Operation

The md-3003b/b1 operates on one 9 volt standard or rechargeable battery . to install the battery ,slide off the battery cover and place the battery into its compartment while matching the +/-symbols.

Turn the unit on by pushing the on/off switch until it clicks on and the green LED is lit. The detector is now operational although an increase insensitivity adjuster until the red LED is lit and a constant audio tune is heard. Turn the sensitivity adjuster(anti-clock wise)until the red LED just goes out the tone fades, the detector is now tuned for optimum sensitivity and depth range.

Holding the unit with the detection face towards the surface, sweep backwards and forwards continuously at a height of 10-30mm above the area to be scanned.

The presence of metal will be indicated by the audio warning tone and red light coming on, if the detector is held still over a metal object the detection signal will automatically reduce, therefore it is important that the unit is continually scanning the surface when is use.

Performance

The sensitivity of the detector is determined primarily by the size, shape and composition of the object to be detected.

Typical performance figures are given below:

Maximum detection range

Low sensitivity operation

Press the ;pw sensitivity switch during detection, scanner will then only respond to bigger metal objects such as a hand gun knife etc and will not respond to small metal s such as a coin, key, hatpin, etc do not release the low sensitivity switch until you compete low sensitivity detection.

Rechargeable battery socket

You may use a 9volt rechargeable battery to power the detector

It takes four to six hours to fully charge the battery. The battery charger socket is located at the side of the detector.

Note: turn off the detector when charging it,

Vibrator Button

The detector is equipped with a vibrator button also located at the side of the detector. Vibration function should be used in noisy work situations or in places where the operator does not wish for the audio tune to be heard in his surrounding area. press this button, vibrator works: release it ,audio tune works.

Note

If the green light goes out completely or fails to come on or if the unit is making unfamiliar audio tunes ,the unit is unstable and should not be used until the battery is recharged or replaced.

If the unit is not to be used for a certain length of time it is advisable to remove the battery to avoid battery to avoid battery leakage which could cause serious damage to the detector.
