11. Always remove the batteries if the unit is not in use for a long period of time.
12. Noise and audio distortion may occur when the batteries are old. Replace the batteries with new alkaline
batteries or fully charged rechargeable batteries.
13. There is a dirt filter below the filter cover in ‘figure a’ below. This dirt filter is used to protect the internal air
equalization filter (there is no access to the internal air filter). The internal air filter equalizes the air pressure
inside and outside the box. This internal air filter protects the speaker from damage in the event of high
pressurized use such as airplanes or mountain climbing. The dirt filter only needs to be replaced if there are
large amounts of dirt or grim covering the ‘filter cover’. Please see below for the dirt filter replacement
procedure:
