TX553 FOUR-BUTTON TRANSMITTER The TX553 transmitter is a replacement RF transmitter. The transmitter comes with 4 push-button switches. 1) Press Upper and LEFT push-button switch on control first receiver (alarm the system, door lock ). 2) Press Upper and RIGHT push-button switch to control second receiver (It can be an alarm system or electric device). 3) Press Lower RIGHT push-button switch to control third receiver (It can be an alarm system or electric device). 4) Press Lower RIGHT push-button switch to control forth receiver (It can be an alarm system or electric device). TRANSMITTER BATTERY REPLACEMENT If the range of your transmitter deteriorate, it is possible that you need to replace the battery. 1) Release the screw from the back of transmitter and remove upper transmitter case. 2) Remove old battery from transmitter. 3) Install a new battery (12 volt) noting the (+) and (-) marks in the battery area of the transmitter. 4) Replace upper transmitter case with area, do not damage the inside components. 5) Tighten the screw on the back of transmitter. 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.

Operational Description

TX553 Operational Description The car alarm transmitter is a low powered, hand held unit for remote controlling the car locks and other features. See the function descriptions in attached. The transmitter is powered by a 12 volt battery. It is designed to operated on a single fixed frequency at 433.92 MHz. See the attached block diagram and schematic. There are 4 buttons trigger the integrated circuit (U1) which produces the digital control signals and will modulate the carrier signal. The carrier signal is generated by a LC oscillator/ amplifier circuit comprised of a npn transmitter (Q1)and VC, L1, C1 ,C4. The modulated output of the RF amplifier stage is coupled to the PCB strip antenna. The coupling network comprised of C2,C3 and R1. The strip antenna is attached on PCB permanently around 10 mm. The transmitter is manually operated by the buttons pushed and will automatically deactivate within 3 seconds after the button being released. This feature is incorporated by the U1 internally. All tuning and verification are performed by the manufacture and there are no adjustments can be made by the user. No external ground is required or used with this transmitter.
