. The product is shipped with an installer manual only, and there is a warning not to use the “High power” for countries with FCC compliance. So the trained installer knows in the US and Canada to put the jumper on “Low power” position. The end user is not authorized to touch the unit, or open it, and so he cannot modify the RF power. Sincerely, Marina Cherniavsky, certification engineer Hermon Laboratories
