MRC03 Operation Instruction
Fixed code Wireless Switch Receiver
A. Function
1.It is an innovation-designed receiver which is random code-learning with the corresponding multi-channel
transmitter. The operation is very easy to the users.
2.The receiver can be adjusted easily by a rotary switch. It is necessary to change code while the transmitter is
interfered by other transmitters nearby.
3.The receiver, should be installed at a place people hardly approach it, could be long-distance remote controlled.
It is very convenient for the users.
4.There is voltage surge protection inside the receiver which make the appliance free from voltage impact.
5.The red LED indicates the Power ON/OFF status.
B. Diagram & Descriptions
Item Part Description
1 Channel Switch Adjust the channel the same as that on the transmitter
2 Power Red LED . Lighting means the power is on. No light means the power is off.
3 Socket & Outlet Connect the socket to the appliance. And the outlet put into power supply.
C. Operation
1.Code learning Transmitter---Receiver
Adjust the code the same as that on the transmitter. Illustrated below:
Notes: If interfered by othertransmitter, please change code correspondingly.
2.Channel: Receiver---Transmitter
As illustrated below, there are 4 channels on the receiver (1,2,3,4),the same as the transmitter.
If the 4 receivers are connected, please sequentially adjust the respective channel as （1,2,3,4）.
3.Controlling: Transmitter---Receiver
Suppose there are 4 receivers and their channels are （1,2,3,4），make sure all receivers are put into power supply
socket, if press “ON” button of 1 channel on the transmitter, the corresponding 1receiver will be switched on.
Likewise, if press “ON” button of 2 channel, the corresponding 2receiver will be switched on too.
Allthe 4 channels should be in the same status respectively.
D. Connecting
1.Switch off the appliance
2.Plug the appliance into the socket of the receiver then connect the receiver with power supply.
3.Switch on the appliance

MRC03 Operation Instruction
Fixed code Transmitter
A.Function
1. It is an innovation-designed wireless multi-channel transmitter which is random code-learning with the
corresponding multi-channel wireless receivers. The operation is very easy to the users.
2. The transmitter can be adjusted easily by a rotary switch. It is necessary to change code while the transmitter
was interfered by other transmitters nearby.
3. Every transmitter can control up to 4 channels (1ON,1 OFF,2ON,2OFF…etc).While each channel can control
several receivers.
4. LED can indicates the signal transmission status
5. It can work for2-year super long standby time.

6 Battery case Pull out the battery case, you can replace the used the battery.
C.Operation
1. Code Learning: Transmitter---Receiver
Adjust the code the same as that on the receiver. Illustrated below:
Notes: If interfered by other transmitters, please change the corresponding code.
2. Channel: Transmitter---Receiver
As illustrated below, there are 4 channels on the transmitter(1,2,3,4）the same as the receiver.
If there are 4 receivers are connected, please sequentially adjust the respective code as（1,2,3,4），
3. Controlling: Transmitter---Receiver
Suppose there are 4 receivers and their codes are （1,2,3,4）make sure all receivers are put into power supply
socket, if press “ON” button of 1channel on the transmitter, the corresponding 1receiver will be switched
on.Likewise, if press “ON” button of 2channel, the corresponding 2receiver will be switched on too.
All the 4 channels are in the same status respectively.
Notes While there are two or more receivers with same channels(i.e. 3Channel),if press “ON” button of the
3channel, all the receivers will be switched on; on the contrary ,if press “OFF” button of the 3channel, all the
receivers will be switched off.
