Specification: Item Type:Remote Control Switch Transmitter Working Voltage: DC12V Quiescent Current: 7~8mA Operating Frequency: 315 (Optional From 315 To 433MHz) Receive Sensitivity: -103dBm Coding Method: Pair Code Output Status: Jog / Interlock / Self-Lock Size:115 X 73 X 16mm / 4.53 X 2.87 X 0.63in Distance: 1000m (This Distance Is The Theoretical Distance Without Interference, The Actual Application Is Reduced Due To The Use Environment, Please Estimate According To The Marked 10%-30%) Remote Control Battery: 12V 23A (Not Included) Remote Control Battery Size: Diameter:1cm / 0.39in Height:2.8cm / 1.1in Package List: 1 x Receiver Board 1 x Remote Controller Mode introduction: Self-locking: Press A to open, then press A to close, and the rest of the keys are analogized. Jog: Press A to release A, and the rest of the keys are analogized. Interlock: Press A to open, press B and then A to close, B to open. A B can only keep one key open. Working mode setting: (switch the setting on the printed circuit board with a jump cap when power is off): 1.A, B, C are all suspended: 1-15 all interlocked 2.A+L: 1-15 all jog 3.B+L: 1-15 all self-locking 4.C+L: 1-7 jog, 8-15 self-locking 5.A+B+L: 1-7 self-locking, 8-15 interlock 6.B+C+L: 1-7 jog, 8-15 interlock 7.A+C+L: 1-2 jog, 3-7 self-locking, 8-9 interlock, 10-11 interlock, 12-13 interlock, 14-15 interlock 8.A+B+C+L: 1-5 jog, 6-10 self-locking, 11-15 interlock Add or clear the remote control instructions: 1. Learning: Press the learning button on the receiving board (black round button on the printed circuit board) to light up and release, then press any button on the remote control to learn. After the green light flashes quickly, all the keys in the remote control are automatically completed. The device can control the operation. 2. can learn more than 20 different address codes 2262, 2260, 1527 chip equivalent frequency fixed code learning code wireless remote control; 3. Clear code: long press the button switch for more than 5 seconds, the green light flashes and then goes out, indicating that the clear code is successful.
