• Avoid mounting the speakers directly to ski lift poles or other objects that give the speakers great shocks, as
doing otherwise could cause the speakers to fail.
• The speaker cannot be used in locations that always expose the unit to water splash (such as locations
close to a swimming pool) or in locations of high temperature and humidity where dew condensations could
be formed. Also, do not dash water directly over the unit.
4. IMPEDANCE CHANGE
When changing the impedance, remove a waterproof cap as
shown in the figure on the right, then set the slot to the desired
impedance using a screwdriver. (In the figure, the impedance is
set for 500 Ω.) Replace the cap after setting completion.
