Working mode:
1. Inter-frequency uplink-downlink differential forwarding (and conventional relay station), where machine A acts as the signal uplink receiver and machine B acts as the signal downlink transmitter. This achieves the relay purpose.
2. Bidirectional forwarding, when machine A is the receiver, machine B transmits. When machine B is the receiver, machine A transmits. This achieves the bidirectional forwarding function.
3. This repeater box operates on an audio-triggering basis. When using it, you should set the volume of the intercom as the receiving signal to the maximum level! Frequency setting instructions for single/dual-way repeater boxes


1. One-way relay box forwarding mode (conventional relay station mode)! Machine A receives signals, and Machine B transmits signals. The receiving and transmitting machines must be set to two different frequencies. The frequency set for the conventional transmitter should be higher than that of the receiver, and it should be "transmit high/receive low", with the frequency difference generally being 10 MHz, and the larger the difference, the better.
2. During the use of the one-way relay box, please do not reverse the plugs. Otherwise, this relay box will not work.
3. Two-way relay box plugs do not distinguish between input and output. Two-way relay box forwarding mode: Machine A receives from Machine B and Machine B receives from Machine A.
Notes:
1. This repeater box operates on an audio trigger mode. Therefore, when using it, please turn up the volume of your walkie-talkie to the maximum. Otherwise, there is a possibility of not receiving the signal.
2. If there is a long delay in transmission (more than 3 seconds), it is because the walkie-talkie transmission antenna is too close to the repeater box, causing interference to the repeater box! You can solve the interference problem by using an external walkie-talkie antenna.
Product Features:
1. No power supply required
2. No need to modify any part of the original walkie-talkie. Just take two handheld walkie-talkies
3. By using the earpiece jack of the two handheld walkie-talkies through this repeater box, a very practical small repeater station can be formed
4. Simple and intuitive, easy to operate
5. Compact and portable
