Features: 1.EASY TO USE: Waterproof single way controller using the brand microcontroller independent programming, functional diversity, to achieve multiple control mode, by a single key to learn the code convenient and fast. 2.WIDE VOLTAGE: Industrial remote control switch adopts wide voltage power management chip to make its working voltage range wide. It can be used for lighting control, smart home control and other fields. 3.SELF PROGRAMMING: The waterproof 4 key remote control supports self programming, which can be used more widely. Support jog, self locking, interlocking and time delay 4 operating modes. 4.ANTI INTERFERENCE: Remote control uses GFSK signal transmission mode, which is free from motor and other signal interference, making the signal stable when the remote control is in long distance. 5.WATERPROOF: 433MHz wireless transmitter push button switch with airtight silicone shell design, with waterproof function. This remote control is used with waterproof single way controller. specification:Item Type: Industrial Remote Switch Material: ABS, Silicone Operating Frequency: 433MHz Operating Modes: Jog Mode, Self Locking Mode, Interlock Mode, Time Delay Mode Output Mode: Terminal Demodulation Mode: GFSK Control Mode: Waterproof Four Key Remote Control Code Format: Custom Code Remote Control Battery: 2 x AA Batteries (Not Included) Learning code operation: Jog learning code: After the controller is connected to the power supply, short press the learning code key (press once the light flashes once), and then long press the remote control button for 3 seconds, the controller light flashes to indicate the successful learning code, and the working mode is jog mode. Self locking learning code: After the controller is connected to the power supply, short press the learning code key twice (press once the light flashes once), then long press the remote control button for 3 seconds, the controller light flashes to indicate successful learning code, and the working mode is automatic mode. Interlocking learning code: After the controller is connected to the power supply, short press three times to learn the code key (press once the light flashes once), then long press a button of the remote control for 3 seconds (such as A key), the controller indicator light flashes and then lights up, then press another button of the remote control (such as B key) The controller indicator light flashes to indicate successful learning code, the working mode is interlocking mode (such as AB interlock). Delay 5 seconds to learn the code: Controller connected to the power short press four times to learn the code key (press once the light flashes once), and then long press the remote control button for 3 seconds, the controller indicator light flashes to indicate the success of learning the code, the working mode is delayed 5 seconds to automatically shut down mode. Delay 10 seconds to learn the code: After the controller is connected to the power supply, short press five times to learn the code key (press once the light flashes once), and then long press the remote control button for 3 seconds, the controller light flashes to indicate the success of learning the code, and the working mode is delayed for 10 seconds automatic shutdown mode. Delayed 15 seconds to learn the code: After the controller is connected to the power supply, short press six times to learn the code key (press once the light flashes once), then long press the remote control button for 3 seconds, the controller light flashes to indicate the success of learning the code, the working mode is delayed 15 seconds to automatically shut off mode. Delay 20 seconds to learn the code: After the controller is connected to the power supply, short press seven times to learn the code key (press once the light flashes once), and then long press the remote control button for 3 seconds, the controller light flashes to indicate the success of learning the code, and the working mode is 20 seconds delayed automatic shutdown mode. PackageList: 1 x Controller 1 x Remote Control Note1. The battery voltage should not exceed the operating voltage range. 2. In the wireless interference is relatively large environment, the transmission distance may be reduced. 3. Keep it out of the touch of children. 4. Prohibit use in a humid environment, otherwise it may cause damage to the remote control.
