3. INSTALLATION
• Be sure to position the speaker with its front facing down from
the horizontal axis. Doing otherwise may cause rainwater
to accumulate inside the opening, possibly resulting in unit
malfunction.
• Do not use the speaker in locations such as poolside where
the speaker is always exposed to water splash, or in high-
temperature and high-humidity locations such as bathrooms
and steam saunas where dew condensation may form.
Besides, do not dash water directly on the speaker.
