How to clean and maintain your white noise generator (WNG)
3
The battery compartment - On/Off is operated by the battery
compartment on the back of the device. If it is difficult to close the
battery door: Check that the battery is inserted correctly and the “+”
symbol is facing upwards. If the battery is not inserted correctly, the
device will not work and the battery door can be damaged.
Low power: You will hear two beeps when the battery is low. You will
have approximately 30 minutes to change the battery.
We recommend that you always have a new battery on hand.
The tube and dome need to be changed every 6 months. This is
because they can become blocked due to wax and dirt and
potentially affects the output from the WNG. If they become
completely blocked it may seem like the device has stopped working
all together. (Further information is in this booklet regarding cleaning
and changing tubes and domes)
The tubes are also colour co-ordinated.
