To: [email protected] Cc: [email protected] Subject: FCC ID:L5C0762TX Ansen Electronics Hi Alice, I see that Chris granted this today. Congratulations. I have a favor to ask. I realize that I neglected to pick up on the lack of a 15.105 statement in the users manual. Eventhough the Grant has already been issued, so that either one of us does not have any future problems with the FCC, could you request Ansen to resubmit a revised manual page showing the addition of that statement? It would just be better for all involved if they would. Thank you, and again, I apologize for my oversight. I won't be back at work until Monday Dec 3, but I will check with you then on this. Thanks again, and have a good week. Regards, Mariannne

FCC ID: L5C0762TX Circuit Description The 434MHz crystal oscillator drives the base of Q2 the final/buffer amplifier. The modulation provided by Mic. The output of Q2 has the matching network consisting of L6 and C8 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source There is no external Ant. Build in on the Printed Circuit Board. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3 Volt (“AA” size battery x 2) primary battery

Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigate all operating modes, rotated about all 3 axis (X, Y & Z) to obtain worst position, manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. *:OATS [Open Area Test Site] located at HKSTC with a metal ground plane on filed with the FCC pursuant to section 2.948 of the FCC rules, with Registration Number: 90657.
