INSULATION TEST
Static electricity may destroy the product!
A static-protective fi eld service kit must always be used when replacecement of the
modules takes place.
Please note:
When mains voltage on the TV is required, remove the connection from the TV to
the ESD mat.
WARNING
Short-circuit and overcharging of some types of lithium batteries may result in a
violent explosion.
Each set must be insulation 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 of the
terminals of the insulation tester. Connect the other terminal to ground on the
VHF/UHF aerial socket.
NOTE!
To avoid damaging the set 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 is
obtained. Maintain that voltage for one second, then slowly turn it down again.
