Different frequency uplink and downlink difference forwarding (and conventional relay station), A machine as the signal uplink receiver, and B machine as the signal downlink transmitter. The relay has been achieved.2. Two-way forwarding, when the A machine receiver, the B machine transmits. When the B machine receives, the A machine launches. The two-way forwarding function is achieved.3. This relay box is an audio trigger mode. When using it, the volume of the intercom as a receiving signal should be adjusted to the maximum! Single/two-way relay box frequency setting prompt.Notes:1. This relay box is an audio trigger mode, so please adjust the volume of your walkie-talkie to the maximum when using it, otherwise there may be no forwarding status.2. If the transmission delay time is too long (more than 3 seconds), the transmitter's transmitting antenna is too close to the relay box to cause the transmission signal to interfere with the relay box! The external walkie-talkie antenna can be used to solve the interference problem!
