Warnings
ESD
When electrical replacement or disassembly is taking place, use an ESD-mat. The
internal electronics are very sensitive to static electricity.
Handling
Wear cotton gloves to avoid any fingerprints on the product.
The surfaces on the product are very sensitive, so handling should be done with
great care to avoid damage.
Cleaning
Clean the surfaces of the BeoLab 4000 MKII using a soft, lintfree cloth which you
have wrung firmly in a solution of lukewarm water containing a few drops of mild
household cleaner, for example a dish washing detergent. The cooling fins on the
rear may be cleaned using a soft brush or a vacuum cleaner. The front cloth may
be cleaned with a vacuum cleaner set to the lowest level.
Note: Never use alcohol or other solvents to clean any part of the BeoLab 4000 MKII !
Insulation test
The product 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.
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 10 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).
