Key specifications

• System type: Radio-based remote control
• Components: ROG-21 receiver and P-457/2 transmitter
• Compatibility: Standard electrical installations
• Installation method: Flush-mounted
• Application: Lighting and electrical device management

How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. The ROG-21 receiver is typically installed within a flush-mounted box behind a switch or near the device to be controlled. Once the receiver is wired into the power circuit, it must be paired with the P-457/2 transmitter according to the manufacturer's pairing procedure. After successful synchronization, the transmitter can be used to toggle the connected electrical load remotely, providing convenient control from any location within the effective signal range.

What to consider before purchase

• Verify that the electrical load of the connected device does not exceed the receiver's rated capacity
• Ensure the installation location has sufficient space for the flush-mounted receiver
• Check for potential signal obstructions in the intended operating area

Usage recommendations

For optimal performance, avoid installing the receiver inside metal enclosures, as these can significantly reduce the radio signal range. Regularly check the battery status of the transmitter to ensure uninterrupted operation.
