Three toggle switches for '12V BATTERY IN', 'POWER', and 'LED POWER' are all in the 'OFF' position. White text and symbols identify functions and warnings, notably 'LIVERPOOL' centrally located. A product information label printed on the panel explicitly states the manufacturer/importer location as 'PT.Asatron Indo Agung, Padalarang - Bandung Indonesia'.
