indicator of the probe will light up.

7.3 Battery replacement

When the power of the batteries is becoming exhausted,
the LED becomes perceptibly darker while the sensor unit
still works faultlessly. Use the test magnet, which is located
in the cap of the housing of the Magnet-Ex 12, to check
the brightness and the proper functioning of the LED. If the
LED is becoming darker or does not light up at all, you
have to replace the batteries (always outside the Ex-area).
Only type-tested batteries are to be used (refer to the
table with type-tested batteries under section 6, „Technical
specifications"). The use of any other type of batteries is
strictly forbidden.
In order to replace the batteries, first remove the cap of the
housing by unscrewing in an anti-clockwise direction.

screwing it in a clockwise direction.

- P lease ensure that all used batteries are properly
disposed of in an environmentally friendly manner.
