I/O,

SENSITIVITY

___________________________ 

Turn the machine on with the SENSITIVITY I/O control. 

You will hear some quick "beeps" which will tell you 

that the detector is correctly operating. 

Then you can detect.  

Avoid testing your detector inside your house or in shops 

 because you can encounter a lot of metallic and 

electromagnetic pollution (reinforced concrete, metallic girder  

and fluorescent lights). 

The control also enables you to adjust the sensitivity of your detector. 

The sensitivity level determines the depth of detection and the stability 

of your machine. It can be adjusted to suit the environment so as not 

to be plagued with false signals. 

Please note that this new detector has a more advanced 

SENSITIVITY setting compared to previous GMAXX II model, 

enabling you to make gradual adjustments to help alleviate false 

signals. 

The range of adjustments has been widened to offer more 

sensitive adjustments at the top end of the range. 

You should therefore not be surprised if you have to lower the 

potentiometer settings on bad ground. The performance of the 

machine will not diminish.
