5.Usage
      A.Match Code: Press match code button K1 for 3seconds, LED indicator lights, and press any buttons on remote control. When LED flashes 2times, it means finishing matching code.
      B.Delete Code: Press K1, not let go the hand until LED flashes 3times, and then delete code successfully.
C.

1. Select output mode: can use dip switch to select output mode:
   1. Push no.1 on dip switch to ON position, output Latch(interlock);
   2. Push no.2 on dip switch to ON position, output Toggle(self-lock);
   3. no.1 and no.2 are not pushed to ON position, output Momentary(non-lock)
   4. no.1 and no.2 are pushed to ON position, Setting is invalid, no output.

 

1. This receiver module is a bidirectional transmitting& receiving module, matching with bidirectional remote control. Customer can choose to return signal or not. If yes, push no.3 on dip switch to ON position (corresponding S1 on remote control).This receiver module will transmit a signal after receiving it from bidirectional remote control. When bidirectional remote control receives the signal, the buzzer will send the sound 'dip-'

And that indicates bidirectional remote control is normal to receive communication

Heat Sink

Heat sink is a vital component that helps to dissipate heat from electronic devices. These devices generate heat as they operate, which can damage the internal components and cause malfunctions. In this article, we will explore what heat sinks are, how they work, and why they are important.

What is a heat sink?

A heat sink is a hardware device that is used to regulate the temperature of electronic components by dissipating heat. It is usually made out of an aluminum or copper plate with fins, which help to increase the surface area and improve the efficiency of heat transfer. Heat sinks are commonly used in electronic devices such as computers, power supplies, and mobile phones.

How do heat sinks work?

The purpose of a heat sink is to transfer heat from an electronic component to the surrounding environment. When electronic components such as CPUs or GPUs become hot, the heat is transferred to the metal plate of the heat sink. The heat sink then uses its fins to increase the surface area for the transfer of heat to the air. As the air flows over the fins, it absorbs the heat and carries it away, thus cooling the electronic component.

Why are heat sinks important?

Heat sinks play a significant role in ensuring that electronic devices function correctly and have an extended lifespan. Here are a few key reasons why heat sinks are important:

1. Improved performance: When electronic components become too hot, they can malfunction or slow down. Heat sinks help to regulate the temperature of these components, allowing them to operate at their full potential.

2. Extended lifespan: Overheating can cause damage to electronic components, leading to a shortened lifespan. Heat sinks help to prevent this by ensuring that the components are kept within their safe temperature range.

3. Reliability: By preventing excessive overheating, heat sinks contribute to the overall reliability of electronic devices, reducing the risk of malfunctions and failures.

In summary, heat sinks are an essential component of electronic devices that help to regulate the temperature of electronic components. They improve performance, extend the lifespan of devices, and contribute to their overall reliability. Regular maintenance, cleaning, and replacement of damaged heat sinks are crucial for ensuring the optimal functioning of electronic devices.
