The Marantec Digital 384 is a four-button garage door opener remote designed for Marantec operators, giving you secure, reliable control of up to four doors, gates, or compatible Marantec receivers. It’s an OEM replacement transmitter for expanding your system or replacing a lost remote, built around Marantec’s encrypted rolling-code technology to help prevent code grabbing and unintended access. Compact and easy to carry, it’s well suited to residential use and light commercial applications that rely on Marantec controls.
Operating at 315 MHz for North American Marantec systems, the Digital 384 works with Marantec openers that use Marantec’s 315 MHz Digital radio technology, including many Synergy and earlier M-Line operators. It is not universal and will not operate other brands unless a Marantec external receiver is added. Power is supplied by a 3V CR2032 coin-cell battery, with an LED that confirms transmission. Programming can be completed at the opener using the learn/program button sequence, or by copying settings from an existing working Marantec remote with a Marantec programming connector when available. For best results, verify that your current opener or remote indicates 315 MHz before pairing.
