34、nsulation tested after having been dismantled. Make the test when the set has been reassembled and is ready to be returned to the customer.Flashovers must not occur during the testing procedure!Make the insulation test as follows:Short-circuit the two pins of the mains plug and connect them to one o

35、f the terminals of the insulation tester. Connect the other terminal to ground on the aerial socket.NOTE!To avoid damaging the HDR 1 it is essential that both terminals of the insulation tester have good contact.Slowly turn the voltage control of the insulation tester until a voltage of 2.5 kV ac an

36、d max. 10mA is obtained. Maintain that voltage for one second, then slowly turn it down to 0 V ac again.Monitor informationThe scope of this check is, to ensure the following:- The product has maintained the correct identity.- The error code register is cleared.ProcedureEnter Service menu A/V board
