Key Finder with Four Receivers

This radio-frequency key finder includes one handheld transmitter and four colour-coded receivers to help locate keys, wallets, remotes and other everyday items. Each receiver can be attached using the supplied keychain rings, adhesive strips or tag stickers. The system is designed for household use and operates on standard replaceable batteries.

Range and Signal Limits

The quoted working distance of 90ft to 130ft applies only to open space without obstructions. Walls, doors, furniture and other barriers will reduce the effective range. The 433.92 MHz signal penetrates typical indoor obstacles but performance varies with building materials and layout. Sound output reaches 75dB to 80dB to aid location by ear.

Setup Requirements

The transmitter requires two AAA 1.5V batteries and each receiver uses a CR2032 cell, all included in the package. Do not mix old and new cells or combine alkaline, carbon-zinc and rechargeable types. The product contains small parts and carries a choking hazard warning for children under three years.
