How to connect the transmitter and receiver

*Please connect the cable to the same terminal as above according to the equipment you use.

Install or disassemble the shoe adapter

Install the shoe adapter

Push the bottom of the belt clamp ( 1 ) to create a certain space between the belt clamp and the receiver, align the belt clamp with the two vertical grooves on the shoe adapter, and then insert the adapter in the direction of the arrow ( 2 ), fully push the shoe adapter until the belt clamp is fitted into the horizontal groove on the adapter handle.

Disassemble the shoe adapter

Push and hold the position marked ” PUSH ” on the shoe adapter ( 1 ), separate the horizontal part of the belt clamp from the horizontal part, and groove on the shoe adapter ( 2 ), then push the shoe adapter in the direction of the arrow ( 3 ).

Matching of receiver and transmitter

Before leaving the factory, the transmitter and receiver of each product have been set up in pairs and can be used directly when starting.
If the radio signals of the transmitter and receiver are connected properly, the green light indicator of the receiver will belong on, and the parameters of the display screen will be the same as that of the transmitter; if not connected, the receiver indicator will not be on.

Remark:
Channel 1 and channel 2 of the receiver can be adjusted separately. When two transmitters are used, transmitter 1 and transmitter 2 do not need to keep the same channel.
Just set the CH-A receiver to the same channel as transmitter CH-A and CH-B of the receiver to the same channel as transmitter CH-B.

1. If you use multiple CR-2 wireless microphone systems, make sure that each system is set to a different channel, which can reduce the possibility of mutual interference.
2. If the transmitter and receiver are connected, the status light of the receiver remains blue. Conversely, if the status light of the receiver is off, it means that the transmitter and receiver are disconnected.
3. The setting result will be saved in memory automatically. Turn on the transmitter and receiver again, and the channel, channel, and other information will be consistent with the last setting.
4. Insert the headset into the receiver for monitoring. When the volume of the headset is low, gradually adjust the volume to a comfortable volume to monitor the transmission.
5. After confirming that the transmission quality is good, install the transmitter and receiver.
6. When you set the transmission channel, the transmitter cannot be used to transmit signals.
