Frequently asked questions
Which transmitter is designed to work with the RX-2B?
The listing names the TX-2B as the companion transmitter, which includes an auto power-off function. Make sure the transmitter and receiver operate on the same RF frequency and are designed as a pair.
Can I power the RX-2B from a single Li-ion cell?
Yes, as long as the supply stays within 1.5 V to 5.0 V. A single Li-ion cell at about 3.7 V nominal falls within this range, but do not exceed 5.0 V.
