We will reply you as soon as possible.
Introduction:
This superheterodyne decode module is a high-performance RF wireless
receiver module. It adopts a European brand industrial-grade RF wireless
receiving chip, it has high receiving sensitivity and strong
anti-interference ability. It has 12 industrial grade microcontroller
decoded high level outputs. It has good confidentiality, strong
compatibility, large memory capacity, and can store about 10 remotes with
different codes.
Application:
This RF wireless receiver module can be directly applied to various wireless
products. For example, remote controls, monitoring, smart home, remote
control switches, remote control lights, remote control toys, anti-theft
alarms, garage doors, roller shutter, road barrier, retractable doors and so
on.

With 12 decoding outputs
12 Different Control Modes: Self-locking, Momentary, Interlocking, and 9
mixed modes
Operating Temperature: -20°C ~ +80°C
Size: 38 x 15 x 5 mm (1.5 x 0.6 x 0.2 inches)
Notes:
It is best to use the antenna of 1/4 wavelength, for antenna has a great
impact on receiving effect of the module: normally using 50Ω single core
cable. For frequency 433MHz, the length of antenna is about 17cm. The
position of antenna also affects the receiving effect of the module. When
installing the antenna should be extended as much as possible and be away
from the shield and the place in high pressure and interference.
It usually works with a remote with 12 buttons or 12 remotes with one
button.
When working with a transmitter, the transmit frequency, coding mode and
timing resistor of the transmitter should match with this receiver module.
Setting different working modes (By a 12-button transmitter, such as model
CV-12):
The receiver module will be set in Self-locking mode before leaving the
factory, if you want to use another mode, please follow the following steps.
Attention: When switching working modes, you need to delete all transmitters
codes first.
1) Setting Momentary mode (Channels 1~12): When the receiver module is in
the learning status, press the button 1 on the transmitter.
2) Setting Interlocking mode (Channels 1~12): When the receiver module is in
the learning status, press the button 2 on the transmitter.
3) Setting Self-locking mode (Channels 1~12): When the receiver module is in
the learning status, press the button 3 on the transmitter.
4) Setting Self-locking (Channels 1~6) + Momentary (Channels 7~12) mode:
When the receiver module is in the learning status, press the button 4 on
the transmitter.
5) Setting Interlocking (Channels 1~6) + Momentary (Channels 7~12) mode:
When the receiver module is in the learning status, press the button 5 on
the transmitter.
6) Setting Interlocking (Channels 1~6) + Self-locking (Channels 7~12) mode:
When the receiver module is in the learning status, press the button 6 on
the transmitter.
7) Setting Interlocking (Channels 1~3) + Interlocking (Channels 4~6) +
Interlocking (Channels 7~9) + Interlocking (Channels 10~12) mode: When the
receiver module is in the learning status, press the button 7 on the
transmitter.
8) Setting Interlocking (Channels 1~4) + Interlocking (Channels 5~8) +
Interlocking (Channels 9~12) mode: When the receiver module is in the
learning status, press the button 8 on the transmitter.
9) Setting Momentary (Channels 1~3) + Interlocking (Channels 4~6) +
Interlocking (Channels 7~9) + Self-locking (Channels 10~12) mode: When the
receiver module is in the learning status, press the button 9 on the
transmitter.
10) Setting Momentary (Channels 1~3) + Interlocking (Channels 4~6) +
Momentary (Channels 7~9) + Interlocking (Channels 10~12) mode: When the
receiver module is in the learning status, press the button 10 on the
transmitter.
11) Setting Momentary (Channels 1~9) + Interlocking (Channels 10~12) mode:
When the receiver module is in the learning status, press the button 11 on
the transmitter.
12) Setting Momentary (Channels 1~9) + Self-locking (Channels 10~12) mode:
When the receiver module is in the learning status, press the button 12 on
the transmitter.
How to pair the transmitter to the receiver module:
Notice: We have paired the transmitter to the receiver module before leaving
the factory.
1) Press the learning button in the receiver module and the signal LED on
the receiver module turns on, this indicates that the receiver module enters
the learning status.
2) Press the corresponding button on the transmitter according to the
working mode you need, if signal LED flashes once and then goes off, this
indicates that the pairing is successful.
3) The receiver module can learn 10 transmitters with different codes.
How to delete all transmitters codes stored in the receiver module:
We have paired the transmitter to the receiver module, if you don’t want the
receiver module to work with the transmitter, you can delete all
transmitters codes stored in the receiver module.
Operation: Press and hold the learning button in the receiver module for 8
seconds, the signal LED flashes quickly and then goes off, this indicates
that all stored codes have been deleted successfully.
