1250 Avenida Acaso, Unit F, Camarillo, CA 93012 ? Phone (805) 383-9600 ? Fax (805) 383-9001 email: [email protected] ? www.applied-wireless.com USER’S MANUAL Introduction This 433.92 MHz keyfob type transmitter is used in miscellaneous applications requiring short-range remote control of on/off functions. FCC ID: QY4KTX433 INSTRUCTION TO THE USER FCC ID: QY4KTX433 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference and (2) This device must accept any interference received, including interference that may cause undesired operation. The user is cautioned that changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. Transmission Range The transmission range of this unit depends upon the environment of the signal path, the type of receiver used and the type of receive antenna used. Using Applied Wireless RCR433 receiver or RX433 module with a Holtek 6034 decoder and a quarter wave vertical antenna, line-of-sight range of 300 feet is normal. By using a quarter wave antenna with ground plane or a dipole antenna will extend the range even further. Non line-of-site applications can have significantly shorter transmission range. Addressing For security purposes, this transmitter is capable of being programmed to one of 6,561 different addresses. The receiver must be programmed to the same address as the transmitter. The default address from the factory for both RCR receivers and KTX series transmitters is 00000000 (all encoder address pins grounded). See application note AN-104 for alternate programming instructions. Troubleshooting ??Verify power by checking transmitter LED when transmitter is operated. ??Verify address codes for transmitter and receiver are the same. ??Eliminate RF interference as a possible problem by checking operation at a different location. 1250 Avenida Acaso, Unit F, Camarillo, CA 93012 ?

Fax (805) 383-9001 email: [email protected] ? www.applied-wireless.com AppliedWireless The following guidelines are provided here for addressing KTX keychain transmitters and RCR receivers. The encoders and decoders used in these products allow for tri-state addressing. That is, each of the 8 address nodes may be set in either ground, +Vcc or open states. As shipped from the factory, the address nodes for both products are set to ground, and it is not necessary to modify these address for the products to work together. However, if a different address is desired, address nodes on both transmitter and receiver must be set to the same configuration. The following describes how to set an address node to a particular state: Open State To configure a node in the open state, the trace connecting the address node to ground must be cut. +Vcc State To configure a node in the +Vcc state, the trace connecting the address node to ground must be cut AND a connection must be made from the address node to the +Vcc node. A dab of solder is typically used to short across the solder bridge. Ground State As configured from the factory. +Vcc Address Node Ground HT6044 A0................A7 A7....................A0 KTX Board RCR Board Backside View Top View Application Note AN-0104 KTX/RCR Addressing

1 Scott McCutchan From: Scott McCutchan [[email protected]] Sent: Tuesday, April 15, 2003 12:46 PM To: [email protected] Cc: Ruby Hall Subject: FCC ID: QY4KTX433 Mr. Madlangbayan, In order for processing of this application () to continue, the following issue(s) will have to be addressed: 1) The duty cycle plot submitted is not sufficient. In order to calculate the duty cycle correction factor, please submit a spectrum analyzer plot(s) with the span = 0. One plot (approximately 100 ms) should show the entire pulse train. Include other plots as necessary so that the short and long pulses may be counted and the length of each pulsed may be determined. 2) Please verify that 433.92 is the lowest frequency generated in the device, and that the 433.92 MHz does not get divided down for any reason. 3) The test report indicates that a 120 kHz resolution bandwidth was utilized for radiated emissions testing. As per section 15.35(b), a resolution bandwidth of 1 MHz is to be used for frequency above 1 GHz. 4) Please indicate how the antenna complies with section 15.203. 5) According to the test report, the device was tested while powered by a DC power supply. As per section 15.31(e), battery powered devices shall be tested using a new battery. Please indicate whether tests were performed to determine whether testing with a new battery affects the emissions. 6) Please indicate how the device complies with section 15.231(a)(1), which states that a manually operated device shall employ a switch that will automatically deactivate the transmitter within not more than 5 seconds of being released. 7) The product description in the test report states that the device is used for remote control brake operation in a towed vehicle. This implies that this is an automatically activated transmitter, which does not agree with the rest of the information in the application. Please clarify. The item(s) indicated above must be submitted before processing can continueon the above referenced application. Failure to provide the requestedinformation within 60 days of the original e-mail date may result in application dismissal and forfeiture of the filing fee. Also, please note that partial responses increase processing time and should not be submitted. Please upload responses and/or exhibits to the electronic filing website.

The keyfob transmitter has two modes of activation, either of which is set at the factory and is not user determinable. In one mode, the keyfob is activated by the press of one of up to three buttons on the transmitter. In the other mode, one function is activated by applying 12VDC to the supply leads through a pushbutton switch, such as a footswitch. In either mode, the transmitter will turn off within 5 seconds of being released. The 433.925 MHz is the lowest frequency generated and does not get divided down to any other frequency. The Antenna is a fixed design and is incorporated onto the PCB board.
