1. POWER/VOLUME CONTROL:
Turns the power on and
off. Also controls the target response volume in the
headphones. The volume control should be set no
louder than comfortable when the searchcoil is
passed over a large, close target.
2. DISCRIMINATION CONTROL:
A full range trash rejection
control. All types of metal are detected at the zero
level and most small pieces of trash are eliminated at
the maximum level of ten.
3. LED:
The clear plastic window between the SENSITIVITY
and VOLUME controls contains an LED (Light Emitting
Diode) which flashes red when a target is detected or
the batteries are being tested.
4. BATTERY TEST/SENSITIVITY CONTROL:
Checks battery
condition and controls the sensitivity to targets. A
setting of 10 gives maximum sensitivity and is used
for most treasure hunting conditions. To check the
batteries, turn the VOLUME control to 10 and click
the BATTERY TEST/SENSITIVITY control momentarily in
and out of the “Battery Test” position. Fully charged
batteries will give a loud tone in the earphones and a
bright red light in the LED window. Weak batteries will
give a faint tone and a dim light. It’s time to replace
the batteries when the light goes out.

MAINTENANCE
CLEANING
Hose down your 1280-X with clean fresh water whenever you’ve
had it on the beach or in the water. Pay particular attention to the
following areas:
1.
Stem adapter. Sand or dirt between the coil “ears”
and stem adapter will literally grind away the ears and
adapter.
2.
Headphone. The ear pads may be removed, rinsed and
squeezed out to remove any seawater salt build up. Rinse
out the cups to keep the vent holes clear.
NOTE: These
vent holes MUST be kept clear when diving to equalize
ear pressure.
3.
Between the upper and lower stems. Sand, silt or fine dirt
will cause the lower stem to freeze up.
4.
Control Panel. Rinse the area under the three knobs
thoroughly.
5.
Battery Cover. 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. Cleaning
the gasket should only be done by using mild soap and
warm water. Do not use petroleum jelly or silicone grease
at any time.
STORAGE
Remove the batteries from the battery pack when storing your
1280-X for extended periods to prevent damage caused by battery
leakage.
Never leave your 1280-X in an auto trunk or even in a closed
passenger compartment during hot weather. Temperatures in
excess of 120°F are possible which could damage electronic
components and ruin the batteries.
