Delete existing data: Press learning button(on the receiver) 8 times. Response: LED flashes 7 times. 2. Learning remote code: press learning button(on the receiver) once, twice or three times (see below). LED turns on: learning mode is active. Press any button of the remote control. LED indicator flashes three times: learning successfully completed. 3. Test: after the above operation , the receiver board can be controlled by the remote control. More transmitters with different IDs can be learned and stored additionally, starting with step 2. A mixture of different modes is possible. Button usage (sets mode and starts pairing process): Press once: Inching mode (Momentary Mode) Press twice: self-Lock Mode (Toggle-Mode of the 4 Channels) Press three times: interlocked mode (selected channel active and be cleared, if another channel becomes active) ProductSiteLaunchDate : 2021-01-12T06:13:22.043Z Size : Small Style : RX480E+TX118SA 3SETS SupplierDeclaredDgHzRegulation : not_applicable SurroundSoundChannelConfiguration : 4 Channel UnspscCode : 25174400 Voltage : 50 volts WirelessCommunicationTechnology1 : IR WirelessCommunicationTechnology2 : RF
