RIGHT SIDE
Important: Maintaining Waterproofness
If the caps or the door on either side panel are not properly closed, the unit
is NOT watertight.
To close properly, turn the cap clockwise so the cap’s arrow point lines up
with the locked symbol .
To access the connections, turn the cap counterclockwise so the cap’s arrow
point lines up with the unlocked symbol , then pull tab on cap to open.
Waterproof Caps
To open, squeeze the spring loaded latch to release the locking tabs, then
pull open the door using the handle.
Door cannot be opened unless the spring loaded latch is squeezed while pulling
the door open. The waterproof seal on the door will create some resistance
while opening the door.
To close, push the door firmly until it ‘clicks’ into place and the locking
tabs are secured into position. If needed, press on the door firmly near the
locking tabs to ensure the door is fully closed and locked. The waterproof
seal on the door will create some resistance while closing the door.
To ensure the compartment is watertight:
- Visually check the seal on the door to ensure it is free from dirt and other contaminants, and also check for any damage to the seal. If the seal is damaged or dirty the compartment may not be waterproof.
- Ensure the door is fully seated into its closed and locked position. If the door is not properly closed the compartment may not be waterproof.
- Ensure no obstruction is keeping the door from closing properly. If the door is not properly closed the compartment may not be waterproof.

are clean, free from sand or debris, and correctly fitted. The speaker will
only meet IP67 ratings if all rubber seals, gasket(s) and cover(s) / cap(s)
are in place. If you notice a muffling of audio after submersion, gently shake
the unit to clear excess water. If your speaker is exposed to salt water,
clean it thoroughly after use with fresh water.
