Waterproof 4 Keys 433 Mhz RF Remote Control
Waterproof 4-key
Product introduction:
The remote controller is mainly used for data reception and signal control.
It is available For electric doors, garage doors, rolling shutter door/window,
remote control switches, remote control Door locks, LED lighting, industrial
automatic control, receiving controllers Wireless anti-theft alarms, etc. Its
internal circuit design is advanced and adopts a fixed coding chip. The RF
circuit adopts a sound meter to stabilize the frequency, which has the
characteristics of high stability and low power consumption, and can be used
with a variety of RF modules of our company.

Product shape:
Remote control coding Description:
One frame data = synchronization header + 16-bit address data + 8-bit key-
value data 16-bit address bits (every 2 bits represents an address bit code /
/ that is, sct2260 has only 8 address codes)
Description of the working principle of the remote control:
Press the control keys SW1 to SW4 of the remote controller respectively. When
the coding MCU is powered on and the indicator light is on, the coding MCU/out
port outputs 24bit serial data (serial port baud rate 5Kbps) to the high-
frequency oscillation circuit, and then sends the signal in the form of ASK
modulation through the RF antenna.
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.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment. This
equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
— Reorient or relocate the receiving antenna.
— Increase the separation between the equipment and receiver.
–Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
— Consult the dealer or an experienced radio/TV technician for help.
