Do I need to replace the cabinet?
No. The Retrofit PCB is designed to drop into existing GEM/TECH enclosures.

Does it support the Atlantis Position Sensor (APS)?
Yes. APS enables electronic limits and precise positioning.

Who should install it?
Professional installers only. This is not a DIY product.

Phone (Remote Support): +1 (561) 410-6821
Hours: Monday–Friday, 9:00 AM – 5:00 PM EST

Remote support is available when the lift is connected to the internet (Wi-Fi or cellular).

1. Power down the system and verify zero voltage
2. Remove the legacy GEM/TECH control board
3. Mount the Atlantis Mini Retrofit PCB inside the existing cabinet
4. Connect power, switches, and key-detect wiring per instructions
5. Run the setup wizard and configure limits if needed

Pre-configured units ship ready for standard limit-switch operation with selectable Manual or Auto modes.

Additional configuration is only required when installing APS or advanced features.

Professional installation required.

This product must be installed and serviced by qualified professionals. High voltage is present inside lift control systems and can cause serious injury or death. Always disconnect and verify power before servicing.

Read and agree to the Atlantis Control Systems Terms of Use before attempting to install, configure, or operate this product. Use of this product constitutes acceptance of those terms.

Atlantis Control Systems is not responsible for damage, injury, or loss caused by improper installation, wiring, configuration, or use. Always follow applicable electrical codes and marine safety requirements.

¹ Atlantis Boater app access requires an active subscription; monthly or annual fees apply.

² Some legacy control enclosures, including certain TECH and GEM models, may be smaller and may not conventionally accommodate the Atlantis control board. Enclosures with dimensions of at least 12 × 10 × 5½ inches are considered standard and typically allow for a straightforward installation. The wiring included with the Atlantis kit is generally sufficient; however, in smaller enclosures, the existing power and auxiliary (AUX) wiring within the enclosure may require extension to support alternative mounting methods, such as a lid-mounted control board, in order to address space constraints.
