Read that receiver’s model number rather than relying only on the operator brand. Where a separate receiver has been added, its radio compatibility can differ from the original equipment’s built-in control system.\u003c\/p\u003e\u003cp\u003eFor an existing remote that has become unreliable, check the specified battery and follow the receiver’s programming instructions before assuming the receiver needs replacement. A weak signal, a damaged remote and a lost enrollment are different problems. If several users need access, also review the receiver’s management procedure so a replacement remote is enrolled without unintentionally removing other authorized transmitters.\u003c\/p\u003e\u003ch2\u003eSpecifications and Product Identification\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e971LM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupplier manufacturer reference\u003c\/td\u003e\n\u003ctd\u003eG971LM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eButtons\u003c\/td\u003e\n\u003ctd\u003eOne\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRadio system\u003c\/td\u003e\n\u003ctd\u003e390MHz Security+ rolling code\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReplacement battery\u003c\/td\u003e\n\u003ctd\u003eOne 3V CR2032 coin cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExample compatible receiver\u003c\/td\u003e\n\u003ctd\u003e\n\u003ca href=\"https:\/\/garage-doorparts.com\/products\/liftmaster-412hm-coaxial-receiver-operator\"\u003e412HM\u003c\/a\u003e, as listed by the manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eBefore Ordering\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRecord the receiver model and confirm 390MHz Security+ rolling-code support.\u003c\/li\u003e\n\u003cli\u003eIdentify whether the receiver is built in or separately installed.\u003c\/li\u003e\n\u003cli\u003eConfirm the supplier’s current legacy-stock offer and included accessories.\u003c\/li\u003e\n\u003cli\u003ePlan enrollment and any lost-remote deletion using the exact receiver instructions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis listing is for the single-button remote.
