Usage Instructions

Remote Control Operation

1. Power On/Off: The remote control is used to remotely control the power on/off of all connected devices.
2. Turning On: Press and hold the remote control button (indicated by the symbol in the original text, assumed to be a power button icon) to turn on the device. The remote control indicator light will illuminate simultaneously.
3. Turning Off: Press and hold the same remote control button again to turn off the device. The remote control indicator light will turn off when the button is released.
4. Default State: The default initial state of the device is off.

Receiving Module Functionality

• When the remote control button is pressed, the MCU detects the button closure and modulates a transmission signal through the RF section of the integrated chip at 433.92 MHz.
• Upon button press, the receiving module decodes the signal and outputs a high level on the DATA pin.
• When the button is released, the receiving module fails to decode the signal, resulting in a low-level output on the DATA pin.

Troubleshooting

• Device not responding: Ensure the remote control batteries are not depleted. Check that the receiving module is properly powered and connected to the device. Verify that there are no obstructions between the remote control and the receiving module.
• Indicator light not illuminating: If the remote control indicator light does not illuminate when the button is pressed, the remote control battery may be dead or the remote control itself may be faulty.
• Interference: This device complies with part 15 of the FCC Rules, meaning it should not cause harmful interference and must accept any interference received. If you experience unexpected operation, try moving the device away from other electronic equipment that might be causing interference.

FCC Caution

This device is with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

1. This deviæ may not cause harmful interference, and
2. This device must accept any interferenæ received, including interference that may cause undesired operation.

Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment,

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio. However, there is no guarantee that interferenæ Will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienæd radi0/TV technician for help.

The deviæ has been evaluated to meet general RF exposure requirements. The device can be used in portable condition without restriction.
