Power and compatibility

The supplier’s general note calls for a separate 12V 3A adapter, but individual models have different power arrangements. Confirm the exact model’s voltage label, plug and included accessories before connecting power; never assume every option accepts mains power. Supplier maximum wattages are not guaranteed continuous ratings. Actual output depends on the supply and speakers. Allow for supplier-listed measurement differences of 1–3cm and small colour differences caused by lighting or screen settings.
