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.
