CONTROL PANEL

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.
