MAINTENANCE
Your CZ-20 doesn’t require a lot of care. It’s built with high-
quality materials, and it’s waterproof to a depth of 250 feet. But
there are a few things you should do to keep it in peak operating
condition.
Storage
1. If you’re not going to be using it for awhile, take
the batteries out. Acid damage caused by leaking
batteries can be severe.
2. Avoid extreme temperatures. Don’t leave it inside
a closed car sitting in the sun or even worse, in the
trunk of a car.
Cleaning
1. Sand and dirt between the coil “ears” and lower stem
will grind away the ears and stem.
2. The headphone ear pads may be removed, rinsed
and squeezed out to remove any sea water salt
build up.
3. Sand, silt or fine dirt between the upper and lower
stems will cause the lower stem to freeze up. Rinse
frequently.
4. Rinse the lower area under the two knobs on the
control panel thoroughly after use in salt water.
5. Always clean and dry the area around the battery
cover seal before opening.
Battery Compartment
1. Remove the battery cover and check for water
after each use in water.
2. Keep the sealing surfaces of the battery cover and
control housing clean and free of scratches and
nicks. Remove and clean the neoprene gasket
frequently. Lubricating the gasket is not required
or recommended unless it is nicked and/or cut, in
which case use only a very thin coating of
petroleum jelley. Do not use silicone grease.
