Normally, we would adapter remote control and receiver.
If the item you received has not been adapted Or you need to add accessories, Please follow the instructions below
   
Learning method and steps:
In normal operation mode, LED (D1) will be lit, when receiving a valid remote control (EV1527 / PT2262) key value, LED will flash.
  
Clean code: hold the button to press.LED offs, keep pressing about 8 seconds until LED lights. At that time, clean code completion (Note: After the implementation of clean code, previous remote controls do not exist.
  
Adaptation (learning):
Step 1 (into the learning mode):trigger the key button, LED offs;
  
Step 2 (adapter channel 1): press the first button of remote control and then, LED offs after flashes for four times. This time means that it had learned the value of the first button
  
Step 3 (Adaptation Channel 2): Press the second remote control, LED offs after flashes 4 times, This time means that it had learned the value of the second button
   
Step 4 (adapter Channel 3): Then press the remote's third button, LED offs after flashes 4 times, This time means that it had learned the value of the third button
  
Step 5 (Adaptation Channel 4): Then press the remote control's fourth button, LED lights after flashes 4 times, This time means that it had learned the value of the fourth button.
  
NOTE: The process must be completed within 15 seconds

one channel is Delay time  , the other channel is Delay Time  ;
 
3:  Time of each delay mode  is proportionally increased. For example, you want to channel 1 to delay 50 seconds , 500seconds and 5000 seconds, you can first seting channel 1 is set to "delay 1 (Delay Mode 3), turn around (CH1_adj) adjustable resistance, so that channel 1 delay 50 seconds; if the mode is set to "delay 2 (mode 4), the delay time becomes 500 seconds, if the mode is set to" delay 3 (mode 5), the delay time becomes 5000 seconds
 
4 With a suitable screwdriver and gently rotating adjustable resistance;Clockwise, increasing delay,Counter-clockwise, the delay is reduced

Use Method:
This is the DTMF audio controller with four channels, any phone or fixed telephone with DTMF key code remotely controls product relay "open" and "close".(the majority of smartphones and functions machine are DTMF code). Our software "DTMF Dial" (installed in a computer) can be also provided to control relays.
As shown above, by phone remote control relay. You need two phones, one as a receiver (phone_1), the other one as a transmitter (phone_2); mobile phone_1 connected by DTMF audio cable 3.5MM audio controller (the controller to be powered), and then using phone_2 ( may be a fixed telephone) call the phone_1, phone_1 answered, so that two phone call each other; then dial 1/2/3/4 by phone_2 keypad to control four relays .
 
As shown above, you can install one of our "DTMF Dial" software in your computer, through the software control DTMF audio controller. At first, use 3.5MM audio cable to the computer video port and audio port controller, then click on the software to control relays 1/2/3/4.
   
Caution: 
1 DTMF audio controller must use stable work of DC 12V power supply (recommendations 1A or above the power adapter)
2 remote control the controller by a mobile phone, the receiver must be the phone with 3.5MM audio interface, the transmitter can be a cell phone or landline
3 as a receiver of the phone or a computer installed the "DTMF Dial" software must output a sound (not muted), or they will not control relays.

The on-chip adaptive cell can adjust charging current automatically based on the output capability of input power supply, so SD05CRMA is ideally suited for the solar-powered systems, or the applications that need to charge lithium-ion battery or lithium polymer battery with an input power supply whose output capability is limited.
 
  
If your solar panel is 5V, then you can use it directly. Of course, the module can also be powered by a 5V DC power supply.
  
If your solar panel is larger than 5V(e.g. 6V 9V 12V 18V 24V 36V 48V), you can convert it to 5V with DC-DC buck module(e.g. DD2712SA_5V/DD8024TA_5V).
 
   
 
 
 
The charging current can be changed by changing the value of resistor R1
