Product details:

Detailed instruction Repeater is a TX/RX device repeating the RF signal. The RF signal should be: 1) Same frequency to the repeater. 2) Oscillating resistor should be matched with repeater. This repeater supports PT2262/1.2M, PT2262/2.2M, PT2262/3.3M, PT2262/4.7M, PT2240/1.5M (IC/OSC), and it has learning function, up to learn 100 pcs transmitters. So it can repeater the one learned, to avoid others transmitters.
