Helen Zhao Subject: FW: (????-??????????)RE: Megatech International Inc., FCC ID: P4SMTC8340, Assessment NO.: AN05T4831, Notice#2 7/5/2005 From: Yu Xinlu To: Helen Zhao Subject: Re: (????-??????????)RE: Megatech International Inc., FCC ID: P4SMTC8340, Assessment NO.: AN05T4831, Notice#2 Dear Helen, The following is our reply: Question #1: Please submit Operational Description. Answer to Question #1: The transmitter (the EUT) has two sticks, left-hand stick and right-hand stick. If the left-hand stick is at middle or back, the receiver (the model plane) is stopped. If the left-hand stick moves to forward, the motor of the receiver is on. The right-hand stick can be moved to the left and the right. If the right-hand stick is moved to left, the receiver (the model plane) can be moved to left. If the right-hand stick is moved to right, the receiver (the model plane) can be moved to right. So, there are five kinds of combination for transmitting operation: Question #2: The test report and the test setup photos do not show that loop antenna has ever been used for radiated measurement below 30MHz. Please explain. You may need to redo radiated measurement below 30MHz using loop antenna. Please update both report and setup photos. Answer to Question #2: Test below 30MHz was redone with loop antenna. Please refer to the revised test report NoFCC2005 - 0002. Question #4: The Schematic in the filing is for RX, not for TX, the EUT. Please resubmit correct schematic for TX. Please see the attached TX. Question # 5 : Please revise FCC ID label format to change from "FCC ID P4SMTC8340" to "FCC ID: P4SMTC8340", i.e. please add a colon. Answer to Question # 5 : The FCC ID label had been revised and a colon had been added. Question # 6 : The user manual does not contain user information as specified in FCC15.21: The client will add the"changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment." into the user manual.(please see the attached) No. Left-hand Stick Right-hand Stick The direction of the receiver Operation Mode 1 Forward —— Forward Operation Mode 2 —— Move to left Left Operation Mode 3 —— Move to right Right Operation Mode 4 Forward Move to left Forward and left Operation Mode 5 Forward Move to right Forward and right Best regards GTIHEA Yu Xinlu 7/5/2005
