DETECTOR FEATURES
1. Quick-Change Battery Compartment
Use a coin or screwdriver to open compartment.
Insert circular cam lock and twist to secure in closed position.
2. All-Metal Detection
Detects all types of metals.
Will not detector non-metallic objects or weapons that do not contain metal.
3. Momentary Low Detection
While holding down the "Momentary Low" switch, the detection range will be reduced.
a) Very small metal objects, such as the metal rivets sewn into clothing, will not be
detected beyond a range of one inch from the object.
INTERFERENCE ELIMINATION FEATURES
• 3 Operating frequency selections to eliminate
electromagnetic interference from other devices
OPERATING FREQUENCY
7.1 kHz
POWER SUPPLY
• Requires (1) 9-Volt battery
(not included)
• Low Battery LED indicator
MOMENTARY LOW OPERATION
• Minimizes Interference from
environmental metal objects
• Can eliminate signals from very
small metal objects
COMFORT
GRIP
OPERATOR DETECTION ALERTS
• Audio Alert – High Pitch Sound
• Vibration Alert
• LED Target Indicator - Red
b) Large environmental metal objects, such as the metal reinforcing bars in floors,
will not be detected beyond a range of several inches.
Upon release of the "Momentary Low" switch, the detector will return to Normal Operation.
4. Silent Operation
Position the Silent/Audio switch in the "Silent/Vibrate" position and:
a) The detector will NOT emit the High-Pitch tone upon the detection of metal objects.
b) The vibrator will activate upon the detection of a metal object, and the "Target"
LED indicator will illuminate.
5. Operating Frequency Selection
Chose from two alternate operating frequencies in the event of electromagnetic
interference from other electronic devices.
6. Low Battery Indication
When battery needs to be replaced, Low Battery LED will illuminate.
7. Visual Target Response
Red LED flashes when a metal object is located
8. Comfort Hand Grip
b) Large environmental metal objects, such as the metal reinforcing bars in floors,
will not be detected beyond a range of several inches.
Upon release of the "Momentary Low" switch, the detector will return to Normal Operation.
4. Silent Operation
Position the Silent/Audio switch in the "Silent/Vibrate" position and:
a) The detector will NOT emit the High-Pitch tone upon the detection of metal objects.
First Time Operation
To Operate the Detector,
1) Install the Batteries
a. Use a 9-volt ALKALINE battery only (battery not included)
b. Install battery with correct polarity
(align "+" on detector housing with "+" on battery)
c. The battery cover opens and closes with a coin or screwdriver
2) Set the On switch to "ON"
"ON" is the middle position
3) Select Audio or Vibrate Mode
4) Sweep the Detector over the target area.
Detector must be IN MOTION to detect metal
5) Read this manual for proper training in the detection of metal objects
First Time Operation
To Operate the Detector,
1) Install the Batteries
a. Use a 9-volt ALKALINE battery only (battery not included)
b. Install battery with correct polarity
Batteries
Use 9-Volt ALKALINE battery only (battery not included)
Low Battery Alert
The Yellow LED indicator light will illuminate and remain illuminated before the batteries
are discharged to the point at which the detector has lost any of its metal detecting
range.
In order to guarantee maximum detection at all times, replace battery as soon as yellow
light illuminates.
The detector will continue to operate, at a lower sensitivity, after the Low Battery
Indicator is illuminated. Replace batteries as soon as possible after the indicator
illuminates.
If you plan to store the CW20™
for several days or more,
remove the battery.

Power Switch with Momentary Low
The Power switch has 2 "ON" positions and a forward "OFF" position.
The detector is OFF with the switch in the "UP" position
The detector is ON with the switch in the "MIDDLE" position
The detector is in
MOMENTARY LOW operation with the switch
held in the "DOWN" position.
While holding down the "Momentary Low" switch, the detection range will be reduced.
a) Very small metal objects, such as the metal rivets sewn into clothing, will not be
detected beyond a range of one inch from the object.

Body Scanning for the Detection of
Metal Objects
Always test the detector before operation. Sweep the detector across a known
metal object, and verify detection with audio, vibratory, and visual feedback.
Body Scanning for the Detection of
Metal Objects
Always test the detector before operation. Sweep the detector across a known
metal object, and verify detection with audio, vibratory, and visual feedback.
Motion is Required: The metal detector must be IN MOTION,
sweeping across the target area, to detect
the presence of metal.
The subject should stand upright, with arms and legs extended.
Sweep the detector over the subject, with a smooth, even motion, about one inch from the body.
Avoid making physical contact between the subject and the detector.
Press and Hold the "Momentary Low" switch to eliminate interference from the metal bars in
floors, or from very small metal objects, such as rivets or zippers sewn into clothing.
CAUTION: Use in the MOMENTARY LOW mode will desensitize the detector.
Use the Momentary Low switch only after the detection of metal, and the
verification of the absence of a larger metal object
Scanning Personnel in security situations should be properly trained and supervised.
This detector will not detect non-metallic objects.
