SDR-5100/5200M IrDA UHF 2-Way Sync Receiver Module CHANNEL scanning For an interference-free operation, a cleaner channel might be necessary if the current one receives too much interference. Before scanning, the transmitter must be switched off. Press and hold either channel button for 3 seconds The receiver will find and locate a clear, interference- free channel.

Instructions SQUELCH (SQ) setting When interference is encountered try reducing the sensitivity of the receiver by turning the SQ control clockwise, thus less susceptible to interference. If this still does not solve the problem it means this frequency is not suitable. Adjust the squelch back to where it was and use the scan function to locate a clear, interference-free channel.
