## Long description

SATEL MK-DF3-4 is an RFID proximity key fob in a compact keychain format designed for everyday use as an access token. The device provides contactless user identification for compatible access control systems and alarm panels, allowing quick presentation to card readers for door entry, arming/disarming, and user authentication in residential and commercial installations. Its small, lightweight design makes it convenient to carry on a keyring and simplifies routine access tasks without the need for larger cards.
Advantages
The key fob offers reliable proximity reading and fast, contactless interaction with readers that support its RFID frequency and format. Its compact form factor and durable casing reduce wear during daily use while remaining unobtrusive on a keyring. Because it uses standard proximity technology, the token integrates with existing systems that accept compatible tags, simplifying user management and distribution for facilities that require secure yet convenient access methods.

How to use
Attach the SATEL MK-DF3-4 key fob to a keyring and present it to a compatible proximity reader at the recommended reading distance until the reader indicates acceptance (visual or audible confirmation). For initial deployment, enroll the token in the access control system or alarm panel according to the system manufacturer's programming procedure so the system recognizes the token's identifier. After programming, use the fob for routine door entry, arming and disarming, or other authenticated operations supported by the connected equipment.
Usage recommendations
To maintain reliable operation, avoid exposing the key fob to prolonged direct sunlight, extreme temperatures, or heavy mechanical impact. Keep the token clean and present it to readers at the typical operating distance without additional covers that could obstruct the signal. For secure management, follow site procedures for enrollment, deactivation of lost tokens, and assignment of access rights within the control system.
