Programming your 94330E

Setup depends on the exact receiver and hardware revision. These model notes do not establish a complete pairing sequence for your equipment.

Match both the remote and opener or external receiver. Keep the door or gate in sight and clear of people. Do not hold a LEARN button or erase memory unless the instructions for that exact equipment require it.

Compatibility & exclusions

Matching rolling-code receiver required; not interchangeable merely because frequency matches.

94334E English says two CR2025 cells; Danish says one. Do not guess quantity. Other models retain manufacturer battery part numbers rather than unverified retail equivalents.
