Safety first: No electrical work is required for this procedure.

• 1. Unlock sequence: Refer to your Sundance owner's manual for the specific button combination to unlock the panel (commonly holding certain buttons for 3–5 seconds).
• 2. Check for stuck buttons: Press each button individually to ensure none are physically stuck or damaged.
• 3. Power cycle: Turn power OFF for 30 seconds and back ON. If LOC returns immediately without pressing any buttons, the keypad may be faulty.
• When to call a technician: If the panel will not unlock or random buttons activate, the topside control panel may need replacement.
