SETTING UP FOR LAND OR SHALLOW WATER
Put the headphones around your neck to keep them out of
the way while making the following adjustments:
1.
Adjust the stem length and coil angle so the search
coil rests flat on the ground about 6 inches in front
and slightly to the right of your foot (to the left of your
left foot if you’re left handed).
2.
Leave enough slack in the coil cable to allow the
coil to swivel as far as it can in either direction. The
coil wing nut should be tight enough to prevent the
coil from moving.

When searching on land
or in shallow water, keep
your arm straight and your
search coil no more than 2
inches above the ground.

MAINTENANCE
Your CZ-21 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.
Handling
1.
Do not drop your detector.
2.
Do not drop the housing directly on to the knobs.
Damage caused by impact is not warrantable.
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.
Damage from battery acid is not warrantable.
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
recommended. Clean the gasket with mild soap
and warm water only. Do not use petroleum jelly or
silicone grease at any time.
3.
Re-install gasket correctly
