January 29, 1999 To: Mr. George Tannahill Federal Communications Commission Equipment Authorization Branch Subject: Electronic Submission for FCC ID: ADTVRA671 Dear Mr. George Tannahill Thank you for your cooperation on our order. Electronic submission of FCC Form 731 was send by Japan Quality Assurance Organization (JQA) as test firm, but in the application referenced above, we have confirmed them [email protected] almost of the files submitted were not openable by your system. We will try the Electronic Filing continually. Consequently after this we will hope that the contact person on file with the FCC changes Mr. Teruaki Yamasaki (Funai Electric Co., Ltd.) into Ms. Makoto Okada ([email protected]). For retrying of sending test report file, please reply above the mail address. Yours faithfully, (Ms) Makoto Okada EMC Div. Japan Quality Assurance Organization Kita-Kansai Testing Center

Explanation of Remote Locator Characteristics The customer will walk over to the set, press on “POWER” button, and an RF signal will be transmitted from the set, that will be detected by an RF receiver installed in the handset. If the correct identify code is detected by the handset, an audio beeper will sound to help the customer locate the misplaced remote. RF receiver in the handset will receives AM (amplitude modulated) signals at a carrier frequency of 390MHz+/- 200kHz, for a time period of 4.9 seconds from the part of transmitter inside the set. A discrete RF amplifier tuned to 390 MHz enhances the input signal to the regenerative detector. The encoded AM signal is demodulated by a superregenerative detector circuit. Two operational amplifier in single IC follow regenerative detector. The first op amp amplifier the detected data and the second is used as a data slicer to improve the data signal to noise ratio.
