Optionally fit a second plug-and-play tuner to receive additional signal types. Use the included remote control or compatible mobile apps (for example dreamDroid on Android or e2Remote Lite on Apple devices) to navigate Enigma 2, schedule recordings and manage plugins. For network features, connect the device to your router via the Ethernet port or add an external Wi‑Fi antenna for wireless access.

Usage recommendations

For reliable 4K recording and smooth transcoding, use a high-quality microSD card (class UHS‑I or better) or a quiet 2.5" HDD with sufficient capacity. Keep firmware and Enigma 2 plugins up to date to ensure compatibility with broadcast services. When streaming to multiple mobile devices, a stable wired Ethernet connection or strong Wi‑Fi signal is recommended to minimise buffering.
