FCC ID: EMOIH52RC To these problems,we had revised the related data , please see the reply as follows: Response: I had added the photos of the top and bottom of TX board in the internal photos Please see the EMOIH52RC_Internal photos.rev1.pdf Response: Please see the EMOIH52RC_Schemetics.rev1.pdf Response: Test equipment had been cabibrated on the Jun.3,2006.But I forgot chage them because my careless. Now I had revise them. Please see the EMOIH52RC_Test report.rev1.pdf Response: Please see the page 17 and 18 of EMOIH52RC_Test report.rev1.pdf; Response: I tested truly three axis of lie orientation and slide orentation and stand orientation. And lie orientation is the worse case emissons,so we only reported the lie orientation. Please see 3.2 section of the EMOIH52RC_Test report.rev1.pdf

Circuit description The emitter uses expert IC, using RF-controller theory. It’s work manner is FSK, emit frequency is 433.7MHz. Pressing one button, the IC will export a control signal to exterior circuit. It will be amplified through amplifer stage. The pulse width is controlled by software, and it is 0.1S. The frequency warp is ±0.2MHz. Copper or a lead is added on ANT, it can increase the control distance.
