Final check after repair
The final check after repair describes the activities that are needed to ensure the
product will be returned in perfect condition to the customer. Follow the
procedures below:
Insulation test
The product must be insulation tested after having been dismantled. Make the
test when the product has been reassembled and is ready to be returned to the
customer.
Flashover must not occur during the test .
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 Power Link socket.
! NOTE
To avoid damaging the product it is essential that both terminals of the insulation
tester have good contact.
During the test the current must not exceed 5 mA.
Slowly increase the voltage on the insulation tester until a voltage of 2.5 kV (ac) is
obtained. Maintain the voltage level for one second, then slowly decrease the
voltage to 0 V (ac).
Restore setup
Before the product is handed over to the customer ensure that:
- The position switch (FREE / WALL / CORNER) is in correct position.
- The role switch (LEFT / RIGHT / WIRELESS) is in correct position.

before it is returned to the customer. This is to ensure the customer receives the
best possible experience. Follow the procedure on page 3.6.

done by a sound test with ServiceTool. Follow the procedure on page 2.5.
