Working Mode:
1. Different frequency uplink and downlink difference forwarding (and conventional relay station), A machine as the uplink receiver, and B machine as the 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 mode. When using it, the volume of the intercom as a receiving should be adjusted to the maximum! Single/two-way relay box frequency setting prompt.
4. One-way relay box forwarding mode (regular repeater mode)! The A machine receives the and the B machine transmits the . The receiving/transmitting machine must be set to two different frequencies. The frequency set by the conventional transmitter is higher than the receiver frequency, and the high/low frequency is low. The high/low frequency difference is generally 10M, and the larger the frequency difference, the better.
5. Do not reverse the jack of the one-way relay box during use, otherwise the relay box will not work.

Notes:
1. This relay box is an audio 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 delay time is too long (more than 3 seconds), the transmitter's transmitting antenna is too close to the relay box to cause the to interfere with the relay box! The external walkie-talkie antenna can be used to solve the interference problem!
