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. Twoway forwarding, when the A machine receiver, the B machine transmits. When the B machine receives, the A machine launches. The twoway 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! Singletwoway relay box frequency setting prompt. 4. Oneway relay box forwarding mode (regular repeater mode)! The A machine receives the signal and the B machine transmits the signal. The receivingtransmitting machine must be set to two different frequencies. The frequency set by the conventional transmitter is higher than the receiver frequency, and the highlow frequency is low. The highlow frequency difference is generally 10M, and the larger the frequency difference, the better. 5. Do not reverse the jack of the oneway relay box during use, otherwise the relay box will not work. Notes: 1. This relay box is an audio trigger mode, so please adjust the volume of your walkietalkie 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 walkietalkie antenna can be used to solve the interference problem! No power supply needed, plug and play.
